CHANGE OF PHOSPHORUM AND EXCHANGE SODIUM CONDITIONS OF CHESTNESS SOILS UNDER THE INFLUENCE OF GRAZING

Аннотация

In order to prevent adverse anthropogenic effects on pastures in modern agricultural agriculture, an
adaptive strategy for further increasing food production and agricultural raw materials must be based on the
principles of environmental management, which includes a number of activities, the most important of which are
seasonality of pasture release taking into account the state of vegetation cover and its yield; determination of optimal
livestock load per unit area. The research aim is agrochemical assessment of grazing land cover depending on
grazing technology. As a result of the carried out studies, the negative influence of intensive grazing of farm animals
on the content of mobile forms of phosphorus and exchanged sodium chestnut types of pasture soils of West
Kazakhstan region was found. As a result of excessive grazing, the content of moving phosphorus of chestnut soils
decreased, the content of exchange sodium increased as part of exchange bases and non-salt soils became a medium
degree of salt content. The results of the studies confirmed the existence of a statistical pattern of reduction of mobile
phosphorus content and increase of exchange sodium content as grazing intensity increases across all soil types
