FERTILIZER TONNAGE UPDATE

The following is a summary of fertilizer tonnage data taken from the North Dakota Department of Ag tonnage reports from 1995 through 2003. The most remarkable trend is the source of nitrogen fertilizer through this nine-year period. In 1995, more than twice as much N was applied as anhydrous ammonia as urea. In 2002 and 2003, this gap narrowed to almost 50/50. The data for urea is for urea sold as urea. However, blends are also recorded in by ND Dept. of Ag, some of which contain urea.

So although the numbers for N from anhydrous ammonia look larger than N from urea, there are probably about 15,000 tons of N as urea incorporated into blends not reported as urea. Phosphates and potash numbers have been flat during this period, and sulfur numbers have increased, then decreased with the rise and fall of canola acres. People have remarked how much more 28% liquids we probably use now compared with past years, but the numbers suggests that tonnage is still relatively low at about 2% of total N use.
