Soil Aggregate Stability and Aggregate-Associated Carbon Fractions under Different Tillage Systems of Rice-Wheat Rotation in North India

effect of aggregate stability indices on wheat yield in a soil with high specific surface under different tillage methods

effects of different tillage systems on dispersion ratio, status of aggregation, degree of aggregation, mean weight diameter, geometric diameter, the rain-fed wheat yield and the yield components were investigated by a field trial using a completely randomized block design with five treatments in four replicates during 2009-2010 growing season at gorgan university of agricultural science and na...

Effects of Different Tillage and Straw Return on Soil Organic Carbon in a Rice-Wheat Rotation System

Soil management practices, such as tillage method or straw return, could alter soil organic carbon (C) contents. However, the effects of tillage method or straw return on soil organic C (SOC) have showed inconsistent results in different soil/climate/cropping systems. The Yangtze River Delta of China is the main production region of rice and wheat, and rice-wheat rotation is the most important ...

Soil aggregate stability as affected by fertilization type under 1 semiarid no - tillage conditions

Statistical and Geostatistical Appraisal of Spatial Variability of Aggregate Stability and Aggregate-Associated Organic Carbon Content on a Catchment Scale in a Semi-arid Region, Central Iran

In a semiarid region of central Iran, effects of parent materials, physiography and landscape position, land use, andmanagement practices on association of organic carbon with secondary (aggregates) particles and aggregate stability canhave important consequences in terms of carbon sequestration and budgeting, deciding on the proper land use strategy andsuitable soil conservation practices. It ...

Determination of Soil Aggregate Stability in Different Types and Amounts of Organic Matter in Khuzestan Plain, Iran

In soils under wheat cultivation, soil aggregates stability is increased and destructive effects of erosion decreased, due to organic matters (OM) application. This trail was conducted in Shavoor agriculture research station to determine of mean weight diameter (MWD) under different organic matter sources and amounts in Khuzestan province (at south west of Iran) via a split plot experiment base...
