Crop cultivars now being grown in no-till production systems were developed by selecting for performance in conventionally tilled environments. In order to maximize production of corn (Zea mays L.), cotton (Gossypium barbadense L.), and soybean [Glycine max (L.) Merr.] in a no-till environment, it may be necessary to select for performance under the same conditions. The economic incentive for d...

Tillage has been and will always be integral to crop production. Tillage can result in the degradation of soil, water, and air quality. Of all farm management practices, tillage may have the greatest impact on the environment. A wide variety of tillage equipment, practices and systems are available to farmers, providing opportunities to enhance environmental performance. These opportunities hav...

Literature reporting the development of conservation tillage and the research that has been conducted on nematode control in crops grown in conservation tillage systems is reviewed. Effects of different types of conservation tillage on population densities of various nematode species in monocropping and multicropping systems, effects of tillage on nematode distribution in the soil profile, effe...

The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

In 1987, the United States Department of Agriculture (USDA-ARS) National Sedimentation Laboratory, in cooper­ ation with the Mississippi Agricultural and Forestry Experi­ ment Station (MAFES) and the Natural Resources Conservation Service (NRCS), initiated an interdisciplinary research project to develop profitable and environmentally sustainable conservation production systems for silty upland...

Tillage has long been an essential component of traditional agricultural systems. Broadly defined, tillage is the mechanical manipulation of the soil and plant residues to prepare a seedbed for crop planting. The benefits of tillage are many: it loosens soil, enhances the release of nutrients from the soil for crop growth, kills weeds, and regulates the circulation of water and air within the s...

Nowadays, using the technology and computers for decision making in a particular field is one of the subjects which in the level of making decisions and industrial managements has been very much noticed. Especially, the decision which on the base of current specific condition is required, such as making decisions in the selection of suitable primary tillage equipment for given conditions of a f...

Appropriate tillage plays an important role in mitigating the emissions of greenhouse gases (GHG) in regions with higher crop yields, but the emission situations of some reduced tillage systems such as subsoiling, harrow tillage and rotary tillage are not comprehensively studied. The objective of this study was to evaluate the emission characteristics of GHG (CH4 and N2O) under four reduced til...

Introduction Conservation tillage has been one of the most rapidly adopted agricultural practices of the past 15 years (CTIC, 1983). The primary impetus for conservation tillage has been decreased soil erosion; fuel, labor, and machinery costs; and increased soil water storage and yields (USDA, 1975). Conservation tillage may be broad­ ly defined as tillage practices that reduce soil and water ...

Kucey and Schaalje, 1986; Reeves et al., 1993; Randall et al., 1997; Torbert et al., 2001). Tillage and N management systems can have a significant effect Many soil and water quality problems are associated on N use by corn (Zea mays L.) and nitrate (NO3–N) movement with conventional tillage, along with other problems that through the soil profile. Potential water quality and NO3–N loss probaff...
