“…Unsustainable agricultural practices have resulted in extreme soil erosion (Cai et al, 2006;Jiang et al, 2007), which can lead to physical and chemical degradation (Lal et al, 2000). In response to the decline in regional soil quality in the Loess plateau, there has been a gradual shift from conventional tillage towards conservation tillage practices such as zero tillage farming, crop residue retention and crop rotation.…”

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 10 th 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 determined using Biolog-Eco plate. Average well colour development value (AWCD) of the microbial community in the rhizosphere soil was significantly higher than that in the bulk soil. Soil organic carbon (SOC) and microbial biomass carbon (MB-C) content of rhizosphere soil under both zero tillage and residue removal treatments were significantly higher than those in the bulk soil. Microbes in bulk soil presented a preferential utilization of diverse carbon sources when crop residue was retained. Zero tillage significantly increased the utilization of most carbon sources of microbial in the rhizosphere compared to conventional tillage. Principal component analysis (PCA) of the distribution of carbon substrate utilization for all treatments suggests that the microbial community catabolic diversity is different between the tillage management treatments and between soil sampling positions. Effects of zero tillage and crop residue retention were different with respect to the microbial catabolic diversity in the rhizosphere and the bulk soil.

“…With topsoil loss, subtle changes occur in soil properties, which reduce crop productivity and create soil management problems (Christensen and McElyea, 1988;Larney et al, 2000Larney et al, , 2003Fabrizzi et al, 2003). Thus, prevention of soil erosion and enhancement of soil quality are cornerstones of sustainable agriculture (Lal et al, 2000).…”

Abstract. Organic carbon is one of the common indicators used in studies on global climate change for major problems of land degradation, desertification and biodiversity decrease. Carbon as one of the absolute necessary element is indispensable for survival of all living beings. Soils are carbon sources for the land as well as the atmosphere. For that reason, surface carbon amounts and certain parameters were analyzed in this study for the soils in which medicinal and aromatic plants are grown. In this study, physical and chemical analyses were carried out in disturbed soil samples which were taken out at two different depths from totally 60 points in areas with three different medicinal and aromatic plants (Rosmarinus officinalis, Salvia officinalis, Origanum onites) found in Adiyaman-Kahta district. The soils in the study area were determined to have no drainage problem, with clay and clay-loam texture (37.27%), low alkali pH (7.67), to be saline-alkaline (EC: 0.31 dS m -1 ), to have very low calcareous content (1.11%) and medium-level organic matter (2.13%). In terms of nutritional elements, it was determined that there were very low nitrogen (N) (0.07%), some phosphorus (P) (4.28 kg da -1 ) and zinc (Zn) (0.54 ppm), high potassium (K) (157.39 kg da -1 ) and iron (Fe) (5.31 ppm), and adequate amount of copper (Cu) (2.13 ppm) and manganese (Mn) (5.98 ppm). Organic carbon concentration of the soils was between 2.42 and 5.05 kg m -2 , and determined to be 3.76 kg C m -2 as mean. Inorganic carbon concentrations varied between 2.75 and 5.36 kg m -2 , and determined to be 4.08 kg m -2 on mean. In this case, the highest organic and inorganic carbon concentrations in the study area were found to be in areas where sage (Salvia officinalis) plant grew.
