Микроморфологические свойства альфегумусовых почв северотаежной подзоны Западной Сибири
Soil-forming rocks rock of the territory being researched consists of layers of polymict sands which is distinctly visible in the soil profile of present-day soil. The prevalent components of the sandy rocks are minerals resistant to weathering, namely quartz and feldspars. One can observe a high co...
