RESULTS OF MONITORING АГРОХИМИЧЕСКИХ OF PROPERTIES OF ORDINARY SOLONETZIC CHERNOZEMS OF KURGAN AREA
The article considers the changes of agrochemical properties of ordinary saline black soils in Kurgan region under conditions of different levels of crop cultivation. It has been proved that humus decrease in agroecological systems is characteristic for humus dynamics. It is less under conditions of moderately intensive technologies on experimental plots than under conditions of extensive technologies in the production fields.
