БОНИТИРОВОЧНАЯ ШКАЛА ПОЧВ ГОР И ПРЕДГОРИЙ ЮЖНО-КАЗАХСТАНСКОЙ ОБЛАСТИ

Abstract

With decreasing the height of the worsening conditions humification of the cold climate, and with decreasing altitude due to more arid climate is the oppression of vegetation and as a consequence of reduced reserves of humus. And therefore in the upper zone for soil formation in the limiting factor in thermal, foot - wetting. Thus, the most fertile are the mountain dark brown leached soils, up and down on that because of the limiting factors of head and moisture wits reduced bonitet score. Though the number of members on points bonitet and climatic factors on the properties of soil varies, but the average scores bonitet on the propertiesio Therefore, when developing bonitet scale for mountain and foothill soils, should be differentiated to take into account in addition to properties of soils and climatic factors.
