Phosphate Regime of the Gray-Brown Soils of the Absheron Under the Vineyards Depending on the Application of Various Types and Doses of Fertilizers
The presented article discusses the results of the use of organic and inorganic fertilizers under vineyards (Garashany variety grapevines) under conditions of irrigated gray-brown soils. Calculation of the constants of the solubility product of the solubility factor of soil phosphates using various forms and doses of organic and inorganic fertilizers under conditions of carbonate gray-brown soil based on the analyzes carried out. It has been established that the use of organic and inorganic fertilizers separately and together in various doses and ratios contributes to the regulation of the phosphorus regime of the gray-brown soil of Absheron, which has a positive effect on soil fertility and grape yield.
