Cover crops have proven effective in reducing wind and water erosion, improving soil health, and capturing excess N in the fall to prevent leaching. Although the benefits of cover crops to soil health are widely reported, their impact on the yield of the following crops is not clear. The purpose of this North Dakota study was to determine the impact cover crops have on the yield of following corn (Zea Mays L.) and wheat (Triticum aestivum L.) crops along with quantifying nitrogen pools in the soil. Following barley (Hordeum vulgare L.), cover crops were no-till seeded at three eastern North Dakota sites in 2021 and 2022. Prior to frost termination, above-ground cover crop biomass ranged from 660 to 2,600 lb ac-1 across locations. The following spring, corn grain was planted into cover crop and no-cover crop treatments and fertilized with five N rates (0 to 160 lb N ac-1) in a randomized complete block design with a split-plot arrangement. The following year, wheat was planted on these sites and fertilized with the same N rates. After corn and wheat harvest, grain yield was determined and soil samples were taken to a depth of 2 ft and analyzed for NO3-N, NH4-N, and non-exchangeable NH4-N. The cover crop had no significant impact on corn or wheat yield; however, it did appear the cover crop had an impact on the wheat yield response to N. The total known available N (TKAN, sum of preplant soil NO3-N, N credits and fertilizer N) needed to reach maximum yield in the no cover crop treatments was greater than the amount of N needed in the wheat grown two seasons following the cover crop, indicating a potential second-year credit from cover crops may be attainable in these environments.
