A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...

Interest in tillage impacts on sequestration of soil organic carbon (SOC) has increased greatly during recent years. The use of reduced and no-tillage (NT) practices generally increases the SOC concentration in surface few centimeters when compared to conventionally tilled soils. However, use of conservation tillage does not always result in increased SOC storage overall. The effects of sample ...
the objective of this work was to study the effects of tillage and liquid manure applications on some physical and chemical properties as well as on the carbon and nitrogen mineralization potential of a meadow soil. our results indicated that tillage and manure applications had no effect on the concentration of cu, mn, total n and organic c in 0-15 cm layer of soil after 15 years of treatment. ...
lack of sufficient information on conservation tillage systems leads to the dominating use of conventional tillage practice in most parts of iran. testing other management practices may help in decision making regarding the types of tillage systems that reduce soil deterioration. a three- years field experiment was conducted to study the effects of conventional (ct), reduced (rt) and no-till (n...
The effects of water erosion (including long-term historical erosion and single erosion event) on soil properties and productivity in different farming systems were investigated. A typical sloping cropland with homogeneous soil properties was designed in 2009 and then protected from other external disturbances except natural water erosion. In 2012, this cropland was divided in three equally siz...
Conservation practices are implemented on farm fields in the USA through Farm Bill programs; however, there is a need for greater verification that these practices provide environmental benefits (e.g., water quality). This study was conducted to assess the impact of Farm Bill eligible conservation practices on soluble P (SP) and total P (TP) losses from four fields that were monitored between 2...
Hairy vetch (Vicia sativa L.) succeeded by corn (Zea mays L.)or grain sorghum (Sorghumbicolor L. Moench) were seeded insplit plots randomized within whole plots of no-tillage versus conventional tillage over four growing seasons (1980-83). The vetch-corn cropping system increased the density of Meloidogyne incognita 2.9 X more than the vetch-grain sorghum cropping system. I n contrast, the vetc...
Conservation tillage and even no tillage as a practice is not new. However, there appears to exist evidence that in some cases no-tillage is successfully incorporated into a new concept of truly sustainable agriculture, gaining popularity as “conservation agriculture” all over the world. Conservation Agriculture is, besides no-tillage and direct planting, based on very old concepts such as gree...
