MINNEAPOLIS — Across the world, corn producers and their advisors have been working toward shrinking the exploitable yield gap – the difference between attainable yields and yields under current farmer practices – by increasing their management intensity. In a new study, research evaluated increased management intensity with the goal of ecological intensification and how those practices compared with standard practices.
At research locations in Waseca and Becker, MN, advanced nutrient management paired with intensified agronomic management increased corn grain yield by 22 and 28 percent, respectively, compared to standard practices. The economically optimal combination of practices varied with location and year.

MINNEAPOLIS — The Red River Valley being a place of extremes is nothing new. But in 2021, we set another weather record. This time, we observed the driest January through September on record at the Northwest Research and Outreach Center (NWROC) in Crookston. A common light-hearted question people asked me this summer was, “how’s that […]
LAKE CRYSTAL, Minn. — The September 10 USDA Crop Report increased the projected U.S. average corn and soybean yields for 2021, as compared to the August National Ag Statistics Service (NASS) yield estimates. The latest NASS yield estimates were based on U.S. crop conditions as of September 1st; and were the first 2021 yield USDA […]
LAKE CRYSTAL, Minn. — August is typically the month of the year when we get the first producer survey yield estimates from USDA, as well as yield projections from major private forms. This yield data is gathered in a number of formats from producer surveys to crop tours to satellite technology. There is not necessarily […]
LAKE CRYSTAL, Minn. — The August 12 USDA Crop Report projected an increased 2021 average U.S. corn yield compared to last year and a similar national average soybean yield to 2020; however, it should be noted that both yield levels were reduced from the July USDA estimates. The August yield and production projections were based […]
MINNEAPOLIS — Knowing how to identify common nutrient deficiencies is important for diagnosing issues in the field. Deficiencies can occur on the lower leaves for nutrients considered mobile in the plant while immobile nutrient deficiency symptoms will occur on newer leaves. Deficiency symptoms are characteristic of a particular nutrient and knowing what to look for […]
