Interseeding of Cover Crops to Improve Cover Crop Establishment and Performance
This project will develop and evaluate new cover crop planting strategies to improve cover crop establishment after late harvested crops. Cover crops add organic matter to the soil, improve soil tilth, capture soil nitrate that is susceptible to leaching into ground water, fix nitrogen (if legumes are planted), and suppress winter weeds. But here is […]
Estimating Plant-Available Nitrogen RElease From Cover Crops
A key benefit of cover crops is their ability to supply plant-available nitrogen (PAN) for the following crop. PAN consists of ammonium-N + nitrate-N. The PAN provided by a cover crop can replace purchased N inputs such as fertilizer, compost, or manure. But, to take advantage of this benefit, you need to know how to […]
Influence of Contrasting Soil Moisture Conditions on Carbon Dioxide and Nitrous Oxide Emissions from Terminated Green Manures
Carbon dioxide (CO2) and nitrous oxide (N2O) emissions from decomposing legume green manures largely depend on soil moisture. A potential management to mitigate N2O emissions could be to incorporate legumes during dry periods based on the short‐term rainfall forecast. The present mesocosm study was designed to examine the impact of soil moisture due to different […]
Interseeding Cover Crops into Twin Row Soybean
A trial was established to evaluate the soybean yield response to interseeding cover crops into growing soybean compared to soybean yield without interseeding cover crops (control). Four treatments of cover crop and three planting dates were established using a randomized complete block design with four replications.
Timing of Cover Crop Rye Termination in No-Till Soybeans
The objective of this study was to determine the effects of timing of cover crop cereal rye termination with herbicides on no-till soybean grain yield.
Annual cover crops for managed and wild bees: Optimal plant mixtures depend on pollinator enhancement goals
Agricultural intensification and landscape simplification have reducedflowering plant abundance and diversity worldwide, with subsequent negative effects on pollinators. To mitigate these effects, research and conservation have focused on incorporating flowering plants into agricultural landscapes through on-farm natural areas or flowering crops. However, while cover crops provide numerous agroecosystem services, they have received little attention for […]
Intersowing Cover Crops into Standing Soybean in the US Upper Midwest
Nutrient losses and soil erosion after soybean (Glycine max (L.) Merr.) harvest are common in the US Upper Midwest. Cover crops need to provide adequate growth and cover to prevent soil degradation throughout the winter and early spring months. The objective of this study was to determine the establishment of intersown cover crops and their […]
MCCC-North Dakota Annual Report April 2018 to February 2019
Multiple studies reported to the Midwest Cover Crop Council showing best practices for cover crop use in North Dakota row crop operations.
AGRONOMIC STUDIES OF FORAGE BRASSICAS AS FULL-SEASON AND COVER CROPS FOR GRAZING IN NORTH DAKOTA
Annual forages represent a good feed resource to extend the grazing season into fall and winter, providing a good quality forage for the livestock, allowing more efficient use of rangeland, and improving soil properties. Many species in the Brassicaceae family are used as forages for grazing. Forage brassicas have high forage yield, high nutritive value, […]
Weed suppression and soybean yield in a no-till cover-crop mulched system as influenced by six rye cultivars
Cover crop mulches have been successful in reducing weed severity in organic soybeans. This study examined six rye cultivars (SRCs) used as cover crops to determine which were most adapted for use with a roller–crimper in the southeastern U.S. To be an effective mulch, a rye cultivar must produce high biomass and reach reproductive growth […]
Critical Period for Palmer Amaranth Control and Cultural Control of Palmer Amaranth in Pickling Cucumber Systems with Cover Crops and Row Spacing
Studies were conducted in North Carolina to determine the effect of cereal rye and oat cover crops with or without herbicides on Palmer amaranth density and growth in no-till pickling cucumber. Cover crop treatments (cereal rye, oat, and fallow) were evaluated alone and in combination with herbicide treatments for effects on Palmer amaranth control and […]
Effects of Cover Crops, Compost, and Vermicompost on Strawberry Yields and Nitrogen Availability in North Carolina
Summer cover crop rotations, compost, and vermicompost additions can be important strategies for transition to organic production that can provide various benefits to crop yields, nitrogen (N) availability, and overall soil health, yet are underused in strawberry (Fragaria ×ananassa) production in North Carolina. This study was aimed at evaluating six summer cover crop treatments including […]
Winter Annual Cover Crops
Winter annual cover crops have been used in rotation with summer crops for many years in North Carolina, but now there are some interesting new applications of this practice. Early experiments date from the 1940s and show several important benefits of planting winter annual cover crops, chief among them erosion control, addition of nitrogen (N) […]

Summer Cover Crops
There is growing interest in the use of short-season summer annual legumes or grasses as cover crops and green manures in vegetable production systems. Cover crops can provide a significant source of nitrogen (N) for subsequent crops; reduce erosion, runoff, and potential pollution of surface waters; capture soil N that might otherwise be lost to […]
Planting Date Impacts on Soil Water Management, Plant Growth, and Weeds in Cover‐Crop‐Based No‐Till Corn Production
Low input and organic farmers are utilizing cover crop mulches in corn (Zea mays L.) production. Corn planting is typically delayed to improve the efficacy of mechanical termination with roller‐crimpers. During the late spring, as cover crops are allowed to grow to maximize biomass production, soil moisture reserves can become depleted, thereby directly impacting early […]
Brassicas as Biofumigants for Controlling Soilborne Organisms in Potato Production for Upstate New York and Northern Pennsylvania
Soilborne organisms are becoming more difficult to control due to pathogen resistance and restricted use of some chemicals. The cost of chemicals is also becoming a concern. Brassicas are of interest in that they produce glucosinolates, which can be converted to chemicals with biofumigant activity. In addition to providing some disease control, growing and incorporating […]

TERMS OF SERVICE: ENHANCING ESTABLISHMENT AND GROWTH OF INTERSEEDED COVER CROPS
Winter cover crops provide a suite of benefits but their use is limited because there is often not enough time after harvesting crops in the fall to establish cover crops before winter. Problems with establishment may be overcome by interseeding, where cover crops are seeded between rows of cash crops prior to harvest. Interseeded cover […]
Corn Density Effect on Interseeded Cover Crops, Weeds, and Grain Yield
A field experiment was conducted at three sites (New York, Pennsylvania, and Maryland) in 2016 to test the effects of drill interseeding a cover crop mixture consisting of cereal rye (Secale cereale L.), annual ryegrass (Lolium multiflorum Lam.), hairy vetch (Vicia villosa Roth), and red clover (Trifolium pratense L.) into organically managed corn (Zea mays […]
