METHOD FOR RECLAMATIVE PREPARATION OF DRAINED MINERAL SOIL FOR SOWING OF GALEGA ORIENTALIS Russian patent published in 2013 - IPC A01B79/02 A01G1/00 A01C1/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and land reclamation. The method includes selection of a ventilated area with no shade, with fertile drained reclaimed soil of sandy-loam or light-loamy grain size and acidity close to neutral. Main treatment of soil in the year before sowing includes clipping of stubble, application of organic and higher doses of mineral phosphorus and potassium fertilisers for plowing with a colter for depth of ploughed layer and pre-sowing treatment of soil. After plowing of soil, if level of ground water is not more than 10 cm above the bottom of drains, deep tillage is carried out for depth of at least by 25 cm of less than depth of drains installation at the angle of 45° to their direction with minimum permissible distance between strips with simultaneous combing of stones and their further removal. At least in a month, if ground water level is not more than 10 cm above the bottom of drains, deep tillage is repeatedly carried out in direction perpendicular to the direction of the first tillage with the same distance between strips with simultaneous combing out of stones and their subsequent removal. Moreover, the depth of repeated deep tillage is by 10-15 cm less than of the first one. In process of tillage a layer of peat is added onto a plough foot with thickness of at least 15 cm, and organic fertilisers are represented by multi-purpose compost in the dose of 10-15 t/ha.

EFFECT: method makes it possible to reduce amount of weeds and extent of soil compaction, to improve their water-air regime and development conditions, and also to accelerate growth of underground part of plants.
