Abstract

Inventia se refera la un îngrasamînt sub forma de granule constituit din 85...99% în greutate melamina cu dimensiunea particulelor sun 10 ochiuri/tol liniar si 1...15% în greutate ligand, ales dintre uree, sulfat de K, nitrat de amoniu, fosfat de amoniu, nitrat de K, clorura de K, lifnosulfonat de Ca, rasina ureo-formaldehidica, rasina melamina formaldehidica. procedeul pentru prepararea îngrasamîntului sun forma de granule consta în amestecarea melaminei cu ligandul, dupa care amestecul este contactat cu apa cu o solutie apoasa de ligad si, în continuare, amestecul umezit este aglomerat si uscat în final.
