Nebraska-Led Survey Seeks Your Input on Precision and Emerging Weed Control Technologies

Debalin Sarangi, Extension Weed Scientist, University of Minnesota, Ankit Yadav, Weed Science Graduate Student, University of Nebraska–Lincoln, Amit Jhala, Extension Weed Management Specialist, University of Nebraska–Lincoln Weed management is at a crossroads. Herbicide resistance is limiting chemical weed control options, while emerging technologies such as camera-guided “see-and-spray” sprayers, laser weeders, electric weeders, and autonomous machines, are creating new opportunities for weed control. Scientists at the University of Nebraska–Lincoln are conducting a survey to learn about your perceptions of these technologies. We invite farmers, crop consultants, and other agricultural professionals from Minnesota and beyond to complete a short, anonymous survey about your weed management practices, your views on emerging weed control technologies, and the research priorities you would like to see addressed. Why your response matters Your input will help guide future weed science rese...

Crop and livestock integration Virtual Farmer Shop Talks: 3 November dates to learn from your farmer peers

Photo: University of Minnesota Extension Crop and livestock integration is an intriguing idea, but it might feel challenging to make it work on your own operation. Join us for Virtual Farmer Shop Talks, where you can meet up with other farmers interested in crop and livestock integration.  Each session will start with a farmer pitching their question to the group; the rest of the session is what you make of it. Share your experience with others, ask your own questions, or sit back and learn from your farmer peers.  Whether someone has 2 or 20 years of experience with integration, they have valuable knowledge to share and insightful questions to ask the group.  Register here These Virtual Farmer Shop Talks are free to attend, and once you register you'll have access to all three Shop Talk sessions: November 9, 2026 How can you maximize your row crop ground and pasture to extend the grazing season? Pitched by Amber Britz 12 - 1 p.m. CST November 12, 2026 How do you make ann...

Fall manure outlook: Updated application rates and best practices

Photo credit: Nancy Bohl Bormann, University of Minnesota Extension It's early / mid October in Minnesota, which means it's time for the fall manure outlook on the Nutrient Management Podcast. Minnesota's manure application rate guidelines have been updated for corn-corn and corn-soybean rotations. What are some of the results of these changes? What was the reason to update the guidelines? What weather conditions might we experience with the predicted 2026 Super El-Nino? Knowing these, are there changes that farmers should make to their fall best practices? ManureDB (the online manure nutrient database) recently had a large data set added to it. What does the new data mean for the end user? Are micronutrients included in ManureDB's data? In the world of on-farm research what’s currently happening - and how can farmers get involved? Important upcoming events for manure technicians, and farmer questions round out today's episode of the Nutrient Management Podcast . ...

Prepare Your Alfalfa Field for Winter

Beatriz Bizzuti , Assistant Professor and Forage Extension Agronomist As summer comes to an end and temperatures cool,  it is time to start preparing the stand for winter. How an alfalfa field enters winter can have a major influence on its ability to survive cold temperatures and produce forage the following spring. Fall management is especially important in the Upper Midwest, where alfalfa can be exposed to freezing temperatures, ice formation, snow cover, saturated soils, and rapid temperature changes. The goal of fall management is not simply to produce one more harvest. It is to balance the value of late-season forage with the need to allow plants to build reserves and develop adequate winter hardiness.   Why does fall management matter? Alfalfa stores carbohydrates and other reserves in its crown and roots. These reserves help the plant survive winter and support regrowth in the spring. As plants approach dormancy, they gradually allocate resources to their crown a...

Managing Weather Extremes, Biologicals, and Soybean Planting and Harvest Timing with OSU’s Dr. Laura Lindsey

In Episode #73 of MN CropCast, hosts David Nicolai and Seth Naeve sit down with Dr. Laura Lindsey, Extension Soybean and Small Grains Specialist at The Ohio State University. Dr. Lindsey shares critical agronomic insights from her career—ranging from baseline Soybean Cyst Nematode (SCN) sampling to evaluating biological seed treatments and the yield impacts of harvest timing under extreme weather conditions. Plus, get an exclusive look into her flagship research and extension project, "Battle for the Belt," which pits corn and soybean planting dates head-to-head across Ohio field locations. Catch Dr. Lindsey in person as a featured speaker at the upcoming Minnesota Crop Pest Management (CPM) Short Course in Minneapolis on December 9th! Discussion Topics: Baseline Soil & SCN Survey: Early in her OSU career, Dr. Lindsey conducted a statewide survey collecting 299 soil samples across Ohio. The study revealed that 60%–80% of sampled fields contained Soybean Cyst Nematode (SCN...

Manure rate recommendation update: What's new and important considerations

By: Melissa Wilson, Extension Specialist for Manure Nutrient Management We recently updated the University of Minnesota Extension  manure application rate recommendations for non-irrigated corn based on recent soil fertility research.  Like with fertilizer, manure application recommendations are based on nitrogen rate research trials conducted across Minnesota over the past two decades (over 230 rate trials have been completed, most in the past seven years!).  Our goal is to evaluate the agronomics of corn production while minimizing the risk of N losses from overapplication. However, fertilizer-only application rates also take into consideration a third aspect – the economics of corn production (nitrogen cost versus corn prices). This is the Maximum Return to Nitrogen (MRTN) method. Since the economics of manure application are quite different and incredibly variable across farms, the MRTN method is not applicable when using manure for the growing season it is...

Sorting out myths about lady beetles: What’s in a name?

Claire LaCanne, Anthony Hanson, and Eric Yu, Regional Extension Educators In early fall during soybean harvest, especially on a warm sunny day, the exterior walls of your house might be crawling with a few different types of unwelcome insects looking for shelter before winter. One of the most common of these is the multicolored Asian lady beetle, which is not native to North America (Fig 1.). This insect will find its way into homes, especially older homes that have small gaps and openings, and overwinter there until spring to avoid cold temperatures . They also feed heavily on a range of insect pests. Figure 1. Multicolored Asian lady beetle cluster together to survive winter in sheltered areas like trees, leaf litter, or buildings. Photo: UMN Extension. However, there are several myths about these multicolored Asian lady beetles, or so-called “Asian beetles” or “lady beetles” which earn them more disdain than they deserve. We’ve been noticing some misunderstandings and disgruntlement...
