METHOD FOR CULTIVATION OF SOYA UNDER IRRIGATION CONDITIONS Russian patent published in 2007 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method involves tilling soil including mulching cutting of upper soil layer to 10-12 cm depth; forming loosened vertical slots; sowing seeds and simultaneously forming intermittent furrows; providing loosened vertical slots to 33-35 cm depth in direction of prevailing winds; sowing seeds and forming intermittent furrows in direction perpendicular to direction of slot. Furrow is formed as trapezium with parallel lower and upper sides having length of 5-6 cm and 10-12 cm, respectively; depth of furrow is 8-10 cm. Loosened vertical slots are spaced from one another by distance of 140 cm. Seed row spacing is set in accordance with requirements for particular crop. Furrow is 80-120 cm long; its intermittence portions are 15-25 cm long.

EFFECT: increased efficiency due to maximum accumulation of moisture in vitally important zone of plant, reduced moisture evaporation losses, increased efficiency in utilization of fertilizers, reduced presence of contaminants in soya seedling rows, and increased crop yield.
