ВЛИЯНИЕ АНТРОПОГЕННЫХ ФАКТОРОВ НА БИОЛОГИЧЕСКИЕ СВОЙСТВА ЧЕРНОЗЁМОВ СЕВЕРНОГО КАЗАХСТАНА

Abstract

Bacterial fertilizers, in part inoculant fertilizer, were not widely applied in the southern Kazakhstan because the conditions of their effective activity were not studied enough in local soils. It is known that the natural inoculation of nodule bacteria in plant root systems is not observed in all soils. In this case the root systems do not fulfill their function without inoculation and efficiency of legumes decreases. Thus, the selection of nodule bacteria active cultures and development of inoculant fertilizer supply legumes with biological nitrogen, increasing soil fertility and yielding ability. The total amount of soil microorganisms and enzyme activity of chernozems in North Kazakhstan was studied under minimum and zero tillage of soils.
