The Effects Of Grazing Cover Crops On Animal Performance And Soybean Production, J. Brett Rushing, Rocky Lemus, J. G. Maples, J. C. Lyles
IGC Proceedings (1997-2023)
Grazing cover crops has the potential to offset costs incurred with cover crop establishment, thus incentivizing management adoption. Information regarding cover crop species in combination with grazing and their subsequent effects on soybean production is limited. A field trial was conducted in Newton, MS from 2019 to 2021 to assess these effects. Cover crop treatments included oats (O), O + crimson clover (OC), and OC + radish (OCR) were applied in a randomized complete block design with three replications. Cover crops differed in nutritive analysis; O had significantly lower mean CP, but greater total daily nutrients (TDN). Weaned beef steers …

Integrated crop-livestock systems can potentially produce more product per unit of land with minimal impacts on soil health and cash crop quality. In the Upper Midwest there is an opportunity to graze fall cover crops (CC) after winter wheat in a corn-wheat rotation. In East Lansing, Michigan, two CC treatments: 1) a pure brassica mixture (PURE), and 2) a complex mixture containing legumes, warm and cool season grasses, and brassicas (MIX) were planted after wheat, and grazed by lambs in the fall seasons of 2019 to 2021. The following year, soil health, corn yield and quality were measured from plots …
Extending The Grazing Season Through The Use Of Cover Crops, D. D. Harmon
Extending The Grazing Season Through The Use Of Cover Crops, D. D. Harmon
IGC Proceedings (1997-2023)
The use of cover crops in integrated crop-livestock systems is not a novel approach but has increased in popularity over the last few years due to the renewed interest in soil conservation, nutrient cycling, and water conservation. Moreover, cool-season annual forages have the ability to extend the grazing season, reduce the need for stored or bought supplemental feedstuffs, and as a result, lower winter-feeding costs. Small grain cover crops, legumes, forbes, and annual ryegrass (Lolium multiflorum Lam.) vary in their growth distribution and can be planted alone in monocultures or planted in mixtures to take advantage of the individual …

Combining integrated crop-livestock systems under no-till management may improve soil organic matter (SOM) build up and improve soil C sequestration. Grazing cover crops appears as a possibility to combine crops and livestock in a farm system. Further SOM and soil C increase can be achieved by adding perennial grasses into crop rotations. However, the effect of grazing intensity in such systems are not fully understood. This 2-yr study investigated short-term effects of cropping system [winter cover crops-summer cotton (Gossypium hirsutum L.) and winter cover crops-summer bahiagrass (Paspalum notatum Flüggé) rotations], grazing intensity (no grazing, heavy, moderate, and light …
Soil Compaction In Cropland Pastures Used For Winter Grazing, B. F. Tracy
Soil Compaction In Cropland Pastures Used For Winter Grazing, B. F. Tracy
IGC Proceedings (1997-2023)
In the northern United States, forage availability on cool season pastures declines rapidly late in the growing season (Moser & Hoveland 1996). To supplement low forage availability in the fall and winter, producers can graze livestock on cropland pastures containing annual cover crops and crop residues. Managed properly, cropland pastures can provide livestock with abundant, high quality forage that lasts long into winter. A potential issue with cropland pastures is that presence of cattle on moist, non sod-bearing soils could lead to severe soil compaction. The objective of this particular study was to determine how winter grazing on cropland pastures …
Winter Cover Crop Impacts On Weed Dynamics In Eastern And Central Nebraska, Elizabeth Ann Oys
Winter Cover Crop Impacts On Weed Dynamics In Eastern And Central Nebraska, Elizabeth Ann Oys
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Reducing tillage in cropping systems causes weed management to be dependent on chemical and cultural methods for weed control. Over time, herbicide-resistant weeds have developed due to the continuous selection pressures from herbicides, particularly in the Midwest Corn Belt. Integrated weed management strategies, such as cover crops, can be used to mitigate some of these issues. Cover crops are primarily known for their soil health benefits, but there is evidence that cover crops can suppress weeds. However, less research has been done at the field-scale level to address cover crop impacts on the weed seedbank and aboveground weeds during the …
Benefits Of Cover Cropping Systems In Walnut Orchards As Sustainable Agricultural Practice, Ana Medic, Consuelo B. Baez Vega
Benefits Of Cover Cropping Systems In Walnut Orchards As Sustainable Agricultural Practice, Ana Medic, Consuelo B. Baez Vega
CSU Journal of Sustainability and Climate Change
In recent years walnut orchards implemented cover crops in between rows to improve soil’s quality, lessen soil’s erosion, increase organic matter, manage nutrient movement and availability, enhance water retention, and expand microbe, insect, and flora diversity. Commonly selected cover crops in California are from families Poaceae, Brassicaceae, and Fabaceae. Considerations should be made when choosing a particular cover crop mixture to enhance multiple benefits and improve sustainable practices in orchard settings. An experiment was conducted in a walnut orchard to compare functionality and benefits of three systems multi-crop, monocrop, and no vegetation cover crop system. The following components were evaluated: …

Weed control is important to optimize crop production. This study was conducted to compare the effectiveness of different methods of fall-implemented weed control strategies. These strategies included different cover crop mixes, chemical control, and mechanical control. The cover crop mixes included four different commonly-planted winter cover crops. The chemical control was a fall-applied burndown, and the mechanical control was vertical tillage. We found cover crop mixes that contained cereal rye provided the most weed control, with the chemical control being a close second. Spring oats die during the winter because of the low temperatures. The three cover crop mixes containing …

Herbicide resistant (HR) weeds pose a major challenge to continuous no-tillage (NT) dryland crop management systems. Integrating cover crop (CCs) in dryland crop rotations could suppress weeds and provide a weed management option for HR weeds in NT systems. Field experiments were conducted to investigate weed suppression potential of spring-planted CCs and their impacts on subsequent winter wheat grain yields. The CCs were oat/triticale, oat/triticale/pea, spring pea, and chem-fallow (standard) over 3 years and 2 locations in western Kansas. A weedy-fallow check was added to compare weed suppression of CCs in 2 out of the 3 years. Results showed CC …

Winter cover crops grown in rotation with grain crops can be an efficient integrated pest management tool (IPM). However, cover crop biomass production and thus successful provisioning of ecosystem services depend on a timely planting and cover crop establishment after harvest of a cash crop in the fall. One potential management adaptation is the use of short-season soybeans to advance cover crop planting date in the fall. Cover crops planted earlier in the fall may provide a greater percentage of ground cover early in the season because of higher biomass accumulation that may improve weed suppression. However, adapting to short-season …

Fall-planted forage radish (Raphanus sativus L. longipinnatus) cover crops have shown successful weed suppression and recycling of fall-captured nutrients. This research evaluated the nutrient cycling and weed suppressive benefits of forage radish cover crop mixtures to develop an integrated system for no-till sweet corn (Zea mays L. var rugosa) production that improves crop yield and soil health. Treatments included forage radish (FR), oats (Avena sativa L.) and forage radish (OFR), a mixture of peas (Pisum sativum subsp arvense L.), oats and forage radish (POFR), and no cover crop control (NCC). Subplots were assigned to …
Interseeding Cover Crops To Suppress Weeds In Corn- Soybean Rotations In Kentucky, Victoria Leigh Stanton
Interseeding Cover Crops To Suppress Weeds In Corn- Soybean Rotations In Kentucky, Victoria Leigh Stanton
Theses and Dissertations--Plant and Soil Sciences
Cover crops are typically sown between cash crops and can suppress weed emergence and growth. If cover crops are sown after cash crop harvest the system is left susceptible to weed emergence while they establish. Interseeding cover crops into a standing cash crop may limit this bare period by allowing cover crops to become established, go into dormancy, and then revive around cash crop senescence. Studies were conducted in Princeton and Lexington, KY, to determine (i) which corn pre-emergent herbicides and mixtures of herbicide active ingredients commonly used by Kentucky growers would impact interseeded cover crop density and biomass, (ii) …
