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. Urease inhibitors like Agrotain Ultra slow the conversion of urea to ammonia, lessening potential volatilization losses. Nitrification inhibitors like Instinct HL are designed to slow the activity of Nitrosomonas bacteria, which convert ammonium to nitrites; this may reduce the risk of N losses due to leaching and denitrification. Long-term yield and economic response to these additives is highly dependent on the amount and timing of precipitation events. Therefore, a winter wheat nitrogen management study was conducted to evaluate the influence of Instinct HL (nitrapyrin- nitrification inhibitor) and Agrotain Ultra (N-(n-butyl)-thiophosphoric triamide(NBPT)- urease inhibitor/volatilization reducer) on wheat grain yield.
Instinct HL and Nitrogen Management Effect on Winter Wheat Yield
Introduction of salt-impacted soils in South Dakota for landowners.
The SDSU Native Plant Initiative aims to improve our understanding of South Dakota’s native plants, including which ones are best-suited for restoration and production. This information will help guide stakeholders in matching native species to desired restoration outcomes.
As the temperature drops, don’t forget to check on your stored grain. Although most of the South Dakota grain harvest was sufficiently dry this year, we still need to watch grain storage temperatures and conditions.
