This project was designed to evaluate inputs of various rates of compost on the yield and nitrogen status of a crop of peppers. The grower-cooperator on this project makes his own compost and, for the last two years, he has applied from three to ten tons of compost (along with other nitrogen inputs such as cover crops, feather meal and sodium nitrate) to provide for the nitrogen need of his pepper crops.
The purpose of this project was to investigate the potential of sorghum sudangrass to serve as both summer cover crop and marketable hay crop preceding no-till production of organic fall cabbage. The original stated objectives of this project were to determine best management practices for a non-leguminous summer cover crop in a no-till fall vegetable production system and to evaluate the efficacy of cover crop mid-season cutting for sale as hay. Based on the results of a 2003 field trial, these objectives were narrowed to the following:
Several researchers (Francis et al., 1990; Murray and Butler, 1994; Poudel et al., 2000) have suggested farmer participatory research methods for problem identification, research design, and implementation of research results in developing production strategies for enhancing agricultural sustainability and environmental quality.
Sustainable agriculture and food systems depend upon the efficient use and recycling of nutrients in order to minimize dependence on non-renewable resources - such as fossil fuels and mined minerals - and to prevent contamination of ground and surface waters. Yet, as modern food systems continue to industrialize and globalize, environmentally sound nutrient cycling becomes increasingly difficult because of the massive scale and concentration of agricultural production enterprises, food processing facilities, distribution systems, and food service institutions.
The size and growth of organic farming has stimulated considerable discussion and speculation. Farmers, agribusinesses, policy-makers, public interest groups, educators, researchers and investors-all need reliable information on organic agriculture to make informed decisions about business strategies, teaching and research agendas, and institutional policies. Statistical analyses of organic farming contribute crucial information for these decisions.
There are two obvious barriers organic producers face when they consider on-farm processing. The first is psychological. On-farm processing can appear intimidating and beyond reach, on one hand; on the other, it may seem unnecessary to someone who is already “adding value” by raising crops or livestock organically. The second barrier—a more pragmatic one—is the lack of good, producer-friendly information on small-scale organic processing and handling.
Habitat management to enhance biological control in cultivated crops is an increasingly common method of pest control in both annual and perennial cropping systems. Examples of this approach include use of windbreaks or hedge rows to prompt build-up of natural enemies around crop edges, planting of insectary seed mixes as cover crops in perennial crops, or management of natural ground cover (e.g., via mowing frequency, strip mowing, or selective herbicide use) to enhance build-up of natural enemies.
