Bacterial communities are important not only in the cycling of organic compounds but also in maintaining ecosystems. Specific bacterial groups can be affected as a result of changes in environmental conditions caused by human activities, such as agricultural practices. The aim of this study was to analyze the effects of different forms of tillage and residue management on soil bacterial communi...

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 and residue retention in a factorial design. Soil microbial community catabolic diversity was dete...

wheat residues management and modification in tillage time are among suggested practices in weed control. to evaluate the effects of wheat residues and tillage time on weed dry matter and leaf area, corn dry matter and corn grain yield, a study was conducted at darab agriculture and natural resource college, shiraz university during growing season of 2008-2009. this experiment was conducted in ...

Soil organic carbon (SOC) and nitrogen (N) are directly influenced by tillage, residue return and N fertilization management practices. Soil samples for SOC and N analyses, obtained from a 23-year field experiment, provided an assessment of nearequilibrium SOC and N conditions. Crops included corn (Zea mays L.) and soybean [Glycine max L. (Merrill)]. Treatments of conventional and conservation ...

soil organic carbon is a key factor in productivity and quality of soil and environment particularly in semi arid regions. in this article, the role of farm soil organic matter management in soil and in land is discussed. the variability of soil organic carbon in drylands is mainly controlled by tillage and crop residue management. results of this study indicated that usage of correct tillage m...
