METHOD OF SOIL PREPARATION TO RICE SOWING IN FALLOW OF RICE CROP ROTATION Russian patent published in 2012 - IPC A01B79/02 A01G16/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and land reclamation. The method includes an autumn tillage by disking, harrowing, sowing of winter crops and wintering intercrops, their harvesting and planting rice.
