Compatibility of ‘soil-variety-fertilizer’ to fertilizer norms and dynamics of food elements

This article notes the geographical location and soil-climatic conditions of Kashkadarya province in Uzbekistan, as well mechanical composition, agrochemical properties dynamics nutrients soil field experiments conducted typical irrigated gray soils Shakhrisabz district. In total, 36% basin are soils, genetic layers studied area medium sandy, with large dust particles predominating fraction create nutritional regimens. driving humus 1.094%, total nitrogen 0.080%, phosphorus 0.168%, potassium 1.07%, mobile nitrogen, exchangeable belong to low moderately supplied groups. It is also possible fully demonstrate potential cotton by creating a scientifically based nutrient environment for promising variety “Porlok-4”.
