Researchers Integrate Renewable Energy into Greenhouses to Make Farms More Sustainable

BOONE, North Carolina- With limited land and shortened growing seasons in the mountains of North Carolina, Ok-Youn Yu, an associate professor and assistant chair of Appalachian State University’s Department of Sustainable Technology and the Built Environment, saw potential in using greenhouses to combat hunger while increasing farmer’s profits and sustainability. Through a Southern Sustainable Agriculture […]

Grafting Can Help Control Diseases in Organic High Tunnel Tomatoes

GAINESVILLE, Florida – Grafting can help control diseases in organically grown high tunnel tomatoes, according to the results of a University of Florida study. In the study, funded by a Southern Sustainable Agriculture Research & Education (SSARE) On-Farm Research Grant, specialty tomatoes grafted onto two disease-resistant rootstocks effectively managed Fusarium wilt and improved the overall […]

Cover Crops Have Benefits in High Tunnels

GLENWOOD, Georgia – Barley and hairy vetch growing vigorously in a high tunnel at Lola’s Organic Farm in southeast Georgia were going to seed. It was mid-April. Time to mow and prepare the soil for the summer’s cash crops: ginger and turmeric. Since last year, couple Jennifer Taylor and Ron Gilmore – USDA certified organic […]

Texas Producer Finds Asparagus Can Be Viable in the South Nearly Year-Round

LYFORD, Texas — A south Texas producer, interested in increasing the diversity of crop production for local farmers, has found that asparagus can be grown in the Texas heat practically year-round by mimicking the “die-back” that occurs in the plants during dormancy in colder climates. With a Southern Sustainable Agriculture Research & Education (SSARE) Producer […]

Berries Thrive in High Tunnels, But Be Aware of Pests, According to University of Arkansas Study

FAYETTEVILLE, Arkansas – A University of Arkansas study has found that using high tunnels in berry production can increase yields, extend the harvest season, and improve fruit quality compared to field production. However, care must be taken to manage pests. In the Southern Sustainable Agriculture Research & Education (SSARE)-funded project (LS12-250), “Extending the Market Season […]

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.

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.

Physical Pest Exclusion with Shade Cloth

Alabama farmer Will Mastin describes his experience using shade cloth on a high tunnel to protect crops from some pests. Mastin’s trials with shade cloth were funded by a grant from Southern SARE. Throughout his project, Mastin worked with Alabama Extension entomologist and Southern SARE state coordinator Dr. Ayanava Majumdar to improve the shade cloth technology. […]
