MINERALOGICAL COMPOSITION OF THE SIEROZEMIC SOILS IN THE FOOTHILL PLAINS OF ZHETISU RIDGE
Abstract
The mineralogical composition of the fine dispersed part of soils of the foothill plains of the Zhetysu Ridge was studied for the first time as part of the assessment of the fertility and current state of soils of agricultural lands of South-Eastern Kazakhstan. For the first time, studies of clay fraction of northern sierozems showed the following mineral composition: mixed -layer illite-smectite formations, hydromica, kaolinite, chlorite, lizardite, and non-clay minerals -highly dispersed quartz and feldspars; meadow-sierozemic soils contain: mixed-layer formations, kaolinite, lyzordite, magnezioarfvedsonit, mica, chlorite, quartz and feldspar.
