Four Weed-Management Tips To Do After Harvest

Oct 16, 2014

The harvest has just been completed and even though this season is over, you’ve already started thinking of what needs to be done for next year. Weed management is one of those continuous tasks to think about any time. Richard Zollinger, extension weed scientist at North Dakota State University recommends fourafter-harvest weed-management practices you can do before the winter chill sets in that will give you a head start on next spring’s planting.

Mapping and scouting your fields. When the field is bare, you can see the patches, or hot spots, of weeds that have grown since you removed the crop canopy at harvest. This is a perfect time to scout and map your fields so you know where the problem spots lie come spring.
Herbicide application. Herbicides can be used after harvest to remove any weeds that have appeared after the removal of the crop. This will minimize the number of weeds growing in the spring, making planting easier.
Planting a cover crop. Cover crops can be a very useful tool if you are looking for a non-chemical alternative to manage weeds. Tillage.
Tillage can kill weeds and prevent seed production. Clean fields in the fall and spring will reduce the number of weeds that emerge in the spring, allowing for more effective weed management practices the following year.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
