SDSU Extension and the South Dakota Soybean Research and Promotion Council are seeking South Dakota Soybean Growers willing to participate in a farmer-led on-farm strip trial research program.

Soybean cyst nematode management starts with a soil test to determine the presence or absence of this nematode in the soil.
The overwintering generation of bean leaf beetle adults emerge in the spring and can cause serious defoliation injury to seedling soybean plants. However, the abundance of overwintering bean leaf beetles is negatively affected when the air temperatures get too cold. Therefore, an estimate of the emerging populations can be made based on how cold the winter was.
Two-year corn-soybean rotation coupled with heavy chemical inputs has become the routine practice of agricultural production in the Midwestern United States. According to USDA/NASS data, corn and soybean prices received by producers in South Dakota both reached the peak levels of $7.39 and $16.00 per bushel, respectively, in August, 2012.
Cover crops are generally defined as crops planted between cash crops to cover and protect the soil. Some demonstrated benefits of cover crops include: reduced soil erosion, increased soil organic matter, increased biological diversity, increased nitrogen supply, and weed control. Depending on the farmers’ objectives, different species of cover crops can be planted. For example, if a farmer’s main objective is to increase nitrogen supply, then legume cover crops best suited to the farm area should be selected.
Many emotions set in on farmers that hear the word “non-GMO”, but it could help them in times like today when prices are low for many farm products in South Dakota.
Is your yield monitor indicating low yielding areas in your soybean field? Soybean Cyst Nematode (SCN) could be the problem. Get to the root of the problem by testing your soil for the soybean cyst nematode. SCN management starts with a soil test to determine the presence or absence of this nematode in the soil. Absence may indicate either the SCN has not established in the field or could be present in non-detectable levels.
Late-season soybean diseases can sometimes be mistaken for natural senescence. A closer look at the stems and roots of dying plants and the pattern displayed by dead plants in the field may reveal root or stem rots going on. In order to devise effective management practices for future soybean seasons, it is important to determine the cause of early soybean plants death.
When gearing up for soybean aphid scouting, it is important to think about the population densities that warrant insecticide management.
Soybean cyst nematode (SCN) is the main soybean production constraint in South Dakota. Soybean plants can be infested with SCN but may not display visible symptoms.
