Strategic Farming: Field Notes

In this episode, Brad Carlson, water resources extension educator, and Dan Kaiser, extension nutrient specialist, discussed nutrient availability in corn, especially nitrogen based on previous crops, use of urea, and other nutrients, such as sulfur. Joe Ikley, Extension Weed Specialist at North Dakota State University also discussed weed and herbicide interactions in the recent hot weather we’ve been having. Drought-stressed weeds have a tendency to produce more protective cuticle, so additional carrier or surfactant is often needed to get herbicide active ingredient penetration into the plant. Anthony Hanson gave updates on insect issues occurring in mid-June, such as true armyworm and alfalfa weevil.
