GO-Chelate granules – Cost effective WDG chelated trace elements for foliar application.
Micronutrients are supplied to the plants to prevent or treat deficiency symptoms. The simplest chemical structure is that of salts – inexpensive compounds but with a very limited efficacy because they are inhibited by the electrical charges present on the leaf surface or in the soil. For this reason, modern agriculture is now almost exclusively oriented on chelate complexes. They are suitable for foliar or root applications.
Microelements most commonly applied for root application is iron. The iron chelation is made with EDDHA-EDDHSA or similar compounds.
EDTA – the most common form of chelation.
DTPA – the most effective form of chelated iron, very expensive.
LS – the new category of lignosulfonates which show equal efficacy as the EDTA with no toxicity problem because they are natural vegetable products.
Many complex organic molecules exert a complexant action, and sometimes, even biostimulating: amino acids, humic and fulvic acids, seaweed are often used as natural complexants to enhance the penetration into the leaves.
