Iron and ligand are absorbed separately by the plant roots whereby the highly stable ferric chelate is first reduced to the less stable ferrous chelate. [6] In horticulture, iron chelate is often referred to as 'sequestered iron' and is used as a plant tonic, often mixed with other nutrients and plant foods (e.g. seaweed).
The Andersons PGF Complete Lawn Fertilizer 16-4-8. According to the manufacturer, a year of researching and testing lent itself to this fertilizer which combines other top products plus all the ...
Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2.This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH.
Iron can be made available immediately to the plant by the use of iron sulphate or iron chelate compounds. Two common iron chelates are Fe EDTA and Fe EDDHA. Iron sulphate (Iron(II) sulfate) and iron EDTA are only useful in soil up to PH 7.1 but they can be used as a foliar spray (Foliar feeding). Iron EDDHA is useful up to PH 9 (highly ...
DTPA under the form of iron(II) chelate (Fe-DTPA, 10 – 11 wt. %) is also used as aquarium plants fertilizer. The more soluble form of iron, Fe(II), is a micronutrient needed by aquatic plants. By binding to Fe 2+ ions DTPA prevents their precipitation as Fe(OH) 3, or Fe 2 O 3 · n H 2 O poorly soluble oxy-hydroxides after their oxidation by ...

EDDHA or ethylenediamine-N,N ′-bis(2-hydroxyphenylacetic acid) is a chelating agent.Like EDTA, it binds metal ions as a hexadentate ligand, using two amines, two phenolate centers, and two carboxylates as the six binding sites.
