Preconditional factors affecting the adoption of conservation tillage practices for Elgin, Middlesex and Oxford counties (Ontario).
… influence farmers' adoption of conservation tillage for three southwestern Ontario counties: Elgin, Middlesex and Oxford. Nine independent variables were designed and tested against the adoption of conservation tillage. The independent variables represented physical conditions on each farm as …

Surface and groundwater quality impacts of conservation tillage practices on burley tobacco production systems in Southwest Virginia
… and deep percolation losses from conventional tillage (CT), strip tillage (ST), and no-till (NT) treatments in a burley tobacco production system. The field experiment results show that the CT treatment yielded more total runoff, 93.6 mm, than ST and NT. Compared to the CT treatment, ST reduced …

Broad-scale Assessment of Crop Residue Management Using Multi-temporal Remote Sensing Imagery
Tillage practices have changed dramatically during the past several decades as agricultural specialists have recognized the unfavorable environmental effects of mechanized tillage. Alternatively, conservation tillage management can mitigate adverse environmental impacts of tillage, such as soil and …

Seasonal variations in preferential flow under corn and soybean cropping
… flow under different cropping systems and tillage practices during the growing season is lacking, which has complicated the making of sound and reasonable regulatory decisions on the use of agrichemicals. In order to investigate the effect of tillage, cropping and row position on chemical …

Effects of Farm Management Practices on Pest Slugs and Slug Predators in Field Crops
… methods that include reducing or eliminating tillage and planting high residue cover crops. These practices are associated with an increase in moderate to severe damage to field crops by slugs. Conserving, and even enhancing, natural enemy populations is a desirable way to manage slug …

Effects of tillage and mulching on selected soil properties, growth and yield of sunflower (Helianthus annuus L.)
Excessive and unnecessary tillage without residue retention can degrade the soil’s physical quality, decrease soil organic carbon contents and crop yields. Although the benefits of improved tillage methods and mulching have been reported in literature, little information is available on South …

Effects of Biosolids on Carbon Sequestration and Nitrogen Cycling
… and 3) to compare biosolids types and tillage practices on short-term N availability in the Coastal Plain soils. Biosolids led to C accumulation in the soil surface (< 15 cm) after long-time application in both Piedmont and Coastal Plain soils. The C saturation phenomenon occurred in …

Management and assessment of winter cover crop systems for supplying nitrogen to corn in the mid-Atlantic region of the United States
… desiccated cover crop residue using no-tillage practices. Two field studies including rye (Secale cereale L.), hairy vetch (Vicia villosa Roth), and rye+hairy vetch cover crops were established to determine the influence of cover crop management on N availability to corn (Zea mays L.). …

Enhanced efficiency phosphorus application for corn
… research are (1) to determine the effects of tillage/fertilizer placement [no-till (NT)/surface broadcast or strip-till (ST)/deep banding], monoammonium phosphate rate [0, half the recommended rate, and the recommended rate], and the presence and absence of two enhanced phosphorus efficiency …

Simulating the Impacts of Land-Use Land-Cover Changes on Cropland Carbon Fluxes in the Midwest of the United States
… as changes in cropland production technologies, tillage practices, and planted crop species, could have large impacts on carbon fluxes. However, the impacts remain highly uncertain at regional to global scales. Satellite remote sensing is commonly used to create products with geospatial …

Stenocarpella Maydis: Identification, Management, and Population Diversity
… ii) evaluate the effect of crop rotation and tillage on DER severity, iii) determine the survival period of S. maydis in corn residue at different soil depths in a corn field, and iv) identify genetic diversity among S. maydis isolates collected from the Midwestern and Southern United States. …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
… that can impact water quality. Conventional tillage practices in the U.S. has reduced or stopped, making subsurface injection of manure a promising option when compared to surface application. Our research compared manure application methods, manure application seasons, cropping system, and …

Influence of Transplanter Modification and Previous Crop on the Production of No-Till Dark Tobacco
… been produced using<br />conventional tillage practices. Soil is cultivated multiple times throughout a growing season leading to an increased incidence of soil erosion. No-till systems have been growing in popularity with the advent of new technology that has enabled the practice to be …

Nematodes as indicators of sustainable soil health management practices in corn-soybean production
… communities under different crop management practices. The first study evaluated the use of soil DNA for profiling nematode communities. Compared to the commonly used NF1/18Sr2b primer, degenerate primers (NemF/18Sr2b and NemFopt/18Sr2bRopt) combined with an improved soil DNA extraction …

Long-term effect of crop rotation and tillage on soil properties
… forages to mostly annual crops has intensified tillage, and led to the development of conservation tillage practices such as no-till. There is a shortage of information about the interactive effects of rotation and tillage on soil productivity, and consequently, the long-term effect of these …

Inheritance of reactions to gray leaf spot and maize dwarf mosaic virus in maize and their associations with physiological traits
… factor in maize where continuous minimum tillage practices are followed. Commercial corn hybrids were evaluated for response to gray leaf spot for seven years at two Virginia locations (Shenandoah and Wythe Counties) and one year at a third location in Virginia (Montgomery County). Yield …

Turning a problem into a solution: heterogeneities in soil hydrology
… Additionally, it was shown that dif-ferent soil tillage practices did not affect the soil moisture dynamics at all. The presented approach does not require a priori assumptions about the nature of physical processes, and it is not restricted to specific scales. Thus, it opens various …
