FIELD: agriculture.
SUBSTANCE: method involves introduction of dolomite flour with due allowance for its hydrolytic acidity with subsequent embedding into soil. Gypsum-containing product and dolomite-containing product are added in the form of fertilizer based on gypsum and dolomite flour, obtained by stirring in an open area, at ratio of 1:1 by weight in amount of 4 t/ha in spring on soil surface with subsequent ploughing to depth of 20-22 cm. Early ripe hybrid of maize "Amavit" with FAO values within range of 100-200 is used. Maize seeds are sown at the beginning of the first decade of May with a seeding rate of 20 kg/ha.
EFFECT: method provides higher yield of corn hybrid in conditions of leached chernozem of the Middle Volga region.
