Several brassica cover crops have recently gained popularity in the U.S. Midwest as nitrogen scavengers that are believed to reduce N losses and increase the amount of residual N available to the next cash crop. Field studies were conducted at three sites in Minnesota to determine the effect of fall‐planted brassica cover crops on (i) N availability to the subsequent year's crop of oat or corn, (ii) oat and corn grain yield, and (iii) corn yield response to applied N fertilizer.
