Improving soil surface properties: a driving force for conservation tillage under semi-arid conditions
The effect of long term conservation tillage (CT) application on soil organic carbon (SOC) concentration, and on stratification ratios (SR) of SOC, soluble organic carbon (SOCs), microbial biomass carbon (MBC) and protease activity (PA) has been studied. The SR was established dividing values of these variables at 0-5 cm depth by values at 10-25 cm depth. The results were compared with those ob...
متن کاملImpacts of different tillage practices on some soil microbiological properties and crop yield under semi-arid Mediterranean conditions
Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...

متن کاملLong-Term Crop Response to Conservation Tillage
In 1987, the United States Department of Agriculture (USDA-ARS) National Sedimentation Laboratory, in cooper ation with the Mississippi Agricultural and Forestry Experi ment Station (MAFES) and the Natural Resources Conservation Service (NRCS), initiated an interdisciplinary research project to develop profitable and environmentally sustainable conservation production systems for silty upland...
متن کاملPrincipal Component Analysis for Soil Conservation Tillage vs Conventional Tillage in Semi Arid Region of Punjab Province of Pakistan
Principal component analysis is a valid method used for data compression and information extraction in a given set of experiments. It is a well-known classical data analysis technique. There are a number of algorithms for solving the problems, some scaling better than others. Wheat ranks as the staple food of most of the nations as well as an agent of poverty reduction, food security and world ...
