Research on soil nutrient released from rice straw buried in deep soil layer by rotocultivator and the effect of yield promotion in paddy fields
The nutrient of C, N, P, K in rice straw buried by rotocultivator in deep soil layer released at a high rate and less remain than on surface soil. Buried rice straw in deep soil layer can improve the C, N, P, K of soil nutrient and effect of yield promotion is notable.
