Summary

The problems of the nutrient balance study under vineyards in the light-chestnut soils of Ganja-Gazakh of Azerbaijan are examined. 3,84kg/h of N/NH3; 0,99kg/h of N/nO3 P₂O₅ of 1,16kg/h penetrate into the soil with the atmosphere precipitations, but 1,73; 1,55; 1,05; 21,69kg/h with the irrigative waters. A total annual nitrogen-6,87-7,29%, phosphorus-0,59-0,79%, potassium-3,92-7,29% were leached from the scattered fertilizer into lizimeters. While a weight of the dry mass and a total quantity of the nutrient increase, an outlet with the annual trimming materials and crops has raised. It is established that a balance of nitrogen, phosphorous and potassium under all the versions of the experiment is positive. The balance under a control version where deficit of the nutrient is negative. At an application of fertilizer under the version of N₉₀P₁₂₀K₁₂₀ the balance forms for nitrogen +41, 8-(+44,6); phosphorus +102,2-(+110,1), potassium +81,1-(+85,6) kg/h.
