Intensive Environmentally Safe Fertilizer Application Cotton Research Soil Fergana Valley

Abstract

Plant nutrition depends on the soil moisture regime. Excessive moistening (at the PPW level) leads to irrational use of irrigation water and greater leaching of nutrients. Maximum nitrogen concentration in case of its concentration in the upper layer and penetration of 100 mm of precipitation into the soil is observed at a depth of 40 cm. A very small part of the applied nitrogen will remain in the arable layer, the rest will move to a depth of 70 cm.
