METHOD OF SOIL IMPROVEMENT IN FALLOW OF RICE CROP ROTATION FOR RICE SOWING Russian patent published in 2013 - IPC A01G16/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and land reclamation. The method includes watering, disking of the soil after mass weed emergence, harrowing and moisturising watering followed by surface treatments. First a provocative wetting the soil with water is carried out to complete moisture saturation of its root zone with a depth of 0.06-0.08 m. Then, after the mass emergence of the weeds, disking of the soil is carried out to a depth of 0.1-0.12 m with simultaneous harrowing to complete destruction of the grown vegetation. After new weed sprouting emergence and red grained forms of rice a layer of water is created, covering completely the vegetative plants, which is supported for one or two weeks till the complete destruction of weeds and red grained forms of rice, and then it is left it without treatment until spring. Before sowing rice in spring surface tillage is carried out to a depth of seeding down with simultaneous destruction of the remnants of weed vegetation.

EFFECT: method enables to obtain rice fields clean from weeds, to increase the degree of equalisation of checks plane, to eliminate chemical treatments of rice crops against weeds, to improve reclamation-ecological condition in the rice system, and to increase yields.
