    Rotation and manure amendment increase soil macro-aggregates and associated carbon and nitrogen stocks in flue-cured tobacco production

    ZOU Congming; LI Yan; HUANG Wei; HU Xiaodong; ZHAO Gaokun; YANG Xuebiao; CAI Yonghao; JIN Yan
    Yunnan Academy of Tobacco Agricultural Sciences of CNTC, Kunming City, Yunnan Province, P.R. China
    Flue-cured tobacco production in China is typically over-fertilized and mono-cropped. To understand how this agronomic management affects soil structure and organic matter, this study investigated the effect of rotation, fertilizer rate and manure ...
