FERTILIZER TRENDS

The 2006 season was marked by a high acreage of soybeans across North Dakota. The results of this on fertilizer use are evident in lower N use than in previous years. High N costs probably affected rates as well as revised N recommendations in minor crops such as flax and dry bean. Sulfur use was down, following trends in canola acreage. Zinc use (not shown) was up, probably due to a higher acreage of corn. The gap between the use of urea and ammonia narrowed yet again, as timing issues, safety, availability and insurance continues to move use towards urea. These data were summarized from the North Dakota Department of Agriculture, Registration Division 2006 fertilizer tonnage report.
