 abstract={Intensive penning-up sheep considerably modifies chemical properties of soil. Physical degradation and an increase in the content of mineral N and available K to a toxic level account for the destruction of turf. High concentrations of N and K are maintained for several weeks after penning-up sheep and they decrease only with an increase in plant production. Insignificant vertical and horizontal movements of soil elements were observed. The possibilities of movements were different for different elements. The rhythm of biological changes after penning-up sheep was closely related to the dynamics of chemical modifications in soil.},
