The educational materials listed on this page are about Organic Agriculture.
Organic agriculture integrates “cultural, biological and mechanical practices that foster cycling of resources, promote ecological balance, and conserve biodiversity.” Organic and sustainable agriculture often include the use of cover crops, crop rotation, use of tools and machinery for weed and pest management, and conservation tillage. Synthetic fertilizers, sewage sludge, irradiation and genetic engineering may not be used for food to be certified and labelled USDA organic. Organic livestock must have access to the outdoors and be “fed 100 percent certified organic feed, managed without antibiotics, added growth hormones, mammalian or avian byproducts, or other prohibited feed ingredients.” SARE has many helpful reads including Transitioning to Organic Production, which addresses conversion strategies, organic farming production practices, marketing approaches and federal organic standards for certified organic crop and livestock. SARE’s Crop Rotation on Organic Farms reviews how rotating crops improve soil quality and health and help manage pests, diseases, and weeds.

Pest Exclusion Systems for Pest Management in Vegetable Production Across the Southeast
In organic vegetable production, and in situations where farmers are seeking to reduce chemical applications, Integrated Pest Management (IPM) strategies are recommended to exclude pests in both opens fields and in high tunnels. The principles of pest exclusion involve separating the insect pest from the host plant and protecting the crop at a specific growth stage. Careful planning of both materials selected and management design are important to keeping pests out of a cash crop. This bulletin provides data and information from on-farm demonstrations on the use of pest exclusion systems. Pest exclusion systems use shade cloths as a barrier around high tunnels, low tunnels and hoop houses to exclude insect pests.

High Tunnel Pest Exclusion System
Insect pests are one of the major problems in organic production systems. Organic IPM practice consists of a three-tiered approach consisting of systems-based practices, mechanical tactics, and biorational insecticides. Mechanical tactics encourage the use of physical barriers for pest exclusion. This bulletin provides preliminary research data and field observations about the success of shade cloths, or high tunnel pest exclusion (HTPE) systems, as a more permanent barrier system around the high tunnels.
Soil Management Using Cover Crops in Organically Managed High Tunnels
In southern climates, high tunnels are typically used for season extension in the spring, fall, and winter. In the hot summer months, if no shade cloth is used to cover high tunnels, it can be difficult to grow anything but the most heat tolerant crops, and it can be uncomfortable to work in tunnels due to the heat. This is an excellent time to incorporate a cover crop, between the late spring and early fall crops. Many cover crops species are adapted to hot southern summers and perform well in high tunnels.
High Tunnel Pest Exclusion System Part II
With the increasing demand for local foods across the Southeast, an increasing number of beginning, as well as experienced producers are producing vegetable crops in high tunnels for direct and whole sale markets. From the insect management perspective, it is extremely critical to adopt pest prevention practices; the high tunnel pest exclusion (HTPE) system is one of the best relatively-low cost pest preventive practices available to producers in the Southeast. This HTPE technology uses a variety of shade cloths for a relatively permanent pest prevention strategy. This bulletin provides information on the use of HTPE systems on the farm.
