Is Composting a Route to Solubilize Low-Grade Phosphate Rocks and Improve MAP-Based Composts?

ABSTRACT: In alkalinized and Ca-rich composts, solubilization of apatite from phosphate rocks (PRs) is not guaranteed; however, chelating agents and humified substances produced during composting may alter the soluble contents and P forms of monoammonium phosphate (MAP)-based composts. These effects...
