Abstract

In the study, the process preparation of phosphorus-humus fertilizers based on low-grade Central Kizilkum phosphorites activated using sulfuric acid in the ratio of 30-70% for decomposition of CaCO3 in the phosphorite followed by addition of activated sludge from municipal waster water was investigated.
