Iron chelate solution preparation. Iron chlorosis of plants: all ways to combat iron deficiency

Material prepared by: Yuri Zelikovich, teacher of the Department of Geoecology and Environmental Management

Iron chelate is a modern, highly effective microfertilizer. Its action is specific, i.e. Iron chelate contains only one microelement, but it is very important - 2-valent iron ions Fe(II). Chelated iron treatment allows:

Quickly and without fear of overdose, treat non-infectious chlorosis (yellowing of leaves), even in a very advanced form. Plants, seemingly already dead, literally turn green again the next morning.
Even the most inexperienced gardeners can carry out preventive measures against chlorosis, see below.
Without fear of overfeeding with basic nutrients, intensify the photosynthesis of plants in unfavorable cultivation conditions - poor soil, lack or excess of light, cold, heat, dryness.

Microfertilization with iron chelate in combination with boron is especially effective for such demanding and highly soil-depleting crops as strawberries, radishes, etc. In this case, soil reclamation after them is simplified. Regularly treated with iron chelate along with boric acid strawberries, for example, produce stable yields on the same plot for up to 8 years in a row (!). Who knows what is commercial and simple good strawberries 3-4 years after planting it needs to be rejuvenated and replanted in another place, it’s unlikely that you’ll just believe it, but try it, at least on a dozen bushes to begin with. How iron chelate is used with boron for strawberries, see the video below:

And why?

Iron chelate is especially good for small areas, 6-40 acres. Here he is in capable hands may turn out to be a truly miraculous remedy. Why is that? What kind of panacea is this?

Iron chelate for plants is an ideal supplier of Fe(II) necessary for the synthesis of chlorophyll. In fact, iron in the soil is always in abundance, or even in excess, but 3-valent Fe(III), which forms the well-known hydroxide - rust. Fe(III) is of little use to plants and can even be harmful; Fe(II) is required to produce chlorophyll. This is explained by the fact that Fe++ iron ions migrate much more actively and faster in plants. But 2-valent iron very readily transforms into 3-valent iron, especially in the presence of oxygen and hydroxyl ions OH–. In chelate form, Fe(II) can remain in principle for an unlimited time; realistically - until the chelate complex itself disintegrates, see below. And what is especially important for plant growing is that under natural conditions, chelates decompose approximately at the rate of Fe(II) absorption by plants. That is, iron chelate feeds plants with Fe(II) just in moderation, “according to appetite.” This is a common property of all chelated fertilizers, see also at the end.

Note: the disintegrated chelate complex does not provide ballast, because in its composition, in addition to iron, it contains carbon, oxygen, hydrogen; sometimes nitrogen. The breakdown products of the chelate shell are carbon dioxide and water, which are not harmful to plants and do not pollute the soil.

What are chelates

Chelated iron is a Fe++ ion “packed” into a ligand shell of weak organic acid residues, on the left in Fig. Fe++ is mainly used for chelation lemon acid. There is no covalent bond between Fe++ and the elements of the ligand, therefore the iron ion in the chelate cage retains its valence until the ligant disintegrates: the chelate shell does not allow negative ions and active molecules capable of converting iron into the Fe+++ form. But the positive charge of Fe++ is enough to neutralize the weak acidic properties of the ligand, so it is difficult to chemically burn plants with an overdose of chelates: you literally need to flood the plants with the working solution. Then the negatively charged residues of the decaying ligands will have time to burn the plants before they completely disintegrate, but if the processing conditions are met (see below), this is excluded.

Forms of release and working

In the form of powder and other pure solid forms, iron chelate is unstable in air and light, so it goes on sale either in the form of tablets with binders and stabilizers, or in bottles with a concentrated mother solution, in the center in Fig. Both can be stored in their original packaging for up to a year. Opening the package does not reduce the shelf life if it was immediately sealed after selecting the portion. Iron chelate stock solution (which you can make yourself, see below) is a dark brown liquid (right in the figure); worker - light brown or orange. The mother liquor in a covered (not hermetically sealed) or not completely filled large container, e.g. plastic bottle, stored for 2 weeks; the working solution must be used immediately.

Chelate or sulfate?

An alternative supplier of Fe(II) to plants is iron (II) sulfate FeSO4. Its advantage is considered to be low cost, but in reality this is not the case:

Iron (II) sulfate is often confused by uninformed buyers (and sellers) with ferrous sulfate (III) (Fe)2(SO4)3 - ferrous sulfate. It is iron (III) sulfate that is several times cheaper than the chelate, but it is also much less useful to plants than it is dangerous: during the decay of (very slow) (Fe)2(SO4)3 ions, Fe++ is formed in an amount that is negligible even by the standards of microfertilizers, and highly active SO4++ ions are very capable of harming plants. As for FeSO4, it is much more expensive than iron (III) sulfate;
The rate of Fe++ release during the decomposition of FeSO4 does not correspond to the rate of absorption of 2-valent iron by plants, therefore most of the active substance from FeSO4 is lost;
FeSO4 as a fertilizer produces a lot of sulfur ballast - much more than the sulfur plants need, therefore, with an increase in the dose of iron (II) sulfate as a fertilizer, plants are poisoned with sulfur, and in combination with point 1, also a chemical burn;
Iron (II) sulfate, unlike iron chelate, is ineffective for plant nutrition on poor soils, in summer and in difficult weather conditions.

Ultimately, it turns out that, if recalculated by the amount of active substance absorbed by plants, then when manually processing small areas, the iron chelate turns out to be cheaper iron(II) sulfate. Especially if a homemade working solution is used, see below. The only possible exception is the treatment of an adult garden that has reached stable fruiting with an area of 10-12 acres experienced gardener who know how to spray tree crowns in hot weather. Treating vegetable gardens up to 12 acres and greenhouse crops with iron chelate is definitely more profitable than iron (II) sulfate.

Application

The use of iron chelate in gardening and gardening due to its low danger to plants is not difficult and is carried out simply according to the schedule: vegetables are sprayed with a 0.5% solution (5 g per 10 liters of water) at the rate of 1 liter per 10 square meters. m of green area in the phase of 3-4 true leaves and after 2 weeks or, for those flowering during the growing season, at the very beginning of budding. Fruit trees are watered with the same solution, 2 liters per 1 square meter. m of the trunk circle at the beginning of leaf blossoming and also at the beginning of budding, because Treatment of trees with iron chelate along the crown is less effective due to their different physiology compared to herbaceous ones. Emergency treatment for the treatment of chlorosis of vegetables and fruits is carried out by spraying with a 1% solution at double the rate.

Note: In the instructions for use of tablet and liquid branded iron chelate, you can find other dosages. This is explained by the presence of ballast substances in tablets or solvent. If recalculated to active substance, the concentration will be the same.

Iron chelate is a substance of the 3rd class of danger for people, so it must be processed using PPE. The rules for spraying and feeding the roots are common for microfertilizers:

Spraying and watering are carried out in the evening; preferably in warm cloudy weather.
The sprayer should produce a misty drizzle without clearly visible spray.
Treatment of the next area is stopped when the smallest dew settles on the leaves; the appearance of rolling drops is unacceptable.
Feeding watering with iron chelate is carried out on previously well-moistened soil.

DIY iron chelate

You can prepare a working solution of iron chelate yourself from cheap iron sulfate. IN in this case the fact is used that during the dissociation of iron sulfate in an aqueous solution, Fe++ ions are partially formed, which are immediately captured by the chelating agent; it is not greedy for Fe+++ ions. The working solution is as effective as the one made from purchased reagents, but contains quite a lot of ballast, so treatment with it must be carried out exactly according to the norm, and it is not suitable for the urgent treatment of chlorosis, but is quite suitable for preventive fertilizing. A homemade working solution of iron chelate is prepared. way:

In 2 l warm clean water(preferably distilled) dissolve 8 g of iron sulfate;
In a separate bowl, dissolve 5 g of citric acid in the same amount of water;
A solution of iron sulfate is poured into a solution of citric acid in a thin stream while stirring;
Also pour in another 1 liter of clean water in a stream while stirring.

This yields 5 liters of a 0.5% solution, which should be used immediately. An indicator of the suitability of the working solution for use is transparency (there should be no sediment or turbidity) and orange color. Dilute ready solution it is forbidden; if more is needed, increase the initial amounts of water and reagents.

Note: If plants show signs of copper starvation, copper chelate will help quickly correct the problem. It is prepared in the same way, you need 20 dry ingredients copper sulfate and 40 g ascorbic acid.

More about chelates

More or less experienced plant growers know that summer feeding is a rather complicated matter - due to weather conditions, plants can be easily overfed or burned. Therefore, leading manufacturers of agricultural chemicals for small farms produce special summer fertilizers in chelated forms, see e.g. track. video.

Plants require a variety of beneficial microelements for normal growth. The most important means for vegetation is iron chelate. Its use is largely to prevent chlorosis. Throughout the life of plants, the need for the substance does not go away, but may change somewhat; accordingly, the dosage should be regulated and selected individually.

Features and positive qualities of iron chelate

Before considering iron chelate, you should learn more about iron, what it is. Iron is an active component; it is necessary for vegetation to live, as it acts as a stimulator of metabolic processes. It is also important for plants because it actively participates in the release of chlorophyll, and, accordingly, respiration.

What is the chelated form? Chelated iron is a Fe++ ion that is located inside a ligand shell consisting of large quantity organic acid residues. Citric acid is often used to achieve chelation. Due to the presence of the shell, foreign ions and molecules that can change the shape of Fe++ do not penetrate into the substance.

Iron chelate for plants

This microfertilizer is iron in chelated form, that is, a complex compound of iron ions with amino acids. This form of the substance is especially useful for plants, as it can be fully absorbed. The presence of the component provides high-quality nutrition for the healthy development of the plant. Its amount is somewhat smaller than macroelements, but exceeds various microelements. Due to the need for a large amount of the substance, chelated iron becomes indispensable for the gardener.

A deficiency of iron chelate will lead to a noticeable deterioration in the condition of the plant; it may be susceptible to chlorosis. A pathological change in the metabolic function of a plant is associated with a violation of chlorophyll synthesis in the foliage. The most characteristic manifestation is excessive lightness of the leaves and noticeable green veins on them.

Plants need iron in a chelated form of fertilizer, otherwise an acute deficiency of the substance develops, which leads to chlorosis. The problem is solved by feeding with chelate complexes.

You can determine that plants require iron chelate by the following characteristic features:

young leaves begin to turn yellow and green streaks characteristic of diseases appear;
leaf sizes decrease;
flowers, ovaries or foliage fall off without noticeable external reasons;
flowers grow, but have an irregular shape;
the growth of the rhizome system stops, and as the disease develops, it dies;
the development of greenery and tops stops;
The edges of the foliage have a curled shape.

Plant fertilizer microelement Iron Chelate

If the listed symptoms are detected, perhaps not all at once, it is worth treating the disease with the help of chelated fertilizers.

Iron chelate has many advantages:

absolutely non-toxic;
can be combined with other mineral-type preparations;
easily dissolves in water and leaves no sediment;
easily assimilated by all cultures;
resistant to harmful and beneficial microorganisms;
has high transportation rates; when it penetrates the foliage, it is quickly distributed throughout the entire stem and rhizome;
can be used together with pesticides;
universal, as it can be used for foliar and root feeding.

It is important to remember that if there is an excessive amount of chalk or dolomite impurities in the soil, iron can become completely useless, since it will not be absorbed by plants. In this condition of the soil, it will be extremely difficult for plants to cover the deficiency in iron chelate.

Chelated fertilizers can become unusable through the oxidation process, which is activated by a reaction with oxygen. It will be impossible to restore the component's usability after this.

Effect of the drug on indoor plants

Iron chelate for indoor species Plant management is especially important, since a small amount of soil often results in a deficiency of useful microcomponents. Due to lack various substances the flower gets sick and sometimes dies. Chelated fertilizers are especially important for the following plants:

citrus;
gardenias;
hydrangeas;
azaleas;
clerodendrums.

Chelate complexes are important for them, since a deficiency acutely affects the condition of plants. Most flower growers know this feature of the listed varieties, and even before the onset of disease symptoms, they carry out regular feeding.

The instructions for using the drug contain recommendations regarding preventive measures for feeding the plant with iron. With a sufficient amount of microelements, flowers and other plants are characterized by rapid development and high level natural immunity to stressful conditions and the disease chlorosis. Even after the onset of the disease, the plant can be cured, but you cannot delay feeding, otherwise you may be late.

Iron chelate for indoor plants very important

Application on various types of soils

Instructions for use and reviews indicate that fertilizers perform well in various types soils and climatic zones. For soil with an excess amount of carbon, such an additive is the only effective microfertilizer.

When comparing the effectiveness of the influence on different types of soil, the product is significantly superior to other types of microelements. The gap in performance between the compared groups reaches 200–1000%.

Applications of Iron Chelate for Plants

The use of iron chelate varies greatly depending on the expected effect and the reason for use. Depending on whether the drug is used for plant prevention or restoration, the dosage, fertilizer application interval and application period may differ.

For retail buyers the store sells fertilizer in small packages or you can prepare the product yourself

Prevention

The drug should be diluted in a concentration of 5 g per bucket of water. After obtaining a homogeneous solution, spray the green part of the plant. It is recommended to carry out treatment at least 2 times. You can use the drug for the first time after throwing out the first leaf, and you should continue the procedure throughout the entire growing season. It is preferable to maintain an interval of 2 weeks between sprayings.

IN last time Treatment must be carried out even before the plant blooms. The consumption of the drug is 1 liter per 10 m2.

Microfertilizer Iron Chelate

To treat plant diseases, it is worth doubling the dosage to 5 g per 5 liters of water - the concentration applies to all fruit trees. All other crops require the use of a solution of 5 g per 8 liters of water. After preparing the mixture, you should generously spray all the greenery of trees or plants.

Number of treatments 2 per month at regular intervals. To achieve a positive result, it is worth performing the procedure at least 4 times.

To enhance medicinal properties drugs required for advanced forms of chlorosis can be carried out root feeding. To top up, make a solution of 5 g per 5 liters of water and cover the ground with the substance; 2 liters of liquid are used per 1 m2.

The drug is relatively safe and practically incapable of causing harm to humans, but before use you should take care basic rules personal safety:

use rubber gloves before processing;
after spraying or topping up, be sure to wear a change of clothes;
You should wear protective gear on your head; a scarf, cap, etc. will do;
be sure to protect your vision and respiratory organs by wearing a gauze bandage and safety glasses - this is important when spraying the substance;
After finishing the procedure, you need to wash your hands, face and open areas skin using a soap solution under running water;
If the substance gets on the mucous membranes, you should immediately rinse with plain tap water.

To save useful properties The substance must be stored in a dark place, out of reach of children. Recommended temperature – from 0 °C. The storage duration is not limited provided the above conditions are met.

Treatment of chlorosis with iron chelate

Making iron chelate at home

Making fertilizer is possible with your own hands; this does not require special qualifications or special tools. At self-cooking you can save a significant part of the cost compared to purchasing a ready-made drug.

There are 2 main methods for preparing the drug yourself, and both require . You will have to buy it, but the cost of the product is significantly lower than ready-made fertilizer.

First way

To prepare iron chelate, you will need to buy ascorbic acid, it is sold in all pharmacies and is inexpensive. It is important to clarify the absence of glucose in the composition; a product with glucose will not be suitable for the task.

Cooking algorithm:

Prepare a solution of iron sulfate according to the instructions. Add 1 tsp to the mixture. vitriol per 500 ml of liquid.
Add 10 g of ascorbic acid to the prepared composition.
Add 3 liters to the mixture boiled water. After thoroughly mixing all the ingredients, a ready-made solution is obtained.

The dosage of homemade iron chelate is approximately 0.5%. This concentration is optimal for spraying plants.

Making iron chelate at home

Second way

In this option, ascorbic acid will be replaced by a more accessible substance - citric acid, which is sold in most grocery stores. To prepare the working composition you should:

Prepare 3 liters of boiled water.
Add 1 tbsp to the jar. l. acids.
Then add 1 tsp. vitriol.
After thorough stirring, you should get a liquid with orange, it is already ready for use.

The properties of homemade chelated iron are practically not inferior to purchased options, but the storage of the substance is significantly reduced. Ferum is prone to oxidation and precipitation, rendering the liquid useless after a few days of waiting.

Methods of application

In the instructions for the substance there are 2 main ways to use the drug: foliar and root. Foliar spraying is predominantly used; this method is sufficient for most purposes. The use of root feeding is justified only in cases of advanced forms of chlorosis, when the concentration of the substance is insufficient.

Main methods:

foliar treatment is spraying the foliage of trees or plants using a spray bottle. For healthy plants It is worth carrying out 2 treatment procedures for high-quality prevention. When chlorosis develops, the plant is coated with iron chelate 4 times. The first treatment is carried out after throwing out 1 leaf, then with exposure for 15–20 days. A concentration of 0.8% is suitable for fruit trees, and 0.4% for others;
For root feeding, a solution at a dosage of 0.8% is used. It is poured under the rhizome of the plant; it is better to prepare the holes so that the liquid does not spread. For 1 tree add 1–2 buckets, for 1 bush – 1–2 liters, at full coverage– per 100 m2 use 4–5 liters.

Chelated iron is the key to high-quality plant development and protection against chlorosis. Making your own can save time and money. Due to its low cost, safety and ease of use, the product is well suited for beginning gardeners.

For normal growth, plants need nutrition rich in useful elements. One of these is iron chelate - an indispensable microfertilizer for plants biologically. active form. Among Ukrainian manufacturers, the leading company in the production of chelate fertilizers and their first developer is SPC "REAKOM".

Features of using iron chelate for plants

There are three possible ways Applications of iron chelate: root tillage, drip irrigation And foliar feeding plants. Best result gives precisely the foliar method of applying microfertilizers containing iron.

When used, iron chelate demonstrates a number of positive qualities:

Non-toxic.
Completely soluble in water and easily penetrates foliage.
Compatible with mineral fertilizers and pesticides.
Universal in use.

The effect of regular use of iron chelate is as follows:

Elimination of iron deficiency.
The emergence of immunity to diseases in plants.
Improving photosynthesis and plant respiration.
Normalization of metabolism.
Stimulation of plant growth and development.
Ensuring sufficient presence of chlorophyll in leaves.

Instructions for use of iron chelate for plants

The proportions, time intervals and duration of use of iron chelate depend on the purpose for which the drug is chosen: preventive or therapeutic.

For the purpose of prevention

Feeding plants with iron chelate will not be superfluous if the plant does not have any visible signs of disease.

In this case, it is necessary to measure out 5 g of iron chelate and dissolve it in 10 liters of water. Treatment with the prepared solution is carried out once every 2 weeks by spraying the foliage throughout the growing season. Preventive treatment can begin from the moment the first leaves appear, and should be completed before flowering begins. During this time, spraying should be carried out at least 2 times at a consumption rate of 1 liter per 10 square meters. m.

In the treatment of chlorosis

Chlorosis, caused by a lack of iron, manifests itself in plants in the form of the following symptoms:

yellowing of the leaf blade with the appearance of green veins;
reduction of leaves in size;
delayed development of shoots;
causeless falling of leaves, flowers and buds;
deformation of inflorescences;
curling the sheet along the edges.

If at least one of the listed symptoms of the disease is detected in a plant, it needs treatment.

For this purpose, it is necessary to dilute 5 g of the drug in 5 liters of water (for fruit trees) and 8 liters of water (for all other types of crops). The foliage is sprayed with the resulting solution once every 2 weeks at least 4 times during the entire cycle. In case of pronounced chlorosis, the effect can be enhanced by root application of iron chelate, for which 5 g of the drug is diluted in 5 liters of water. at the rate of 2 liters per 1 sq. meter.

When working with iron chelate, it is important to follow safety rules: spray with gloves, safety glasses and a gauze bandage. If the solution gets on your skin or eyes, rinse them with water.

I'll share mine with you excellent result in treatment iron deficiency :).

Brief Introduction

In 2015, I discovered that I was anemic. I had terrible weakness, it was very difficult to think, my hair was falling out. After reading a lot of information on the Internet, based on the symptoms, I began to suspect that I had anemia. As a result, I found out that the most informative analysis is ferritin, the iron depot in the body. I took this test in the laboratory and my result was 20 ng/ml, while 70 ng/ml is considered normal.

I wrote in detail about anemia and iron deficiency - signs and symptoms, test results, types of iron supplements, dosages, nutrition and much more in my old blog in a series of articles:

The story continues

So, since 2015 I have been with with varying success treated iron deficiency. The maximum indicator that I managed to achieve in 4 months of continuous use of the pharmaceutical drug ferric iron Maltofer, 3 tablets per day, was the indicator 56 ng/ml. After stopping or if I only took 1 tablet as a maintenance dosage, my ferritin level dropped back to about 30 ng/ml .

Then, after a question from a reader of my blog, I researched information about very good medicine iron - iron protein succinylate and then bought it. However, due to high cost I couldn’t take it for long and switched to Maltofer again with the same insufficient results.

In the end I got tired of it and decided to try it chelated iron (glycinate chelate). I thought that in terms of price-quality ratio, it would probably be the best.

I researched the options on iHerb and ordered a large 250-tablet bottle from Carlson Labs, intending to take it long-term.

(if Carlson Labs is not available, see links to similar dietary supplements below in the text)

Before you start taking chelated iron I specifically took the test for ferritin to accurately track the dynamics in a month. My indicator was 31 ng/ml .

A month later, I stopped taking it and waited a week, as indicated in the laboratory’s recommendations, I wrote about this in an article, and took the test again. I was very surprised - my ferritin test result was 64 ng/ml ! I've never had anything like this. And it’s only been a month and such a great result! 🙂

Now I’ll tell you in more detail - chelated iron I took 3 tablets per day. I took 3 at a time, because I take a lot of other dietary supplements, and iron cannot be combined in one dose with zinc and magnesium.

Dosage of 1 tablet Carlson Lab - 27 mg of iron, that is, in I took 81 mg daily, which is consistent with the dosage indicated in scientific articles O various types gland.

« 80-100 mg iron per day for women who have ferritin<30 µg/l;
40 mg iron per day, women with ferritin 31-70 µg/l;
40 mg iron per day for women with ferritin < или = 70 µg/l.
Women with ferritin > 70 µg/l dont need in an iron supplement."

I took 81 mg, since at the beginning of treatment my ferritin was 31 ng/ml. Don't be confused by different units of measurement, because µg/l = ng/ml.

Chelated iron is well tolerated - without the slightest discomfort for the stomach and intestines. I can say this for sure, since my gastrointestinal tract is sensitive.

I'll take a little more iron to get to 70 ng/ml and then only take it a few days a month after my period to replace blood loss.

I also provide links to similar dietary supplements of chelated iron in the same dosage (25-27 mg) from good manufacturers:
Solgar, Iron Chelate, 25 mg, 100 Tablets

Bluebonnet Nutrition, Extra Strength Chelated Iron, 27 mg
Thorne Research, Ferrous Bisglycinate, 25 mg

And in this version, the increased dosage in 1 tablet is 50 mg. Keep this in mind when calculating your dosage.
Solaray, Iron, 50 mg

And now a little more about chelated iron

Iron chelate is a combination of iron ions with an amino acid, usually glycine. "Chela" is translated from Latin as "claw". In a chelate compound, the iron atom is connected to amino acids, as if taken in a claw.

Chelated forms of minerals are considered the most effective and at the same time gentle - without side effects.

Concerning effectiveness of chelated iron I will provide information from scientific research.

Children aged 6 months to 3 years took ferrous sulfate and ferrous bisglycinate chelate. The difference in serum ferritin concentration was significantly greater in the group that received ferrous bisglycinate chelate.

Another study compared the tolerability of ferrous sulfate and ferrous bisglycinate chelate. Both ferrous sulfate and ferrous bisglycinate chelate were found to have equivalent therapeutic efficacy at a similar dose (50 mg), but side effects were higher (37% vs. 21%) in the group receiving ferrous sulfate.

Iron bisglycinate chelate, due to its chemical structure, can be partially resistant to the action of enzymes and the binding of substances present in food, such as metals, dietary fiber, phytates and phenols, with which iron can form insoluble compounds.

In addition, due to the binding of amino acids, there is less direct exposure of iron to the lining cells of the gastrointestinal tract. This may reduce toxicity and side effects affecting the gastrointestinal tract such as constipation, nausea, diarrhea and vomiting.

Considering this information and my experience, I conclude that chelated iron is an effective and safe drug for the treatment of anemia and iron deficiency.

A complex organic microfertilizer containing iron in chelated form is called iron chelate. It is effective means to combat lime (iron) chlorosis of agricultural plants. The drug is used for treating open and greenhouse soil as root feeding, as well as for foliar treatment of vineyards, vegetable and fruit crops.

Fertilizer is a combination of 2-valent iron metal ions F (II) with two or more free neutral organic atoms.

This symbiosis is ideal for the intracellular transport of iron ions through the biochemical barriers of any plant.

The main advantages of iron chelate include:

Chelator applied to the soil for a long time remains available for absorption by the root system. After three days of active interaction with plant cells, metal cations pass into tissue metabolites, significantly enhancing the process of photosynthesis.

Compounds in chelated form are much more stable than trace elements in the form of inorganic salts.

Most effective and accessible to plants concentrates of the following metals polychelated with amino acids:

iron;
copper;
manganese;
zinc.

Plant fermentative systems cannot function without iron. The lack of this microelement inhibits the conversion of carbon dioxide into organic substances, making oxidative and energy processes that precede the formation of chlorophyll impossible. And as a result, the growth and development of the vegetative mass of agricultural crops slows down.

Plants need on average from 0.6 to 9 kg/ha of iron oxide (its formula is Fe203).

Basically, the soil contains a sufficient amount of this element - about 4%, but the form is sparingly soluble useful substance is absorbed very poorly.

Iron deficiency is especially common in carbonate, lime-rich soils.

The most sensitive crops to the lack of this microelement are: corn, grapes, potatoes, carrots, tomatoes and cucumbers, cabbage, raspberries, citrus fruits and all garden trees.

When destroyed, chlorophyll makes green leaf pale, light yellow with a cream tint. In this case, the leaf veins may not change color. These symptoms appear on the upper young shoots. Lower leaves still remain green, and the inflorescences become underdeveloped and small.

With significant iron deficiency the plants stop growing and bearing fruit, and after a while they die.

Such signs are characteristic of a disease called calcareous chlorosis.

For the purpose of treatment and prevention of microelement deficiency - F (II) in horticulture and agriculture The drug used is iron chelate.

For plants, according to the rules of agricultural technology, fertilizing with which fertilizer is mandatory and is carried out with at certain intervals. This allows:

In a short time, without fear of overdose, treat iron chlorosis even in very advanced cases. Discolored plants treated with the drug in the evening gradually begin to turn green in the morning.
Even novice gardeners and gardeners can prevent the appearance of chlorosis in their plantings by using preventive treatments.
Increase plant immunity and increase their productivity, despite unfavourable conditions growing - poor soil, extreme temperature regime, lack of sunlight or drought.

The effect of this microfertilizer is enhanced in combination with boron for such capricious and significantly depleting crops as radishes and strawberries. And the process of soil reclamation after them becomes less expensive.

Foliar feeding is indispensable in modern technologies growing. On quality soils, when the yield can be affected by the absence of just a few macro or microelements, foliar feeding the best option application of fertilizers.

Antichlorosin (iron chelate) is ideal for this method of treatment.

Instructions for use by spraying:

The same proportions of the initial solution are used for root feeding.

The amount of solution for preventive treatment will be:

watering - 2 liters per 1 sq. m.;
spraying - 1 liter per 10 sq. m.

And, accordingly, for medicinal purposes the consumption and concentration will be 2 times greater.

Precautionary measures

Fertilizer, if it gets on the skin, may cause irritation in people sensitive to such substances. Therefore, using the drug must be adhered to general rules security:

work only in protective gloves, a change of clothes and a hat;
spray while wearing safety glasses and a gauze bandage;
If the drug gets on the skin of the face or in the eyes, rinse with plenty of clean water;
After finishing processing the plants, wash your hands with soap.

Shelf-life Unlimited.

When there is no ready-made preparation at hand, we can make iron chelate with our own hands. The plant is sick and needs to be saved urgently, for this we take:

1 liter of rain or distilled water;
2.5 g citric acid;
4 g of iron sulfate.

We dilute the vitriol and acid in separate containers and pour the vitriol into the citric acid solution.

Stir until smooth. The solution is ready.

We obtain iron chelate at a concentration of 0.5 g/l.

Or we can use 20 g of ascorbic acid per 10 g of iron sulfate.

Cook using the same technology until all components are completely dissolved.

This is how you can make chelated iron at home. and obtain a solution suitable for one-time processing. The mixture cannot be stored for long periods of time.

A large number of positive reviews about this fertilizer confirm its effectiveness and indispensability in the fight against chlorosis. The drug helps to wait out unfavorable weather with minimal yield losses and at the same time stimulates the development of stable immunity to various external factors in plants.
