NOVEL TYPE OF PHOSPHORUS-HUMIC FERTILIZERS BASED ON LOW-GRADE KARAKALPAK PHOSPHORITES

Abstract

In this article, composts are prepared based on manure and phosphorite at mass manure ratios: phosphorite (from 100 : 5 to 100 : 30). Water was added to the prepared mixture based on the calculation to achieve 70% moisture content. It was determined the kinetics and degree of organic part transformation of manure into humic substances and indigestible phosphorus forms into a form assimilable for plants in slime phosphorite.
