Iron preparations for plant nutrition. Chelated iron

To receive good harvests plants need to be provided not only with basic nutrients, but also with microelements. Iron, along with copper, zinc, boron, manganese, cobalt and molybdenum, is among the seven most important. Iron chelate allows you to effectively feed the plants with this element. About what it is, how to use the drug and cook it with your own hands, will be discussed in the material.

Benefits of chelated mineral supplements

First of all, it is important to understand that nutrients are absorbed by plants only in a bioavailable form. Ordinary mineral fertilizers ( see → ) before it can be taken up by plants, it often has to go through a series of transformations. In chelated substances, the substances are initially in a bioavailable state. Chelated fertilizers penetrate better into plant cells, due to which they are absorbed by 90%. Ordinary mineral compounds absorb only 40-70%.

In addition to this important advantage, chelated fertilizers have an impressive list of others:

• do not have a phytotoxic effect;
• do not affect the acidity of the soil;
• do not accumulate in the soil, causing its salinization;
• do not enter into a chemical reaction with other substances, forming unwanted compounds;
• perfectly soluble in water and well absorbed by the roots and leaves.

Being organomineral fertilizers, chelates do not harm ecological state site and can be used on soils of any type.

Iron chelate: characteristics and purpose

Externally, iron chelate is a dark red fine powder. molecules given substance are complexes formed by iron itself and a chelating agent. Various organic acids can act as the latter:

As can be seen from the table, different iron chelates exhibit unequal stability in the external environment. So, for example, an EDTA-chelated preparation will work well in acidic soils, but will disintegrate in calcareous soils. These nuances must be considered when buying.

The main purpose of iron chelate is the treatment of non-infectious chlorosis caused by a deficiency of this trace element. Also, the drug can be used for prophylactic purposes.

Tip #1. Information about the chelating agent can be found on the package of the drug. It is usually given as a Latin abbreviation.

Signs of iron deficiency in plants

The most sensitive to iron deficiency in the soil are such crops as tomatoes, potatoes, cucumbers, raspberries, apple trees, apricots, cherries, cabbage, carrots, cucumbers, grapes and greenhouses. citrus plants. Their deficient state is accompanied by the following symptoms:

• the upper young leaves lose their color, the lower old ones remain green;
• chlorotic areas of pale yellow, almost white color appear between the veins;
• areas affected by chlorosis expand, capture the entire interveinal space, leaving only the veins green.

The plant, being unable to carry out photosynthesis normally, slows down growth, sheds flowers and ovaries. If new leaves appear on it, then they already turn out to be chlorotic when deployed.

Non-infectious chlorosis in plants occurs because chlorophyll in the cells ceases to be synthesized and is destroyed. All the described signs are a signal for immediate feeding of plants with iron chelate.

The effect of iron chelate on plants

Iron plays an important role in the biochemical processes occurring in the plant cell:

• participates in the synthesis of chlorophyll;
• participates in the transfer of electrons during photosynthesis;
• participates in the construction of proteins that restore nitrites and sulfates;
• involved in the synthesis of nucleic acids.

It follows that iron chelate can be used not only for the treatment and prevention of iron deficiency chlorosis. Treatment with this drug allows you to achieve the following goals:

• increase photosynthetic activity and cellular respiration of plants growing in the shade;
• improve the condition of seedlings in the absence of additional illumination with phytolamps;
• normalize nitrogen metabolism in cells and improve the absorption of other mineral elements;
• improve pollen quality, stimulate flowering and fruiting.

Thus, iron chelate indirectly affects the volume and quality of the crop.

Ways to use iron chelate

One of the advantages of iron chelate is that this drug is equally well absorbed through the roots and through the leaves. This property allows you to use it for top dressing by any means.

Most often, chelate solutions are used for leaf dressing. For this right amount powder dissolves in water. The concentration of the working solution is as follows:

• for feeding fruit trees - 5 g per 5 liters of water;
• for other crops - 5 g per 8 liters of water.

You can spray plants with iron chelate throughout the growing season. However, the greatest efficiency is observed when processing during the period of active growth - in late spring and the first half of summer. At this time, you need to do four foliar top dressing with an interval of 2 weeks.

Equally useful is the delivery of iron chelate with irrigation water. The solution is made in the same way as for spraying, only its concentration in any case should be 5 g of chelate per 5 liters of water. For 1 m 2 of soil during irrigation, you need to spend about 2 liters of working solution.

Important! If iron chelate treatment is carried out with medicinal purposes, stop feeding only after the disappearance of symptoms of chlorosis. This can be done both on the sheet and under the root. If the growing leaves acquire a normal color, then the iron deficiency is replenished.

Manufacturers of iron chelate and drug prices

Powdered iron chelate can be purchased from various agrochemical manufacturers:

Iron chelate can also be produced in liquid form. In particular, it is included in the "Hydroponics Kit Micro" solution, which can be used not only for hydroponic growing of plants, but also for watering the soil.

Do-it-yourself preparation of iron chelate

Given that the consumption of iron chelate and the working solution is quite high, and at least four treatments are required to achieve the effect, this drug cannot be called cheap. Fortunately, iron can be easily chelated at home. For this, substances that are available to any summer resident will fit:

• ascorbic or lemon acid, Apple vinegar;
• inkstone.

These acids form unstable compounds with iron molecules, so you need to prepare homemade chelates immediately before use. If they are stored for a long time, the solutions age, change color, and iron precipitates.

Citric acid has an important property that will allow not only to feed plants with iron. In biochemistry, there is such a thing as the Krebs cycle. This is the basis of plant cell metabolism, thanks to which it is supplied with energy. chemical reactions, occurring at the same time, occur with the participation of citric acid.

To make iron chelate, you need to take iron sulfate powder and citric acid in a ratio of 1: 1.5⊕ . For example, to prepare 1 liter of chelate solution

4 g of acid and 2.5 g of vitriol are required. First, the acid dissolves completely in water. Then vitriol is gradually mixed into the solution. The result is a lemon-colored liquid that contains 0.5 g/l of ferrous iron in the form of citrate.

If ascorbic acid in tablets is taken for chelation, it must be pure, without dyes and glucose. Tablets are pre-ground into powder. A half-liter jar of water will require 10 g of ascorbic acid. After dissolving the acid, 1 teaspoon of ferrous sulfate is introduced into the solution. Then everything is diluted with water - the final volume of liquid should be equal to 3 liters.

For normal growth and development, plants need different nutrients that they need to be supplied throughout their life. Iron chelate is the most important microfertilizer that provides reliable protection against the manifestation of a disease such as chlorosis. Another substance is used to improve the processes of photosynthesis in plants growing on poor soil.

Benefits of iron chelate for plants

The peculiarity of the substance is that it is iron in the chelate form. This allows it to be easily and completely absorbed by plants, providing them with a balanced diet for proper growth. For greens, iron is an intermediate. It does not require as much as macronutrients, but not as little as micronutrients. Therefore, this element is an indispensable component for plants.

Iron deficiency can be easily identified by appearance plants: a light leaf plate and typical green veins on it are all symptoms of chlorosis. The disease is formed against the background of a failure in the production of chlorophyll in the foliage.

Chlorosis manifests itself with a strong deficiency of iron in the soil or as a result of disturbances in the assimilation of the element in this form by the plant. To solve the problem, it is necessary to change the methods of agricultural technology and apply fertilizers.

Characteristics of microfertilizer

Iron is actively involved in metabolic processes, but is also part of the enzymes that normalize respiration and the formation of chlorophyll.

Key Features

Main positive traits chelated iron:

The main feature of the substance is its availability for plants. Many believe that rusty water is also a source of iron, but this is a misconception. Yes, it is there, but in this form the substance does not dissolve and can have a detrimental effect on the plant.

In some cases, even the element's accessible form may not be useful. For example:

1. If the soil contains dolomite or chalk. These two components reduce the access of the substance to the plant. Even if there is enough of it in the soil, there will still be a lack.
2. As a result of oxidation, the available form of iron may become inaccessible. This reaction occurs due to the interaction of the element with oxygen.

Application for plants

Iron occupies one of the leading places among all trace elements for plants. It is a guarantor of the timely biosynthesis of chlorophyll and a reliable protector against various diseases, including chlorosis. Promotes the proper development, vegetation and activation of all life processes that ensure the full growth of plants.

Regular use of microfertilizer guarantees:

This microfertilizer can be used as top dressing for foliar and root tillage. With significant signs of iron deficiency, the maximum effect can be achieved by using it in foliar treatment of affected leaves.

Fruit trees especially suffer from the lack of an element - pear, apple, plum, peach, cherry, citrus trees, as well as grapes grown on poor soils. Symptoms of the disease are expressed in poor yields, poor flowering and dull fruit color. The deficit also has a negative impact on vegetable crops ah - potatoes, tomatoes, cucumbers, corn, cabbage.

DIY chelated iron

Microfertilizer can be bought in specialty stores, but you can also prepare your own chelate at home, which will be more economical. Below are two methods that use iron sulfate, which is several times cheaper than the finished powder of the substance.

The first way - ascorbic acid

This method will require ascorbic acid, which can be purchased at any pharmacy. The only condition is that glucose should not be present in the composition of ascorbic acid.

Cooking steps:

• ascorbic acid (10 g) is added to a solution of ferrous sulfate (1 teaspoon per 500 ml of water);
• the resulting mixture is diluted with boiled water (3 liters), after stirring, an iron chelate is formed.

Everything, the solution is ready to use. The concentration of such a solution will be approximately equal to 0.5%, so it can be used for spraying.

The second way is citric acid

To prepare this method, citric acid is used, you can buy it at any grocery store. Manufacturing steps:

• citric acid (1 tablespoon) and iron sulfate (1 teaspoon) are introduced into boiled water (3 liters);
• when thoroughly mixed, a light orange mixture is obtained.

The main disadvantage of making iron chelate at home is that it cannot be stored for a long time, as the iron oxidizes and precipitates.

Instructions for use

As mentioned above, the solution is used as a root or foliar top dressing. Root top dressing is recommended for especially severe cases chlorosis, foliar - for the prevention of the disease. It is important to remember that iron chelate is a substance of the third class of danger to people, therefore, when working with it, it is necessary to use personal protective equipment.

Foliar processing

Foliar treatment means spraying with a solution of diseased trees or plants from a spray bottle. For preventive purposes, spraying is carried out 2 times, while diseased plants are sprayed 4 times.

The first treatment is carried out after the foliage unfolds, the next - after 14–21 days. Fruit trees it is desirable to spray 0.8% iron chelate, and vegetable, berry, field, ornamental crops and vineyards - with a solution of 0.4%.

root processing

For root treatment, a 0.8% solution is used. Use it for watering the plant directly under the root or in pre-prepared holes (20–25 cm).

Watering is carried out in the following proportions:

• 10-20 liters - per tree;
• 1-2 liters - per bush;
• 4-5 liters - per 100 square meters of vegetable or berry crops.

Other dosages can be read in the instructions for using liquid branded or chelated iron tablets. This is due to the content of ballast components in a solution or tablet. But when recalculated for the active substance, the concentration will still remain the same.

So, if the plants are ill with chlorosis or it is necessary to improve their photosynthesis, there is no better helper than iron chelate. Ease of preparation, application and its cheapness are indisputable arguments in favor of its use.

For the normal life of plants, various nutrients are required, with which they must be provided throughout the entire time with the only change in the amount and frequency of application depending on the time of year. One of the most important such elements for plants is iron chelate, which provides reliable protection against the manifestations of chlorosis.

Article outline

Features of the drug

The peculiarity of microfertilizer is that it is iron in chelate form. That allows it to be easily and completely absorbed by plants, providing good nutrition for normal growth. Iron for plants serves as an intermediate element: it is not needed as much as macronutrients, but not so little as micronutrients. This makes iron chelate indispensable for plants.

The lack of this element is easy to notice in appearance, it will be expressed in clear signs of chlorosis. The disease develops against the background of a violation of the production of chlorophyll in the leaves. Its main features are a light leaf plate and characteristic green veins on it.

The appearance of chlorosis occurs when there is an acute deficiency of iron in the soil or as a result of the restrictions that have arisen on plants to absorb it in this form. To solve this problem, it is necessary to revise the methods of agricultural technology, as well as fertilize with iron chelate fertilizer.

The main signs of chlorosis

If at least some of these signs occur, urgent measures must be taken and chlorosis treated.

What you need to know about plant chlorosis

Characteristics of microfertilizer

Iron is an active component for the life of plants, it is actively involved in metabolic processes, and is also one of the components of enzymes that provide respiration and the formation of chlorophyll.

The main positive qualities of iron chelate

1. Completely non-toxic.
2. Simultaneous use with mineral fertilizers is allowed.
3. It dissolves in water completely and is easily absorbed by plants.
4. Not affected by microorganisms.
5. It has a high transport activity and has a high permeability through the foliage.
6. Simultaneous use with pesticides is possible.
7. Versatility in use (used as foliar or root dressing).

An important feature of iron is its availability for plants. There is a misconception that rusty water (which can often be seen from a faucet) is also rich in iron. Yes, it is present there, but in this form it is completely insoluble, and sometimes harmful to plants.

There may also be such an option: if chalk or dolomite is included in the composition of the soil, then even the available form of iron under such conditions turns into a completely useless composition for plants. As a result, there will be a lack of this element with a sufficient amount of it in the soil.

The available form of iron can become inaccessible as a result of oxidation, which occurs when interacting with oxygen. After that, it is no longer possible to make the element available.

Features of the use of iron chelate for plants

Of all the trace elements for plants, it is iron that plays the leading role, since it guarantees the timeliness of chlorophyll biosynthesis, and is also a reliable shield against many diseases, and in particular chlorosis. For plants, the use of iron chelate plays an important role, as it contributes to the full development, vegetation and activation of all the necessary processes that ensure normal plant growth.

Regular use of fertilizer guarantees:

• development of sustainable plant immunity to any negative phenomena external environment;
• compensates for the lack of missing trace elements, which forms resistance to diseases;
• improves photosynthesis and plant respiration;
• stimulates active growth and full development of plants;
• eliminates iron deficiency;
• normalizes metabolism;
• provides a sufficient amount of chlorophyll in the leaves.

The use of iron chelate is possible during root tillage, during drip irrigation, and can also be used as foliar plant nutrition. The maximum effect with obvious signs of iron deficiency in plants can be achieved by foliar treatment of affected leaves.

It has been noticed that of the fruit trees most affected by iron deficiency: peach, pear, plum, cherry, apple, citrus trees, and in some cases grapes, provided that it is grown on carbonate or over-calcified soils. Signs of the disease can be expressed in poor flowering, weak fruit color, low tree yield. And also the deficiency of this element can significantly affect carrots, tomatoes, cucumbers, potatoes, cabbage, corn, raspberries.

The effect of the drug on indoor plants

Indoor plants are especially in need of the active iron element, as they have a limited space of the earth, in which the resulting lack of microelements can cause plant diseases, and even their death. There are several types of indoor crops that react sharply to a lack of iron in the ground:

• gardenia;
• azaleas;
• hydrangeas;
• clerodendrum;
• citrus crops.

Therefore, if any of the plants listed above are present in the house, you should know in advance that their normal life will require regular use of iron chelate for indoor plants. For this, manufacturers make specially small packaging of fertilizer.

Application for indoor plants also includes preventive measures to prevent the appearance of leaf chlorosis. Indoor cultures with iron content in pots are noticeably distinguished by their full and rapid development, and they also develop stable immunity to chlorosis and various stresses. However, in the event of a disease in houseplants, iron chelate can be easily dealt with, but treatment should not be delayed.

How to use microfertilizer

In the treatment of chlorosis and as a preventive measure, iron chelate fertilizer is used in various proportions, time intervals and duration of use.

Instructions for the use of iron chelate for plants for preventive purposes

It is necessary to dissolve 5 g of the drug in 10 liters of water and spray the foliage abundantly with the resulting solution, treat at least 2 times starting from the first appearance of the leaves and continuing the entire growing season with an interval of 2 weeks. The last treatment should be carried out before flowering. The consumption rate of the resulting drug is 1 liter per 10 square meters. m.

Instructions for the use of microfertilizer in the treatment of chlorosis

Dissolve 5 g of the substance in 5 liters of water for fruit trees and 8 liters of water for any other crops, then spray the foliage abundantly, process at least 4 times with a frequency of 2 weeks. To enhance the treatment, it is possible to carry out with strong chlorosis the root application of the drug; for this, dissolve 5 g of fertilizer per 5 liters of water and the consumption rate of the resulting drug is 2 liters per 1 sq. m.

During the use of the drug, it is necessary to observe general rules safety: when processing, wear gloves, change of clothes, a headgear, as well as during the spraying of the drug - goggles and a gauze bandage.

• In case of contact with skin or eyes, rinse immediately large quantity running water.
• At the end of work with the solution, wash your face and hands with soap and water.
• Fertilizer must be stored in a dry dark place excluding access by children. Shelf-life Unlimited. The storage temperature must be at least 0 degrees.

Iron chelate for strawberries - how to apply

Making iron chelate at home

In the case when there is no preparation at hand, and the plant needs to be saved, you can prepare iron chelate at home, but you cannot store the resulting solution, so you should use it on the day of preparation.

1. Option 1: You will need 1 liter of rainwater, in which you need to dissolve 4 g of citric acid, then add 2.5 g of iron sulfate. Stir the resulting solution until a uniform color of the liquid is obtained. The solution is ready.
2. Option 2: You will need 1 liter of rainwater, to which you need to add 10 g of ferrous sulfate and 20 g of ascorbic acid, mix everything thoroughly until the ingredients are completely dissolved.

These solutions listed above can be used for both foliar spraying and root watering. But when using the drug, it is necessary to follow all the recommendations in order to prevent excess iron in the soil (very rare).

Signs of excess iron in plants

• the general growth of the plant stops;
• leaf plates acquire a rich dark green color;
• leaves begin to fall for no apparent reason;
• black necrotic spots appear on the leaf plates;
• the absorption of phosphorus and calcium is difficult, therefore, signs of their deficiency appear.

Numerous positive reviews about iron chelate prove that this drug really helps to get rid of the problems of chlorosis, and also helps to develop stable plant immunity to all kinds negative factors environment, which guarantees the full growth and healthy appearance of the leaves.

The lack of trace elements in depleted soils has a detrimental effect on the development of plants. Particularly affected by the lack nutrients crops growing on alkaline soil in arid climates. For better assimilation of trace elements, chelation is used. What is iron chelate, and how is it useful for seedlings? Let's consider the issue in detail.

Chelates and their importance in horticulture

cultivated plants for proper development trace elements are required, which form the basis of their growth. Trace elements are involved in biochemical processes, regulate metabolism, activate enzymes. Trace elements increase plant immunity, resistance to adverse external factors.

For example, iron deficiency in the soil affects the quality of development of seedlings: the leaves turn yellow, the shoots dry out, the inflorescences do not gain strength, the fruits are poorly tied. Iron and other minerals are necessary for plants throughout the growing season in order for the leaf apparatus to actively produce chlorophyll.

Minerals are found in the soil, but over time their amount decreases. Experienced gardeners regularly contribute micro and macro elements, organic fertilizers and agrochemicals to replenish the missing substances.

Chelates are called fertilizers, in which inorganic substances enclosed in a nutritious organic shell. Thanks to this, seedlings can easily absorb the necessary trace elements. Chelates act as conductors that deliver trace elements to cultivated plants.

Important! Iron chelate provides the synthesis of chlorophyll.

Inorganic elements do not always manage to penetrate the leaf surface, and the organic coating provides them with access to plant tissues. The chelated shell reliably protects the microelements contained in it, at the same time allowing them to be easily absorbed by plants.

However, not every trace element is able to form chelate compounds. Therefore, chelated fertilizers can be created based on:

• gland;
• calcium;
• manganese;
• molybdenum;
• copper;
• magnesium;
• cobalt;
• zinc;
• boron.

Note! Potassium, phosphorus and nitrogen do not form a chelate form.

Chelated fertilizers are absorbed by plants by almost 90%, unlike conventional agrochemicals, because they do not interact with the soil. Chelating elements keep metal ions in a soluble form that is easily absorbed by plants. They combine well with pesticides, insecticides and other mineral fertilizers. However, farmers recommend pre-checking the preparations for compatibility.

Note! In nature, vitamin B12 and chlorophyll act as chelates.

Chelated fertilizers are used for seed dressing, and for, and for spraying seedlings. However, before buying the drug, it is necessary to clarify what type of chelates it contains, and for what type of soil it is used: the acidity index pH matters.

iron chelate

Iron chelate is produced either in tablet form with stabilizers, or in the form of a dark-colored ready-made solution. The working solution must be used on the day of preparation.

Chelating drugs are complex, and there are single ones. For example, Fe-DTPA or Fe-EDTA. Iron chelate for plants contains water-soluble ferrous ions Fe (II), with which you can:

• save the plant from yellowing leaves;
• prevent chlorosis (yellowing of the leaves);
• strengthen the resistance of plants to adverse conditions;
• enhance photosynthesis.

Chelated microfertilizers are especially needed for radishes and strawberries, which draw many micronutrients from the soil. Farmers use iron chelate together with boron. The soil nourished with boron and iron allows you to harvest a rich strawberry crop from the same site for 7-8 years.

The soil contains iron oxide (rust) in excess, but this compound is not useful for plants. The formation of chlorophyll requires the divalent compound Fe(II), which is more actively absorbed by plant tissues. The chelate shell quickly breaks down into its constituents - water and carbon. These are safe compounds that do not clog the soil.

Sandstones are the poorest in iron; vegetation on such soils always becomes ill with chlorosis. Clay soils and chernozem suffer less from a lack of iron compounds, so fertilizer is used less frequently - once every 3 or 5 years.

Benefits of iron chelate:

• dissolves well in water;
• non-toxic to plants;
• quickly absorbed by plant tissues;
• mixes well with other fertilizers and pesticides;
• used for foliar and root feeding.

Note! Rusty water cannot serve as a source of iron, since it is in a form that is difficult for plants to access.

Effect of fertilizer on plants:

• strengthens resistance to adverse weather conditions;
• increases resistance to diseases;
• activates the growth and development of seedlings;
• corrects metabolic processes;
• promotes the production of chlorophyll.

Fruit trees are especially affected by iron deficiency. Apples, pears and plums do not set fruit well, give a meager, tasteless harvest. Vegetable crops often get sick, seedlings do not take root well in the ground and bear little fruit.

However, an excess of iron in the soil is just as dangerous as a deficiency. Signs of an excess of a microelement are:

• stopping the plant in growth;
• the color of the leaves becomes saturated;
• leaf cover crumbles;
• dark spots appear on the surface of the leaves.

It is important not to overdo it with feeding seedlings with microelements. Carefully follow the dosage of drugs indicated in the instructions.

Application norms

Vegetable crops - take 5 g per bucket of water, a liter of working solution is consumed per 10 square meters. The liquid is applied when the first four leaves appear on the seedlings. Then spraying is carried out after 2 weeks. Processing is carried out before the formation of buds.

Fruit plants are fed with the same working solution in a volume of 2 liters per square meter. Water fruit trees around the trunk when the first leaves appear. Then top dressing is carried out during budding.

Note! The dosage of the drug may vary, depending on the presence of additional substances in the solution.

Mode of application:

• processing of plants is carried out in the morning / evening in warm weather;
• the solution is used in sprayers, creating a cloud of spray;
• do not allow drops of the solution to roll off the leaves;
• Root top dressing is carried out on pre-moistened soil.

Spraying is usually used to prevent iron deficiency in plants. To do this, use either conventional spray guns or special sprayers. Healthy plants can be treated twice a season, diseased ones require more frequent spraying- 4 times.

Primary processing is carried out immediately after the unfolding of the first leaves, secondary - after 2-3 weeks. For vegetable and berry crops, a 4% solution is suitable, for fruit trees - 8%. For vineyards and ornamental plants use a 4% solution.

For root feeding, an 8% solution is used. Plants are watered with a solution under the root on previously irrigated soil. 1-2 buckets are spent per fruit tree, a couple of liters per berry bush, 4 liters per 10 m2 for feeding vegetable crops.

Can an overdose of iron chelate burn plant roots? A chemical burn is possible only if large doses of the drug are used.

However, the available form of chelated iron may become useless if there is a lot of chalk in the soil or the working solution has been in the open state for a long time.

Self-preparation of fertilizer

To prepare a working solution of iron chelate yourself, use a simple iron sulfate. Such a solution is no different from the purchased substrate, with the exception of the content of ballast substances. Therefore, it should be used strictly in the norm. The disadvantage of a self-made solution is the limitation in use: it is suitable only for preventive purposes.

Cooking method number 1

• 8 grams of vitriol is dissolved in two liters of warm water;
• 5 grams of citric acid are dissolved in the same volume of liquid, but in a different container;
• then you need to pour the vitriol solution into the citric acid solution in a thin stream with continuous stirring;
• at the end, pour into ready mix one liter of water, without ceasing to stir.

The result is 5 liters of working solution for plant treatment. It is impossible to store the finished liquid, it must be used up immediately. Make sure that the solution is clean, without any sediment. The color of the liquid should be orange.

Cooking method number 2

To do this, instead of citric acid, you should take pharmacy ascorbic acid. However, when buying, specify that the powder does not contain glucose additive.

• prepare a solution of ferrous sulfate - take 2 tsp of substrate per liter of water;
• add to ready solution 20 g of ascorbic acid;
• pour 3 liters of clean water, pre-boiled and cooled, into a container with a solution.

You will end up with a chelated iron solution ready to be sprayed. Keep in mind that the solution quickly forms a precipitate: use it immediately.

Characteristics of drugs

Ferovit is a universal photosynthesis stimulant. This fertilizer contains urea, nitrogen and chelated iron. The drug is intended for the treatment of all horticultural crops and ornamental plants throughout the year. Indoor flowers often suffer from hard water, which alkalizes the earth and creates obstacles for the free absorption of iron from the soil.

The use of Ferovit eliminates iron deficiency in the soil, promotes the rapid absorption of ions by plants, and nourishes seedlings. After applying the drug, the seedlings give friendly shoots, the ovary is actively formed on the fruit trees. Ferovit protects plants from rot damage, powdery mildew and brown rust.

Note! The chelated form of fertilizer is most suitable for summer plant nutrition: the substrate does not burn the roots and leaves.

For preventive treatment spraying is carried out. The solution is prepared from a liter of water and 1.5 ml of the drug. Fruit trees, berry bushes, vegetable and ornamental crops are sprayed at least three times per season (a break between treatments is 2 weeks). With a pronounced iron deficiency, the plants are treated every week until the green color is restored.

Processing indoor flowers and seedlings are carried out weekly - 1.5 mg of the drug is taken per 2 liters of water. Ground vegetables are treated every two weeks for prevention. Strawberry beds are sprayed with a solution of 1.5 mg per liter, the treatment area is 5 m2. Processing of bushes is carried out once with the growth of leaves.

The composition of the preparation Mikrovit K-1 contains sulfur, nitrogen and iron. This is very effective remedy to combat plant chlorosis. Microvit is used for foliar / root treatment of seedlings during the vegetative period. From a concentrated solution, you can prepare any required volume of working fluid. Citric acid is used as a chelating agent, which protects iron ions from oxidation.

Fertika preparation is a water-soluble granules and an aqueous solution. The granules are pre-dissolved in water, and then the seedlings are watered. Also, the granules can be scattered over the area and dug up. To fertilize seedlings, before transplanting into the ground, granules mixed with the ground are poured into each hole. When using granules, sufficient irrigation of the earth is necessary, since they release active substances only when moistened.\

Alternative

FeSO4 sulfate can be used instead of iron chelate. This substrate is much cheaper than chelate, but there is little benefit from it for plants. When ions decay most of useful substances disappear. In addition, the use of ferrous sulfate can lead to an overdose of sulfur and chemical burn plants.

Ferrous sulfate is ineffective on depleted soil and under adverse conditions. climatic conditions. It is also not effective to use this fertilizer in small areas (up to 12 acres and in greenhouses).

Iron chelate has become widespread due to its easily digestible form. These versatile and environmentally friendly fertilizers bring great benefit plants. Inorganic salts are poorly absorbed by the roots and leaves of seedlings, so the effectiveness of conventional agrochemicals is very low. Chelates are highly active, since trace element ions are in a biological shell.

Iron chelate eliminates such a common pathology as premature yellowing and wilting of plant leaves. However, the richest harvest from the site can be obtained by correctly combining mineral and organic fertilizers. Trace elements nourish plants with essential substances, and organic matter structures the soil and saturates it with humus.

One of essential elements necessary for the normal functioning of the body - iron. Girls and women of childbearing age especially need it because of monthly blood loss.

Until recently, it was argued that iron supplements should not be taken if there is no iron deficiency, tk. too much iron can be detrimental to health. However, the latest evidence is that it is desirable for girls and women of childbearing age to take iron at least during menstruation, which my daughter and I do.

The chelated form of any mineral is the most bioavailable and digestible, so I try to choose trace elements in this form. In this preparation, iron is in the form of bisglycinate - a chelate compound with glycine, which is perfectly absorbed and does not cause side effects eg constipation.
I often recommend raw whole food iron with vegetables and fruits, like Garden of Life, but it's quite expensive and not everyone can afford it. Therefore, such iron is a good alternative.

This preparation contains the daily norm of iron for women - 18 mg. Take 1 capsule daily after meals. Capsules standard size- 2 cm; easy to swallow. Childproof lid.

Before we started taking iron, my daughter had somehow reduced hemoglobin - 111 g / l, and she drank this iron for a month. The next analysis showed 127 g/L. In addition, she noticed that lethargy had passed, the brain began to work better.
My analyzes (once a year) now standardly show hemoglobin from 128 to 133 g / l.

It should be borne in mind that iron is better absorbed when there is a sufficient amount of vitamins A and C and copper in the body, but this does not mean that iron can be taken at the same time as multivitamins / minerals, because. it has poor compatibility with vitamin E and B12, calcium, magnesium, zinc, chromium. It is advisable to take iron separately, after another meal, for example, multivitamins / minerals after breakfast, iron after dinner. The main thing is that the above substances are present in the body normally.
