STRUCTURAL FEATURES OF TYPICAL CHESTNUT SOIL OF STEPPE ZONE OF KAZAKHSTAN

Tilepbergen Ryspekov

Abstract

The article shows features of a soil, illustrated with cracks. These cracks are natural detail of a soil, which more humified and less dense, than the rest part of the soil. Author highlights frequency and depth of these cracks in a soil profile, which essentially affects on the functions of the soil at the disclosure. On the mastered for an agriculture soil, cracks come from surface, in spite of that top horizons of the soil were homogenized in processing. Cracks go through the most humified part of the soil, which is the centre of пїЅtongueпїЅ and end in the deep of 65-70 cm as a narrow humified streaks. At the same time the main feature of these cracks should be considered, their infinite continuation in horizontal direction that was not highlighted in scientific researches. Difficult mechanical composition of the soil and climatic conditions of the zone in combination with cracks construction cause too big scope in yields of crops by years. On this base the work offers to pay attention at availability, sizes and allocation of soil cracks and a space between cracks. It will give new impulse for seeking ways of managing or crops yields forecasting in this subzone.
