Data from Loamy sand soil approaches organic carbon saturation after 37 years of conservation tillage This is digital research data corresponding to a published manuscript, Loamy sand soil approaches organic carbon saturation after 37 years of conservation tillage.
Conservation tillage is reported to increase soil organic carbon (SOC) and total nitrogen (TN) contents, but; long-term (> 30 years) fi...
Mepiquat chloride applications across two nitrogen rates in a conservation tillage cotton system In cotton production, a plant growth regulator is a management tool to limit excessive cotton (Gossypium hirsutum L.) vegetative growth, but over-application can promote early cut-out and sometimes decrease yield. Specific information on how different plant growth regulator application strategies p...
Conservation tillage and soil water In the semiarid U.S. Great Plains, reduced or no conservation tillage has been primarily directed towards the control of soil erosion either by wind or water in contrast to conventional tillage practices that bury some fraction or all of the crop residue. The type, depth and degree of soil disturban...
Single species and mixtures for corn production in Alabama Benefits associated with conservation tillage and single species cover crops have been documented across the Southeast, but there is tremendous interest in how cover crop mixtures compare with single species. We examined how two cover crop mixtures of rye (Secale cereale L.) and crimson clover (Trif...
Grazing winter rye cover crop in a cotton no-till system: Soil strength and runoff Grazing cool season cover crops (CC) could provide an economic incentive to increase cover crop adoption in the Southeast USA if negative impacts on soils can be avoided. Using four small catchments with a long history of cover crops and conservation tillage located in the southern Piedmont of Geor...
Estimates of conservation tillage practices using Landsat archive The USDA Environmental Quality Incentives Program (EQIP) provides financial assistance to encourage producers to adopt conservation practices. Historically, one of the most common practices is conservation tillage, primarily the use of no-till planting. The objectives of this research were to determ...
Furrow-irrigation application efficiency in mid-southern USA conservation tillage systems Approximately 80% of mid-southern USA irrigation requirements are supplied through gravity flow delivery systems with inherently low application efficiency. This research was conducted to determine whether the efficiency of furrow-irrigation systems could be manipulated through conservation tillage...
Model prediction capacity of ephemeral gully evolution in conservation tillage systems Ephemeral gully (EG) erosion has an important impact on agricultural soil losses and increases field surface hydrology connectivity, transporting pollutants to nearby water bodies. Watershed models including an EG component are scarce and not yet properly evaluated. The objective of the study was to...
Cover Crop Management Cover crops have long been recognized as an important component of conservation tillage systems due to the many benefits they provide. Finding the right plant or mix of plants that both fits into a “window” or “niche” within the crop
rotation and accomplishes your objectives is a key component of c...
Soil fertility in conservation tillage systems Soil forming factors (climate, biology, parent material, and drainage) and nutrient management practices heavily influence soil fertility. This article highlights the impacts of soil properties and tillage intensity on nutrient availability in agricultural soils. While organic matter and nutrients t...
