Mid-crops accelerate rice field soil cultivation and increase rice yields. When spring rape is introduced into the rice crop rotation, the soil acquires an increased ability to restore the soil layer. The bulk density of soil in the rice–spring rape crop rotation decreases by 8 … 10%. When cultivating rice on a reclamation field, this indicator increases by 4 … 6%. It has been established that rapeseed crops have phytomeliorative properties, improve the ameliorative state of rice fields, have a positive effect on the fertility of brown semi-desert soil, and increase rice productivity.
