Research on the use of controlled-release fertilizers (CRF) in California vegetable production has been conducted for more than 30 years. Since Lorenz et al. (1972) evaluated CRF for potato ( Solanum tuberosum ), tomato ( Solanum lycopersicum

Land application and landfilling are the most common destination for biosolids in the United States. When properly treated and managed in accordance with the existing state and federal regulations and standards, biosolids are safe for the environment and human health. Application of biosolids in vegetable production as an organic amendment to soils can increase plant growth and produce comparable crop yields with less inorganic nutrients than a standard program of commercial synthetic fertilizers. No application rate of treated biosolids alone will produce crop yields equivalent to commercial fertilizers. Biosolids may be used in conjunction with fertilizer thus lessening the application rate required. The major obstacles to public acceptance are issues concerning water pollution, risk of human disease, and odors. Additionally, heavy metals are an issue of bias with public perception. To ensure safe use of biosolids to a vegetable production systems the agronomic rate (nutrient requirement of the vegetable crop grown) should be calculated before application for the specific crop.

A research and extension program for increasing vegetable production in southeastern Virginia was launched by Virginia Cooperative Extension in 1997. The launch was triggered by the construction of a shipping point market in Southampton County. First, a market window study identified target crops and the harvest period when they could be most profitably marketed. Target crops were watermelon, sweet corn, snap beans, muskmelon, bell pepper, and pumpkin. Second, a technology transfer program was formulated that emphasized demonstrations, field days, classes, and workshops. On-farm demonstrations of intensive vegetable production techniques formed the foundations of the extension effort and focused on drip irrigation, plastic mulch on raised beds, water and nutrient monitoring, honey bee pollination, and integrated pest management (IPM). “Growing Vegetables for the Commercial Market” was the title of a short course offered in partnership with the local community college. Sixty-five graduates completed the course in 1999. Workshops were offered on farm labor, marketing, irrigation, and production techniques. On-farm research was conducted in support of the emerging vegetable industry. The focus was on sweet corn IPM, variety trials for watermelon and pumpkin, and soil and plant analysis. Information was made available to growers through a bimonthly newsletter, an annual bulletin entitled Commercial Production Recommendations, and VCE postings on the World Wide Web.
