After the drought this past year, some pastures may benefit from a renovation in 2021. Proper planning and preparation are needed to successfully improve pastures with either a late winter frost seeding or no-till renovation with interseeding next spring. This ICM Blog post will discuss what you...

This week is a welcome break from the fall chill, and it is a great opportunity to finish up any final fall weed management in pastures and no-till crop fields. Ideally, herbicide applications should be made when the sun is shining and daytime temperatures are above 50-55 degrees Fahrenheit....

When it comes to applying fall anhydrous ammonia or manure with a high ammonium N content (like liquid swine manure), we recommend that soil temperatures at a 4-inch depth are below 50° F and continue to trend cooler to help minimize nitrogen loss prior to the next growing season. While soil...

A concern for corn fields damaged by this year's Derecho is how best to manage volunteer corn in 2021. Our recommendation is to rotate to soybean or some other crop if at all possible since additional control options are available in soybean (...

August's derecho left many Iowans with unharvestable corn. For operations that left their corn in the field, decisions should be made to reduce the problem of volunteer corn next planting season.

Downed corn from the August 10 Derecho, which affected millions of acres in Iowa, will contribute to significant volunteer corn populations in crop fields in 2021. Volunteer corn ranging from 800 to 13,000 plants per acre can cause yield losses up to 54% in soybean and up to 13% in corn,...

Following the derecho event on August 10, millions of acres in Iowa face challenging conditions. In many cases the corn may be unharvestable. These unharvestable fields require some level of fall management to ensure the future crop can achieve even emergence and normal early plant growth.

Weeds, Herbicide Resistance

One important benefit of cover crops to our production system is providing an alternative selection pressure on weed populations. Cereal rye has the best potential to suppress weeds because it accumulates more biomass than other cover crop species.  Weed suppression is closely related to the...
