Abstract
This article presents the results of the physical and chemical properties of humic simple superphosphate obtained by decomposition of the ordinary phosphorous flour of the Central Kyzylkum with sulfuric acid and the addition of oxidized coal from the Angren deposit with hydrogen peroxide. The distinctive characteristics of humic simple superphosphate are shown in comparison with simple superphosphate obtained without the addition of oxidized coal.
