Abstract

See full text

This disclosure relates to slow- and controlled-release fertilizers (S-CRF), and more particularly to a microelement amino acid chelate-urea formaldehyde (UF) slow-release fertilizer and a method for preparing the same by reactive extrusion. The microelement amino acid chelate-UF slow-release fertilizer includes a biodegradable UF polymer and a microelement amino acid chelate. The macromolecular chains of the biodegradable UF polymer interpenetrate in the cross-linked network structure of the chelate, so as to form a polymer composite with a semi-interpenetrating network structure.
