Effective Weed Suppression and Nitrogen Fixation in Cover Crop Mixtures

Example of a successful cover crop mixture demonstrating good weed suppression and nitrogen fixation. Vetch/rye cover crop planted on 8/16/08 and sampled on 5/24/09. Stand height approximately 3-1/2 feet with vetch shoots intertwining with rye stems. Total nitrogen content in the cover crop was 160 lbs nitrogen/acre, with 89 lbs attributed to nitrogen fixation. Seeding rates: rye at 80 lbs/acre, vetch at 50-60 lbs/acre. Megan Gregory, a graduate student in the Drinkwater lab, is shown in the image.

  1. Figure 4. Example of a cover crop mixture with good weed suppression and good nitrogen fixation. Vetch/rye cover crop was planted on 8/16/08 , sampled on 5/24/09. This stand was about 3-1/2 feet tall , with vetch shoots growing up most of the rye stems. Total nitrogen in the cover crop was 160 lbs nitrogen/acre with 89 lbs coming from nitrogen fixation. Seeding rates: rye 80lbs/acre, vetch 50-60lbs/acre. Megan Gregory, shown, is a graduate student in the Drinkwater lab.
