Application of amino acid chelated trace elements in new fertilizers
Zinc glycine chelate,manganese glycine chelate and copper glycine chelate are selected as donor materials for trace elements,adaptability tests are conducted on water-soluble fertilizers containing amino acids and macroelements,their stability is determined through cold and hot storage performance.After formula screening,zinc glycine chelate and copper glycine chelate show stable performance in the above two types of fertilizers,and the content reaches the expected level;However,manganese glycine chelate exhibits instability and precipitation in water-soluble fertilizers containing macroelements.In the field of new fertilizer processing,amino acid chelated trace elements can replace EDTA chelated trace elements to a certain extent with lower dosage and cost,it is recommended to promote the application.
