    Soggy Soybean Fields: Late Planting Considerations

    With the longest day of the year in the rearview mirror, some soybean producers in the southern part of the state find themselves in an uncomfortable situation. Although some sources report that South Dakota soybeans are 100% planted, areas in Bon Homme, Hutchinson, Douglas, and Charles Mix counties and the surrounding region are still struggling to get a soybean crop planted due to frequent rain events.

    S.D. Riparian Buffer Classification Program: Signup deadline Oct. 15

    During the 2017 SD Legislative Session, Governor Dennis Daugaard signed into law Senate Bill 66 (SB 66), also known as the “buffer strip” bill. Essentially, the bill provides an incentive for landowners to plant perennial vegetation on land adjoining qualified lakes, rivers, or streams via a property tax adjustment in order to improve water quality.

    Drought Stress Symptoms in Soybean

    Soybeans in South Dakota are in their moisture-critical reproductive stage. Drought stress during this growth stage can significantly impact yield, so here are some things to look for. When soybean is drought stressed, the leaves will flip over to show their silvery-green undersides. This is a defensive mechanism they use to reflect more light, reducing the amount of sunlight the plant takes in through its leaves.

    Watch for Grasshopper Population Outbreaks

    Our early prediction of grasshopper populations was that there would be areas where outbreaks would be possible during 2018. We are just starting to receive reports of grasshopper populations that are exceeding recommended thresholds throughout central South Dakota as well as areas in northeast South Dakota that haven’t received much rain this year.

    Missouri Confirms 6-Way Herbicide Resistance in Waterhemp

    Herbicide resistance has been an issue for the management of weeds for many years. In South Dakota, resistance in several weed species to multiple sites of action (SOA) of herbicides have been documented. However, the newly published 6-way resistance that is present in Missouri waterhemp has not yet been observed in South Dakota.

    Project to Study Soil Health Economics in South Dakota

    Soil degradation has become one of the most pressing global issues, because of its adverse effects on world food security, environment and quality of life. Farm management practices such as conventional tillage and monoculture cropping systems can directly damage soil health by causing erosion, carbon loss and nutrient depletion.

    Road Salt & Water Quality: Growing Concern in Some Northern States

    I recently came across an article from the Associated Press addressing road salt and the nation's waterways. Many of you may have seen the article too as a number of local media outlets elected to carry it. While road salt is almost a necessity in our part of the country, it can come at a cost.

    Big Yields & Tillage Debate

    The discussion of grain yields and different tillage practices needs to start in producers’ fields. Grain yield comparisons and results from un-biased research are very important for making agronomic decisions that include tillage; however, producers need to put these practices to work in everyday situations across large acres to consider a practice worthy in modern agriculture.

    Application of Nitrogen Fertilizer in Soybeans

    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.

    Cover Crops & Livestock Integration: An opportunity for profit on S.D. farms

    Cover crops have been gaining a reemerging acceptance over the last decade, with very few producers disagreeing about the potential soil health benefits of adding cover crops to their farming operation. However, with low commodity prices producers are trying to reduce expenses on inputs, especially on inputs with a varying or unknown return.

    Soybean Investigations: Research on Your Farm Seeks Farmer Cooperators

    Do you depend on the latest information focused on soybean products? Are you constantly seeking out cost-effective information and looking for what actually works on South Dakota farms? Have you wanted to try a new product but didn’t want to commit to it on your entire field? Have you wondered if a fungicide application is beneficial? Thought about late season nitrogen applications? Do you have soybean cyst nematode and wonder whether or not the seed treatments work? This short list is just a sampling of the many different issues that are occurring in SD soybean fields today.

    Consider SCN Sampling This Spring

    Soybean cyst nematode (SCN) silently robs significant soybean yield without displaying obvious above ground symptoms. Unfortunately, when SCN is introduced in the field, it can never be completely eliminated; however, SCN can be managed to keep SCN population below injury level. By the time one soybean cyst is observed on the soybean roots or in the soil sample, likely more cysts are occurring in that field.
