    Iron chelate instructions for use


    Physical and chemical characteristics of iron chelate


    This is a microfertilizer containing iron in a chelated form in an amount of 25–30 g / l. The pH is close to neutral (6–8).


    Iron chelate is a coordination compound of an iron ion with two or more donor ligand atoms (neutral molecules). < When a concentrated solution of a chelate is introduced into highly concentrated solutions of mineral fertilizers (usually such solutions are used in hydroponic cultivation), precipitation of the chelate is observed.


    The stability of the iron chelate depends on the acidity (pH) of the medium. At pH <2 (acidic solutions), it can break down and turn into soluble inorganic salts. At pH> 9 (alkaline solutions) it also decomposes with the conversion of cations into practically insoluble hydroxides.


    Iron chelate decreases concentration when exposed to light and when exposed to ultraviolet radiation.


    Behavior in soil


    Iron chelate as a complex organic compound, when introduced into the soil, remains in a mobile (assimilable) state for a long time.


    Through the root system and leaves, the chelate can enter the stem and leaves without changes, but after 1–3 days it is destroyed with the transition of the metal cation to the metabolites of plant tissue.


    Separation of chelated forms of iron may be observed in the soil before absorption, which accelerates the recovery of Fe 3+ to Fe 2+ on the surface of the roots, which usually absorb the Fe cation 2+ .


    Methods introduction


    Treatment of plants with iron chelate is performed during root and foliar treatment of plants. Maximum efficiency, especially when treating plants with chlorosis, Iron chelate is obtained by reacting an iron salt with a complexing agent in an aqueous medium: N, N, N ', N'-ethylenediaminetetraacetic acid and citric acid. Acids are introduced simultaneously or sequentially at a temperature of 70–90 ° C.

    Simultaneously with the complexing agent or after it, an aqueous solution of ammonia or ammonium citrate is added to achieve a pH of 2.0–2.3. The complexing agent can be supplemented with succinic acid. This method allows you to obtain a product in the form of a concentrated solution containing up to 100 g / l of iron.
