Use of herbicides, tillage, and grazing cattle for establishment of corn in rotation with alfalfa and rye
… of glyphosate, 6) alfalfa grazing plus autumn disking (no herbicides). Grazing until corn planting decreased (P<0.05) alfalfa stands and rye biomass, but increased (P<0.05) corn plant populations and soil bulk density compared to shorter grazing periods. Grazing prior to rye jointing increased …

Long term effects of wet site timber harvesting and site preparation on soil properties and loblolly pine (Pinus taeda L.) productivity in the lower Atlantic Coastal Plain
… preparation as the whole plot factor (bedding, disking with bedding, disking, and no site preparation), and two levels of traffic as the subplot factor (primary skid trail, no obvious traffic). After 23 years, bedding and disking with bedding treatments effectively enhanced soil physical …

Mitigation of harvesting disturbances on a forested wetland in the South Carolina lower coastal plain
… Site preparation treatments such as bedding, disking, and fertilization are often employed on harvested sites to mitigate these impacts; however, their effectiveness has not been fully documented. Moreover, a distinction between rutting and compaction has not been made in previous research. …

EVALUATING MINE SOIL PREPARED BY SCRAPER PANS FOR HERBACEOUS PLANTS AND PINE SEEDLINGS AT AN EAST TEXAS LIGNITE SURFACE MINE
… block design: 1) No Tillage (control); 2) Disking (30-35 cm depth); 3) Single-Ripping (90 cm depth)/Disking (30-35 cm depth); and, 4) Cross-Ripping (90 cm depth)/Disking (30-35 cm depth). Soil physical and chemical properties were investigated at 0-30, 30-60, and 60-90 cm depth intervals. …

Vegetation response of a Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) community to 6 mechanical treatments in Rich County, Utah
… fall of 2001 and spring of 2002 (aerator only). Disking and imprinting killed 98% of the sagebrush and significantly (p < 0.05) lowered cover and density of sagebrush more than any other treatment. Disking and imprinting was the only mechanical treatment to reduce cover and density of residual …

Response of avian, arthropod, and vegetation communities to mid-contract management in Conservation Reserve Program tall fescue monocultures
… effects of 3 MCM regimes, including fall strip disking, fall herbicide spraying (hereafter, spray), and fall herbicide spraying in combination with spring legume interseeding (hereafter, spray-seed) on nearly 650 ha of tall fescue (Schedonorus phoenix [Scop]. Holub; nomenclature follows USDA …

Biophysical economic analysis of nutrient and sediment management practices in the Mississippi Alluvial Valley
… to heavy rainfalls) in this watershed required disking every four to five years to help maintain yields. Simulated results showed that nitrogen fertilizer management, and conservation tillage, were cost-effective in helping reduce nutrient effluent runoff. Changes in tillage management helped …

Energetics of low-input corn production
… treatment. Cover-cropped treatments that used disking to kill the cover crops required an average energy expenditure of 9781 MJ/ha compared to 18,488 MJ /ha required by the standard-practice winter-fallow treatment. Alternative-practice treatments that utilized vetches to provide nitrogen for …

Effects of Soybean Cultivars and Planting Dates on Biomass Production
… at the rate of 175 kg ha-1 and covered by disking. Average biomass production (oven dry basis) decreased progressively (2918, 2450, and 2088 kg ha-1) for the later planting dates. For the June 2 and June 16 planting dates, biomass yields increased for successive harvest dates; however, for …

Impact of carbofuran on spring-seeded alfalfa and associated insect pests
… with conventionally planted fields prepared by disking a small grain cover crop, and were effectively controlled by carbofuran. Conventional plantings without a previous cover crop and no-till plantings were not visibly affected by seedcorn maggots. Potato leafhopper populations were not …

Stress Estimation From Borehole Scans For Prediction Of Excavation Overbreak In Brittle Rock
… validated by the geometry of stress-induced core disking. From the lab material properties and breakout geometries, a continuum based, back analysis of breakout was done through the creation of a generic database of stress dependent numerical models. When compared with the in situ breakout …

'It Should've Never Been Broke Out': Understanding Participation in the Conservation Reserve Program in Southwest Kansas and Southeast Colorado
… grass species and management practices such as disking, interseeding, and grazing. A dominant theme emerged from producers, echoed by field staff, in the benefits of grazing and need for CRP to increase flexibility to maximize grazing compatibility. Broader program concerns included a shifting …
