Influence of different plant protection systems on the chernozem enzymatic activity

It was studied the effect of chemical and biological plant protection products on the enzymatic activity of ordinary chernozem under chickpea crops. It was established that the activity of catalase and invertase decreases, and the activity of phosphatase increases when treated with chemical plant protection products. Biological plant protection treatments stimulate catalase activity and inhibit invertase activity, the activity of phosphatase remains at the same level.
