Mechanisms of Soil Aggregates Stability in Purple Paddy Soil under Conservation Tillage of Sichuan Basin, China
Abstract: Ridge culture is a special conservation tillage method, but the long-term influence of this tillage system on soil aggregate-size stability in paddy fields is largely unknown in southwest of china. The objectives of this paper are to evaluate soil aggregates stability and to determine the relationship between SOC and soil aggregate stability.Soil samples at 0-20 cm layer were adopted ...
متن کاملFungal Communities in Rhizosphere Soil under Conservation Tillage Shift in Response to Plant Growth
Conservation tillage is an extensively used agricultural practice in northern China that alters soil texture and nutrient conditions, causing changes in the soil microbial community. However, how conservation tillage affects rhizosphere and bulk soil fungal communities during plant growth remains unclear. The present study investigated the effect of long-term (6 years) conservation (chisel plow...
متن کاملImproving 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 کاملDIVISION S-6—SOIL & WATER MANAGEMENT & CONSERVATION Conservation Tillage Systems for Cotton in the Tennessee Valley
ern Tennessee (Stevens et al., 1992; Bradley, 1993; Triplett et al., 1996), conservation tillage practiced on silty clay Yield reductions from no-tillage cotton (Gossypium hirsutum L.) soils in northern Alabama resulted in 8 to 15% yield jeopardized adoption of conservation systems in the Tennessee Valley region of north Alabama in the early 1990s. We conducted a study from reductions compared ...
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 ...
