Comparison of soil microbial community catabolic diversity between rhizosphere and bulk soil induced by tillage or residue retention

The effects of long term no-till and crop residue on soil microbial community catabolic function and relevant carbon cycle in the rhizosphere and bulk soils were assessed in the 10th year of a maize-winter wheat-soybean crop rotation. Conventional and zero tillage were coupled with residue removal a...
