Cover Crops 2019: What to Plant When
As many Midwest producers look to cover crops to build soil health and provide supplemental forage after a soggy spring, many questions are arising regarding management decisions, specifically, species selection and planting timing.
Wet Feet in Wheat
Given the widespread wet conditions present this spring, there are many areas in winter wheat fields with both ponding and saturated (or waterlogged) soils. Producers may want to consider soil conditions and evaluate extended weather forecasts when deciding whether or not to retain a winter wheat this spring.
Investigation of Soybean Seed Treatment and Inoculant in Southeastern SD, 2018
Soybean seed treatment products are widely utilized by many farmers in southeastern South Dakota and the surrounding area. These products often consist of an insecticide/fungicide combination, and/or inoculant that is mixed and placed on the seed as a pre-treatment before the grower plants the crop.
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.
Winter Survival and Spring Stand Counts in Winter Wheat
Every winter, growers are curious if their wheat field will survive the winter. Not enough snow cover during the coldest days, spring flooding, and ice injury are the main reasons for plants to die. The only way to get a true assessment of winter survival is to scout the field in the spring.
Plant Growth Regulator Reduces Height, Lodging in Oats
With the goal of reducing lodging in oats, SDSU Extension and a research team initiated a multi-location trial in 2018 growing season to study the effects of plant growth regulator (PGR) on oat performance.
Effects of Snow on Wheat
Even though snow that comes with the onset of cool temperatures can be a nuisance for our daily activities, it can benefit a winter wheat crop a great deal.
