Buckwheat Cover Crop Handbook
Buckwheat has been used to suppress weeds on Northeastern farms for 400 years. This handbook outlines how to use buckwheat as an economical weed-control tool, with recommendations based on extensive grower surveys, original research and on-farm trials.
Influence of Cover Crops on Insect Pests and Predators in Conservation Tillage Cotton
Results of a two-year research project to determine the impact of several cover crops on pest and predator insects in conservation tillage cotton.
A Sunn Hemp Cover Crop for Soil Health and Nematode Management
These University of Hawaii fact sheets and virtual field day explain how to use sunn hemp as a cover crop to control weeds, nematodes and other pests, add soil nutrients, prevent erosion, and contribute to a more robust and complex community of beneficial nematodes.
Winter Annual Weed Suppression in Rye–Vetch Cover Crop Mixtures
Zachary Hayden received an NCR-SARE Graduate Student Grant to evaluate the relative effects of rye, hairy vetch, and rye-vetch mixture cover crops on the biomass and density of winter annual weed communities. This SARE research supports that winter cover crops composed of rye or vetch (or both) can significantly suppress winter annual weeds.
Invertebrate Pests and Their Natural Enemies in Conservation Tillage Cropping Systems
In this webinar by Dr. Mary Barbercheck and Maggie Douglas, learn the basics about key early-season insect and slug pests that can pose problems in conservation tillage systems with high amounts of cover crop residues and how crop management practices can help reduce pest damage. Also, learn about ongoing research into naturally-occurring predators of early season insects and slugs and how best to conserve them.
Optimizing Weed Suppression and Nutrient Use Efficiency in Cover Crop-Based No-Till Organic Corn
In this webinar, Hanna Poffenbarger of the University of Maryland and Steven Mirsky of the USDA-ARS Sustainable Agriculture Systems Lab discuss optimizing cover crop mixture composition and manure application to achieve weed suppression and adequate, efficient nitrogen delivery in a cover crop-based no-till corn system.
Beyond Black Plastic
While the use of black plastic is allowed within organic agriculture, it is inherently unsustainable as it is a petroleum-based product and difficult to recycle.
This 24-page guide looks beyond plasticulture and evaluates the effects of different mulch systems on soil quality and fertility, weed control, yields and waste production, and profitability for small to mid-size vegetable farms.
