Nutrient analysis of organic strawberries: effect of cultivars and mycorrhizal inoculations

Objectives 1. Demonstrate the relative nitrogen performance of standard California cultivars grown under organic management. 2. Determine if a commercial arbuscular mycorrhizae (AM) inoculant could provide mineral nutritional benefit, especially on phosphorus, to the cultivars being tested in the first objective. 3. Provide information that will aid organic strawberry producers in fertility management.

Statistical review of California's organic agriculture

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.

Plant mobilization of trace organochlorine residues in vegetable cropping systems

Soil testing has long been a part of Organic Certification. As part of the certification process, each grower must submit soil tests for lab analysis. The soil is subjected to chromatography tests to determine the extent of contamination by organochlorine insecticides. These compounds classify a wide range of noxious agricultural pesticides, many with half lives exceeding twenty years. Unfortunately for conventional and organic growers, even at hardly detectable levels these contaminants are finding their way into agricultural products.

On-farm analysis of soils, crop performance and profitability of organic, integrated and conventional apple production systems

In April 1994, a high density commercial orchard of `Golden Delicious' apples on EMLA.9 rootstocks was planted on four acres of a 35-acre apple farm in the Yakima Valley of Washington State. The farm is managed by two brothers, Andy and Eric Dolph, who decided with our help to set aside a portion of their farm and examine the sustainability of three different apple production systems: organic, integrated (i.e., low-input), and conventional.

Farm Made: A Guide to On-Farm Processing for Organic Producers

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. 

Fundamentals of Organic Farming and Gardening: An Instructor’s Guide

In 2006, Georgia Organics developed an organic farming curriculum guide that was extremely popular—almost 1,000 copies were distributed to instructors across the nation within a year. The curriculum was also added to the Georgia Department of Education’s Agricultural Education Curriculum CD, distributed annually to all high school agriculture and science educators in the state.
 

Maximizing shareholder retention in Southeastern CSAs

Athens, GA - Retaining shareholders is a difficult problem for many farmers operating Community Supported Agriculture (CSA) programs, and the time and energy spent recruiting new shareholders can be a strain, expecially in regions where the CSA "tradition" is not well established and understood among potential subscribers. Shareholders' pre-subscription expectations and post-subscription appraisal of their experiences is a valuable tool for evaluating and improving upon this unique farmer/consumer relationship.
 

Enhancing biological control in mating disruption and organic pear orchards by understory management

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.

Evaluation of the Efficacy of Predatory Mites in Controlling Pests of Cultivated Mushrooms in Organic Mushroom Houses

The following species are the most common predatory mites in Polish mushroom houses, in which Agaricus bisporus is cultivated: Arctoseius semiscissus, A. cetratus, Dendrolaelaps fallax (Kropczyfiska-Linkiewicz 1984), and Parasitus sp. (Lewandowski, unpubl.). Species composition of mite predators of mushroom houses with oyster mushroom (Pleurotus ostreatus) is not known yet. Predatory mites are obviously of the most interest in mushroom pest control in the organic mushroom houses.

Bat Houses for Integrated Pest Management-- Benefits for Bats and Organic Farmers: Phase I

Bats are helpful to farmers, as they consume large quantities of insect pests, but many bat species are declining due to loss of roost sites. Farmers can help bats by providing new roosts in the form of bat houses while at the same time benefiting from batsí pest reduction services. However, as much of the evidence for batsí roles in insect biocontrol is anecdotal, further studies are needed to better document batsí contributions to agriculture.
