The effects of cereal crop residues on paddy soils


, : The effects of cereal crop residues on paddy soils. Extension Bulletin, ASPAC Food and Fertilizer Technology Center (49): 29

In Japan, rice straw has customarily been returned to the soil in the form of compost, but this practice has been progressively decreasing due to the increasing use of chemical fertilizers, the change from draft animals to machinery and the labour shortage.
