Management of crop residues and soil organic matter is of primary importance in maintaining soil fertility and productivity and in minimizing agricultural impact on the environment. Our objective was to determine the effects of traf®c and tillage on short-term carbon dioxide (CO2) and water (H2O) ̄uxes from a representative soil in the southeastern Coastal Plain (USA). The study was conducted o...

A field experiment with six treatments was conducted to study the nitrogen reserves in summer maize topsoil on the north China plain. Results showed that topdressing significantly increased topsoil nitrogen reserves. Summer corn topsoil nitrogen reserves were affected by several management measures. Shallow tillage, wheat straw no-returning and deep intertillage at the corn seedling stage signi...

In the northern part of Kazakhstan, zero-tillage2 technology has the potential to increase wheat/grain productivity by 20 to 50 percent above current levels. However, phasing out conventional tillage can only be gradual, as full conversion to zero-tillage will require important investments and farm organizational changes. Actual current area under conservation agriculture (CA) appears to be inc...

Due to payoff uncertainties combined with risk aversion and/or real options, farmers may demand a premium in order to adopt conservation tillage practices, over and above the compensation for the expected profit losses (if any). We propose a method of directly estimating the financial incentives for adopting conservation tillage and distinguishing between the expected payoff and the premium of ...

the objective of this study was to determine the quicker response of subsoil or surface soil to minimum tillage (mt) and conventional tillage (ct) and biofertilizers (bacillus coagulans, b), phosphorus fertilization (p) and integrated p and b (pb) under the wheat (triticum aestivum l vr. sardari) growing season. the experimental design was split plot laid out in randomized complete block design...

In this study the influence of three different tillage systems in combination with eight varying weed treatments applied within the establishment year and its effect on the final above ground leafless biomass production (after the third growing season) of short rotation coppice poplar is presented. The three tillage systems included variants with ploughing and harrowing, variants with cultivati...

Tillage information is crucial for environmental modeling as it directly affects evapotranspiration, infiltration, runoff, carbon sequestration, and soil losses due to wind and water erosion from agricultural fields. However, collecting this information can be time consuming and costly. Remote sensing approaches are promising for rapid collection of tillage information on individual fields over...

the challenge for today's researchers and practitioners agriculture, increase productivity while maintaining or improving environmental quality (including water, soil and air) to be ¬ rapid population growth and increasing demand for food, researchers are continuing to study the management of high yielding varieties suitable for growing to escape environmental stresses in dry conditions an...

This research focused on rill formation, rill density, and associated flow velocity distribution in rills at the field level and with different tillage treatments in the inland Pacific Northwest. The study was conducted by applying flow at three different rates under winter conditions, which provides the greatest potential for rill formation. The following tillage treatments were tested: chisel...
