Long residual pre-emergent or early post-emergent herbicides may cause stand reduction or complete cover crop failure of cover crops. This situation, depending on efficacy of the herbicide can both affect in-season and/or post-harvest cover crop establishment.
Agricultural trade agreements were first established in the General Agreement on Tariffs and Trade (GATT), legal treaty signed initially by 23 nations in 1947. The purpose was to promote international trade by reducing barriers such as tariffs.
Dicamba off target movement created disagreements between many. This occurred in South Dakota between farmers, farmers and companies, farmers and university weed scientists and companies with regulatory agencies.
Short growing seasons in South Dakota create difficulty for field activities following row crop harvest in the fall. Some crop producers in the state occasionally grow soybeans with varying maturity ratings for two major reasons: 1) to spread out the harvest resources in the fall, and 2) to avert any unpredicted weather circumstances such as early frost, mid-season hail occurrences, drought conditions, etc.
When precision agriculture comes into a conversation a few questions arise. Three of those questions might be: What is precision agriculture? How does precision agriculture make our farm more profitable? What do I do with all this data?
The South Dakota Department of Agriculture adopted the 2018 federal label for the dicamba herbicides: XtendiMax, FeXapan and Engenia. There are substantial changes from the 2017 label-especially in regards to weather.
The South Dakota Department of Agriculture has labeled Engenia, Fexapan, and Xtendimax for postemergence use on Xtend “dicamba tolerant” soybeans for the 2018 growing season. There are several changes to the label over last year.
SDSU Extension conducted a study during the 2016 growing season at five Eastern South Dakota sites to evaluate the effects of added N fertilizer (as urea) on soybean yields. The study was established at the SDSU Northeast Research Farm and four on-farm cooperators’ fields in Clark, Kingsbury, and Minnehaha (2 sites) counties.
Crop performance testing results are released annually through the activities of SDSU Extension and the South Dakota Agricultural Experiment Station at SDSU.
Soybean harvest is nearing as most, if not all, soybeans have turned color or dropped leaves. Fall time is the best time of year to sample and test the soil for soybean cyst nematode (SCN), the number one silent yield robber of soybean.
