METHOD FOR FERTILIZATION OF PERENNIAL GRASSES ON CALCAREOUS SOILS Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: method involves one-time placement of mineral fertilizers at the rate of three yearly norms containing 350 kg/ha of phosphorus and 200 kg/ha of potassium, using nitrogenous fertilizers twice only in the first year at the rate of 200 kg/ha. In comparison with the currently-used method the cropping power is increased by 59.0 and 76.0 metric centners/ha with respect to alfalfa hay and siloed maize, respectively. EFFECT: higher position accessibility of fertilizer, reduced wash-off of fertilizers from the field surface and higher cropping power of fodder cultures.
