Applying N fertilizer to some fields in the fall instead of the spring offers several benefits to com producers and fertilizer suppliers. Benefits for producers often include paying less for fertilizer, reducing the amount of field work that must be accomplished in the spring, and avoiding soil compaction associated with application of fertilizer on wet soils in the spring. Benefits for suppliers include more time for movement of fertilizer materials from the manufacturers to the producers and more acres per year covered by each fertilizer applicator.
