METHOD FOR PRE-PLANTING APPLICATION OF MOLYBDENUM FERTILIZERS INTO THE SOIL FOR RICE IN KUBAN CONDITIONS Russian patent published in 2023 - IPC A01C21/00 A01G22/22 

FIELD: agriculture.

SUBSTANCE: invention is related to technology of rice cultivation. The method of pre-sowing introduction of molybdenum fertilizer into alluvial meadow soil for rice seeds in Kuban conditions includes a preliminary analysis of alluvial meadow soil for the content of mobile molybdenum in it. The soil is ranked into three groups: the first group includes soil with a low content of mobile molybdenum in an amount of less than 0.20 mg/kg, the second - soil with an average content of 0.2-0.25 mg/kg, the third - soil with high content of mobile molybdenum in an amount greater than 0.25 mg/kg. In soil with low content of mobile molybdenum, molybdenum fertilizers are applied before sowing rice at the rate of 2 kg/ha for the active substance, and in soil with an average content of molybdenum, the rate of applied molybdenum fertilizers is reduced by half. At the same time, the introduction of molybdenum fertilizer is carried out for five years before sowing rice, in high rice bays, in form of an aqueous solution, burying it with disc harrows, with a short flooding irrigation of the rice field.

EFFECT: increase of yield of rice and reduction of consumption of molybdenum fertilizers.
