Effects of phosphogypsum on enzyme activity and microbial community in acid soil.

ABSTRACT: Phosphogypsum (PG) is a solid waste produced from decomposition of phosphate rock in sulfuric acid. It can improve the physicochemical properties of soil. However, the application of PG will inevitably change the living environment of soil microorganisms and lead to the evolution of the soil microbial community. The effects of PG (0, 0.01%, 0.1%, 1%, 10% PG) on soil respiration, enzyme activity and microbial community were studied systematically by indoor incubation experiments. The results showed that the addition of 0.01% PG had little effect on the soil physicochemical properties and microflora. The soil respiration rate decreased with the increase of PG; The activities of catalase, urease and phosphatase were decreased and the activities of sucrase were increased by 10% PG treatment, w
