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...

Temperatures fell into the low 30’s and upper 20’s in most of Iowa over the weekend of October 11-13.  Because of the very late planting season, some crops were immature enough to be injured by the freezing temperatures. This ICM Blog will address frost damage concerns to soybeans.

Staging crops is an underappreciated but incredibly important skill. One very important reason to know how to stage your crops is because herbicide products may have limits on what growth stages of the crop they can be applied.
