Abstract
Based on the determination of adsorption and equilibrium concentration of phosphorus in irrigated typical gray soils using the Nair method, the standard soil requirement for phosphorus was determined. The influence of the norms of mineral and organic fertilizers established on the basis of standard soil needs and phosphorus consumption on the formation of the planned crop on the absorption of basic nutrients, distribution on vegetative and generative organs, on the formation of a crop unit and cotton yield has been established.
