Unharvested sugarbeets in your fields this spring? Here are some nutrient management considerations

By: Dan Kaiser, Extension nutrient management specialist I have received a few questions this spring regarding nutrient management considerations for fields with unharvested sugarbeets. The main question is whether the sugarbeets left in the field could provide a potential nitrogen (N) credit for this year’s crop. The issue this spring seems to be directed towards the northwest Minnesota growing region, and the answer on what to do is a bit more complicated with more crops potentially being grown in 2024. However, here are a few key takeaways. Can you take a nitrogen credit? While many would consider there to be some potential for additional N availability, there is no credit given to the unharvested portion of the beet. Beet tops alone might provide an N credit to next year’s (2025’s) crops depending on how green the beets were when the tops were removed. However, the decomposing root can actually tie up nitrogen for the 2024 crop, so adjustments may need to be made where N rates are

This new, innovative program is a hybrid, year-long, statewide course designed for those who work with farmers including crop advisors, consultants, educators, agency personnel, agronomists, ag lenders, and personnel at non-profits, Soil and Water Conservation Districts (SWCD) and Natural Resources Conservation Service (NRCS) offices. This unique opportunity will take a deep dive into cover crops and will be tailored to Minnesota cropping systems and conditions. We will address the challenges and opportunities associated with using cover crops in Minnesota and attendees will be able to participate in research trials members develop to help address some of the unknowns around cover crops. The academy will kick off with in-

Soybean fertilizer management: IDC, sulfur, P and K soil tests, and more

In this episode of the Nutrient Management Podcast, we’re talking about soybean fertilizer management. What should farmers who are growing soybeans this year be thinking about, including IDC concerns from last year? What does new research tell us about soybean and sulfur? Are there other nutrients or practices that you do or don't suggest for soybean based on current research? What tips do you have for Minnesota soybean growers looking to increase yield? TRANSCRIPT Guests: Daniel Kaiser, Extension nutrient management specialist (St. Paul) Jeff Vetsch, U of M researcher (Waseca) Seth Naeve, Extension soybean agronomist (St. Paul) Additional resources: Managing iron deficiency chlorosis in soybean Is it worth applying sulfur to your soybean crop?

Risk management for early planted soybean

 Anibal Cerrudo, Researcher, and Seth Naeve, Extension soybean agronomist Key points Photo: Dave Nicolai Early soybean planting can lead to higher yields : Early planting offers advantages in resource utilization, potentially resulting in increased yields compared to delayed planting. Consideration of frost dates and plant-to-emergence stage is essential : When planning early planting, it's crucial to assess the local risk of late frosts after emergence, germination chilling injuries, and the duration of the plant-to-emergence stage to determine optimal planting windows. Seed quality and protection are imperative : Ensuring seed vigor and employing technologies like fungicides and insecticides are essential for early plantings to enhance crop resilience against environmental challenges. Utilize available data and technologies : weather records, leveraging local monitoring, weather forecasts, and seed technologies can aid farmers in making informed decisions to reduce risks while s

Is it worth applying sulfur to your soybean crop?

By: Dan Kaiser, Extension nutrient management specialist One question I have been receiving lately has been, what is the value of sulfur for soybean? Sulfur is an essential nutrient needed by all crops. Research has shown that sulfur can increase the yield of soybean in Minnesota but the larger responses that we have seen in Minnesota occurred before sulfur was being consistently applied to row crops in the state. Sulfur carryover While the crop-available form of sulfur (sulfate) is leachable in the soils, the movement of sulfate is not rapid, and some sulfate can be carried over from one year to the next. One example is a study funded by AFREC where sulfur was applied at 25 pounds per acre as ammonium sulfate (AMS) ahead of the corn crop over a period of six years. Corn was grown in years 1, 3, and 5 while the impacts of carryover sulfate were measured on soybean in years 2, 4, and 6. During the first application of sulfur, there was little crop response to the applied sulfur, but ove

MN CropCast: An in-depth discussion about successful corn and soybean planting in 2024

In episode #32 Dave Nicolai and Seth Naeve chat with Dr. Jeff Coulter, University of Minnesota Extension corn agronomist about planting the 2024 corn crop in Minnesota. In addition, Seth, U of MN Extension soybean specialist, discusses the outlook for soybean planting this spring. Jeff talks about optimal corn planting dates, desired soil conditions, corn planting populations and corn maturity hybrid planting dates. Seth also discusses in detail the results of early soybean planting date research and recommendations for soybean planting populations. While recent snow/rain events in Minnesota decreased the level of moderate drought (D1) ratings in Minnesota to 43% as of March 28th compared to 75% the previous week, Minnesota is still in the category of “Abnormally dry”. However, both agronomists indicate that April precipitation can still have a significant effect on increasing soil moisture, thus corn and soybean planting should proceed in a traditional timetable based on soil conditio
