Southwest ND (07/30/15)

Information from the Southwest region of North Dakota

Most crops in the area are still looking great. After heavy winds on July 27th and 28th lodging could be a concern in areas. Winter wheat and some barley are beginning to be harvested. Sunflowers are close to blooming, scouting for disease and insect problems should continue to catch problems as they arise. Corn is beginning to look thirsty with leaves beginning to roll. Most hay in the area has been baled.

When considering replacing an alfalfa stand remember about autotoxicity. Alfalfa produces a chemical that can reduce the establishment and growth of new alfalfa into an existing stand or alfalfa residue. This effect can last in the soil for a variable amount of time after the stand has been destroyed depending on factors such as soil texture and weather. It may be best to plant an annual forage and wait a year to return to alfalfa if considering replacing a stand.
