Exploring a Biological Control Method for Organic Rice in Southern Florida

BELLE GLADE, Florida – For nearly a century, farmers in southern Florida have been using parasitic wasps, rather than pesticides, as the go-to pest management method in sugarcane. Now University of Florida researchers are hoping to perfect the use of biologicals in organic rice production. In the Everglades Agricultural Area, confined around Lake Okeechobee, sugarcane […]

Legume Cover Crops Have Potential as a Nitrogen and Forage Source in Semi-arid West Texas

SAN ANGELO, Texas – Farmers in west Texas are eyeing legume cover crops as a nitrogen and forage source to fill fallow periods between dryland, no-till wheat and cotton crop rotations. But finding the best fit for the area’s environmental challenges is proving tricky. So Texas A&M University researchers are working with farmers to develop […]

Warm Season Limpograss Bridges the Forage Gap for Fall Grazing in Florida

MARIANNA, Florida – For Southeast ranchers interested in grazing their beef cattle year-round, winter is the most challenging season for finding supplementing feed after warm-season grasses, like bahiagrass, decline in the fall, but before cool-season forages (oats or rye) are ready in the winter. University of Florida researchers have found a perennial grass that will […]

Studying the Impact of Conservation Plantings on Insect Pests and Their Predators

BATON ROUGE, Louisiana – Conservation plantings, through various stewardship programs, do well to provide a myriad of benefits. These range from controlling erosion, to improving water quality, to promoting healthy soils. However, the impacts of such strategies on cash crop pests and the natural enemies that target them is less known. Louisiana State University researchers, […]

Exploring Conservation Tillage Systems for Southern Pea, a Long-forgotten Staple Making a Comeback

MOUNT OLIVE, North Carolina – Rural farmers in eastern North Carolina are rediscovering the versatility, hardiness and protein-packed powerhouse of Southern pea – a long-forgotten household food staple. “What was once old is now new again,” said Jason Davis, assistant dean of the School of Agriculture and Biological Sciences at the University of Mount Olive. […]

Diversifying Small Farms with Cereal Grains

FOREST, Virginia – Virginia farmer Michael Grantz is testing what it takes to incorporate cereal grains into a small-scale, diversified vegetable and cut flower farm for soil health as a cover crop and a value-added product for local markets. Grantz has managed a quarter acre plot of wheat and rye on he and his wife’s […]

Louisiana Farmer Using Drone Technology to Maximize Nitrogen Efficiency in Row Crops

LAKE PROVIDENCE, Louisiana – Corn and cotton crop producer Nolan Parker is taking to the skies to decrease nitrogen runoff from commodity farms along the Mississippi River. The young farmer, who is a Federal Aviation Administration (FAA) certified remote pilot and works routinely with unmanned aerial systems (UAS), combined drone technology with variable rate nitrogen […]

Exploring Warm Season Grasses for Parasite Control and Performance in Sheep

HIDDENITE, North Carolina – A North Carolina livestock producer is exploring the use of native warm season grasses as forage for Katahdin Hair sheep as a way quickly bring the animals to market weight, and for better parasite control. Lee Holcomb of LeeDer Farm, situated in a rural area just north of Charlotte, is establishing […]

Intercropping Cowpea with Vegetables Can Increase Yields

GREENSBORO, North Carolina- Intercropping cowpea with vegetable crops can increase yields up to 50% according to a new report from the Southern Sustainable Agriculture Research and Education program. Cowpea is a nitrogen-fixing legume originally domesticated in Africa. Known for its black-eyed peas that are common in southern cooking, it has a high tolerance for sandy, […]

Organic Control of White Mold in High Tunnels

The fungus Sclerotinia sclerotiorum infects many of the cool-season crops produced in Kentucky. This SARE-funded video presents information on the high tunnel production system most commonly used in Kentucky; the disease cycle of S. sclerotiorum; and two control tactics compatible with national organic standards, solarization and biofumigation.

Cover Crops and Biodegradable Mulches for Weed Control

AUBURN, Alabama – High biomass cover crops are effective in controlling weeds in vegetable production, while contributing to higher produce yields, Auburn University researchers have found. In addition, pre-emergence herbicide applications can be eliminated from weed management programs in the presence of heavy residues from cover crop mixtures. Through a Southern Sustainable Agriculture Research and […]

Researchers Recommend New Strategies to Suppress Southern Potato Blight

PAINTER, Virginia – Earlier planting dates coupled with disease-tolerant cultivars of potatoes are recommended strategies to suppress southern potato blight, according to Virginia Tech researchers. The fungal disease, caused by the soil born pathogen Sclerotium rolfsii, affects the stems of the plants and produces lesions on the tubers, impacting quality and yields. In a Southern […]

Agroforestry an Alternative for Farmers Transitioning Away from Tobacco Production

BEREA, Kentucky – A Kentucky farmer, exploring alternatives for tobacco production, has found that elements of an agroforestry system may prove viable to increasing farm profitability and providing environmental benefits. Through a Southern Sustainable Agriculture Research and Education (SSARE) Producer Grant, Matthew Wilson of Rindlewood Farm studied the feasibility of incorporating sweet sorghum and pasture […]

Exploring Alternative Methods for Controlling A Major Pest in Sweet Sorghum

LEXINGTON, Kentucky – University of Kentucky researchers are exploring alternative methods for controlling sugarcane aphid in sweet sorghum, a major crop for farmers in the state. Through a Southern Sustainable Agriculture Research and Education (SSARE) On-Farm Research Grant, entomologist Nathan Mercer and his colleagues are studying a combination of parasitoids and insecticidal soaps as a […]

Low-external-input Sustainable Agriculture Provides Environmental Benefits and Economic Gains in Rice Production

STARKVILLE, Mississippi – Rice, for all of its importance as a global food staple, can have a number of environmental tradeoffs. Intensively managed, the crop can put a strain on natural resources, particularly soil and water. But a more sustainable production system may enhance environmental quality at an economic gain for the farmer, based on […]

The Performance of Cover Crops in Minimally Tilled Forage-based Grazing Systems

In a Southern SARE-funded Graduate Student Grant (GS15-152), “Evaluation of Winter Annual Cover Crops Under Multiple Residue Management: Impacts on land management, soil water depletion, and cash crop productivity,” Texas Tech University researchers investigated five cover crops species as potential complements to a warm-season beef-stocker grazing system. The impact of the project was two-fold: Stabilize the soil surface from excessive wind erosion and desiccation; and strengthen rural communities by ensuring the persistence of profitable agriculture in the region.

Using Multispectral Imaging Technologies to Maximize Yields in Sugarcane

HOUMA, Louisiana – When it comes to profitable sugarcane, the goal of every grower is to achieve the highest possible sucrose yield at the lowest production cost possible. Sugarcane yields correlate with nitrogen application, and as producers continue to get squeezed between decreasing acreage and higher input costs, such as fertilization, they are looking for […]

In Drought-stricken Texas, Researchers are Finding Water Conservation Solutions in Cover Crops

LUBBOCK, Texas – In the Texas High Plains, a region where the water-depleting Ogallala Aquifer endangers productive agriculture, and hot, arid winds erode soils and rob them of nutrients, cover crops offer a useful option to livestock producers. In a two-year graduate student study at Texas Tech University, funded through the Southern Sustainable Agriculture Research […]

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.
