Description The objectives of this study were to exalnine the ill1pact of 11 years of sequential cropping under
ilnproved and traditional managenlent on crop yield, soil organic carbon (SOC) and Inicrobial biOlnass C
(MBC) in Vertic Inceptisols under senu arid condition. hnproved management comprised of sowing on
broadbed-and-furrow landfonn and additions of nutrhnents through cOInposted crop residues and pnming of
Glyricidia sepimn(L) -used as an hedge between plots of tIns modality, while traditional managelnent
consisted of sowing on grade land form and no addition of organic som'ces of nutriment. The higher SOC
content was found in ll1edium depth soil under iInproved management, which ranged between 1.07% and
1.2% with a lnean of 1.130/0, the lower SOC content is recorded in medium depth traditional mauagelnent,
which ranged between 0.51 % and 0.94% with a mean value of 0.66%. The SOC content increased between
2002 and 2006 with higher value for iInproved management (+0.42%) cOlnpared to traditional managelnent
(+0.28%). The MBC content is not influenced by management system and soil depth.
