Changes in proteolytic and phosphatase activities of loamy dernopodzolic soil under the impact of Soligorsk potash plant

摘要

Alterations of proteolytic and phosphatase activities in the soil resulting from the impact of easily soluble mineral salts contained in potash plant tailings were studied. The results show that hydrolytic enzymes (protease and phosphatase) are verysensitive to increases in salt concentration in the soil. Inactivation of enzymes in the soil located 50 m from the source of pollution depends on both the salinization rate and the salt concentration.
