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.

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.

Conserving and restoring pollination services in organic farms of Yolo and Solano Counties, Northern California

Native bee pollinators link natural habitats with agricultural areas. Native bee populations may rely on natural habitats to provide forage and nesting resources during part of the year, and agricultural areas the rest of the year. Native bee pollinators may provide pollination services in both areas, and may in turn depend on both. Thus problems in one area could affect the other.

Increasing Organic Farmer Access to Relevant and Practical Research-Based Information

The principal objective of this project was to make a greater proportion of relevant and practical research-based information available to organic farmers. Experienced organic farmers were specifically targeted. In the original proposal, NCAT planned to create a quarterly publication featuring abstracts of relevant research gleaned from the literature. Emphasis was to be placed on recent, cutting-edge research on a broad range of topics pertinent to organic production and marketing.

Biological control of Delia sp. in cole crops with rove beetles, Aleochara sp. (Part 2)

The objective of this study was to examine the use of rove beetles, Aleochara spp., for the biological control of root maggots, Delia spp. in organic cole crops. We were interested in manipulating Aleochara numbers by either conservation strategies or by augmentative releases of mass-reared Aleochara bilineata. 

Impact of Disease Suppressive Composts on Organic Vegetable Quality Composition and Yield

The goal of this research was to initiate studies on compost effects on severity of common soil borne diseases and to characterize changes plant growth due to improved nutrient availability and soil microbial activity with compost application in organic production systems. 

Project Objectives

-Analyze several animal manure-based, organic-approved compost products for suppression of important soil-borne pathogens of vegetable crops in the Northeast

-Determine applicability of a farmer-based test kit for assessment of compost maturity to predict suppressiveness

Soil Nutrient Balancing in Sustainable Vegetable Production

The purpose of this project is to determine whether an unfavorable balance among soil 

A comparison of antibiotic susceptibility patterns for Staphylococcus aureus in organic and conventional dairy herds

Mastitis is considered to be the most costly disease affecting the dairy industry with annual losses in the United States exceeding $2 billion (Philpot, 1984). Losses stem from milk discard, drug costs, veterinary care, increased labor, and premature- culling. Staphylococcus aureus is one of the most important pathogens causing intramammary infections in dairy cattle (Gonzalez et al.,1988) and continues to be one of the major causes of mastitis in dairy herds worldwide (Barkema et al. 1998, Gonzalez et al. 1988, Nickerson et al. 1999, Osteras et al. 1999, Sol et al.

Evaluation of Alternative Cultivators for Vegetable Production

The brush hoe cultivator (Bartchi Fobro Co., Switzerland) was evaluated for weed control cool-season vegetables in the Salinas Valley. The brush hoe was compared with conventional vegetable cultivators in seven on-farm trials. The brush hoe cultivated closer to the seed row than the conventional cultivators used by the growers. It left uncultivated strips 2 7/8 inch wide while conventional cultivators generally left uncultivated strips four inches wide. The brush hoe provided comparable or improved weed control over conventional cultivation.

A grower-managed biorational program for artichoke pests (BIORAPP) on the north central California coast

A native egg parasite, Trichogramma thalense, was mass-reared in the laboratory and released a maximum of thirteen times against the eggs of the artichoke plume moth (Platyptilia carduidactyla) in three 5-acre biointensive artichoke production fields on the northern Santa Cruz/San Mateo County coast in 1998 and again in 1999-2000.
