METHOD OF INCREASING DEGRADED PASTURES PRODUCTIVITY Russian patent published in 2008 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method involves primary and surface tillage, weeds elimination and fallow farming, secondary tillage, autumn sowing of cereal grass seeds and prevernal sowing of legume and cereal grass seeds. Tillage for fallows is carried out with strip farming on the overgrased pastures. Loam soils are tilled by subsurface cultivators at the depth of 20...22 cm in the first and second ten-day periods of September. In the prevernal period tandem disc harrowing is carried out as well as slits forming with a pitch of 0.7-1.1 m at the depth of 0.35-0.45 m and cultivation with harrowing at the depth of 8...10 cm. During summer cultivation by knife operation elements at the depth of 4...5 cm takes place together with simultaneous packing of soil by star-wheeled rollers. In autumn cereals grass seeds are sown at the depth of 2...3 cm with row spacing equal to 30 cm and seeding rate equal to 10...12 kg/ha, in the prevernal period mineral fertilisers, mainly ammophoska are introduced to the thawed-frozen soil with the rate of 0.2 t/ha. Legume and cereal grasses are sown after surface harrowing and presowing tillage at the depth of 4...5 cm for legume grasses and 2...3 cm for cereal grasses.

EFFECT: method allows improving degraded lands and reducing costs.
