Soil Testing for Vineyards in South Dakota
Not all soils are conducive to growing quality grapes, so prospective vineyard sites should be tested before a decision is made to plant grapes. Tests can identify soils that are either too high in pH, salts, or salinity, or that are “too rich” (too high in organic matter and nitrogen) for grapes. In addition, testing before planting allows for the incorporation of nutrients—such as phosphorus—that do not move easily through the soil to plant roots.

Spring Wheat Variety Trial Results
The 2023 spring wheat reports include data from 10 locations with regional summaries.
Big Sioux River Flood Information System Sees Heavy Use During Spring 2019
The Big Sioux River Flood Information System is the result of a combined effort between the SD Department of Environment and Natural Resources, local governments, and private industry, to create a product that can be used to predict the impact of flood events in the Big Sioux River Basin.
2017-2018 Multi-State Organic Oat Variety Trial Results
The tight production margins currently present in agriculture have increased interest in growing organic oats.
Instinct HL and Nitrogen Management Effect on Winter Wheat Yield
Nitrogen (N) additives to control N losses through volatilization, denitrification, and leaching are widely used in the Midwest. Slowing the conversion of nitrogen fertilizers to nitrate may lessen leaching and denitrification losses if precipitation or soil becomes saturated.
2018 Field Plot Summaries for Wheat Disease Management Trials
The wheat disease management field experiments conducted in the 2018 growing season evaluated several experimental and commercially available fungicides for managing foliar, head or root diseases of spring wheat. Foliar and spike/head diseases incidence and severity were assessed. The field experiments were implemented at Volga Research Farm and Northeast Research Farm (NERF) near South Shore, SD. Results of the same experiment may vary between Volga and Northeast due to environmental differences between the two locations.
Sorghum Weed Control
Early competition, especially from grass, is critical for successfully controlling weeds in sorghum. There are preemergence as well as postemergence herbicides available for this crop. Early treatment provides the best control of broadleaved weeds with crop stage also being a critical factor for some postemergence treatments.
