Against such a background, a short-term (60 days)greenhouse simulation experiment was carried out to study the effectsof straw placement, external mineral N source and tillage on strawdecomposition of maize and cotton in two contrasting soils, a redsoil (Ferrasol) and a black soil (Acrisol).展开更多

文摘With the present understanding that decomposing straw may not onlyaffect soil properties, but pos- sibly greenhouse gas emissions aswell, focus among environmental researchers has gradually expanded toinclude understanding of decomposition rate and stability of straw ofdifferent plants in different soils under different managementconditions. Against such a background, a short-term (60 days)greenhouse simulation experiment was carried out to study the effectsof straw placement, external mineral N source and tillage on strawdecomposition of maize and cotton in two contrasting soils, a redsoil (Ferrasol) and a black soil (Acrisol).
