Preserving soil and crop resources by increasing cropping intensity and decreasing tillage

Soils perform many essential functions for plant growth, water storage, and water and air quality. Future generations depend on our crop and soil management practices to maintain or improve the soil’s ability to perform these essential functions while providing the food and fiber needed by society. Unfortunately, many soils have been degraded because we either did not understand the negative ef...

Remote sensing of crop residue cover and soil tillage intensity

Management of plant litter or crop residues in agricultural fields is an important consideration for reducing soil erosion and increasing soil organic C. Current methods of quantifying crop residue cover are inadequate for characterizing the spatial variability of residue cover within fields or across large regions. Our objectives were to evaluate several spectral indices for measuring crop res...

Dryland soil chemical properties and crop yields affected by long-term tillage and cropping sequence

Information on the effect of long-term management on soil nutrients and chemical properties is scanty. We examined the 30-year effect of tillage frequency and cropping sequence combination on dryland soil Olsen-P, K, Ca, Mg, Na, SO4-S, and Zn concentrations, pH, electrical conductivity (EC), and cation exchange capacity (CEC) at the 0-120 cm depth and annualized crop yield in the northern Great...

Integrative impacts of soil tillage on crop yield, N use efficiency and greenhouse gas emission in wheat-corn cropping system

Wheat-corn cropping system is one of the most important grain production systems in theworld. However, the integrative impacts of soil tillage on crop yield, N use efficiency (NUE)and greenhouse gases (GHGS) emissions are not well documented in this system. Thus, a twoyear field experiment was carried out in a typical wheat-corn cropping system with four tillageregimes during the wheat season, ...

Changes in Soil Physical Properties and Crop Productivity as Influenced by Different Tillage Depths and Cropping Patterns

A series of field experiments was conducted at BARI central farm to observe the changes in soil densities, moisture retentive properties, and crop productivity as influenced by different tillage depths and cropping patterns. The tillage depth showed significant effect on wheat yield. Grain yield of wheat significantly increased from 2.86 t/ha (minimum tillage depth) to 5.33 t/ha (tillage depth ...
