nd-crops NEWS RELEASE Ag Chemical Usage May 19, 2005 North Dakota Fertilizer and Chemical Usage North Dakota farm operators applied nitrogen to 98 percent of the other spring wheat acres in 2004, according to USDA's North Dakota Agricultural Statistics Service. Phosphate was applied to 86 percent of the other spring wheat acres and potash to 27 percent. Comparison data for other spring wheat fertilizer usage came from 2002. During 2002, nitrogen was applied to 97 percent of other spring wheat acreage, phosphate 83 percent and potash 19 percent. During 2004, nitrogen was applied to 95 percent of the durum wheat acres. Phosphate was applied to 70 percent, while potash applications covered 6 percent. The most recent comparison data for durum wheat was from 2002. During 2002, nitrogen was applied to 88 percent of the durum wheat acreage, phosphate 58 percent and potash 5 percent. Nitrogen was applied to 64 percent of the soybean planted acreage in 2004. Phosphate was applied to 63 percent and potash to 11 percent. The most recent comparison data for soybeans was from 2002. That year, nitrogen was applied to 64 percent of soybean acreage, phosphate 59 percent and potash 11 percent. MCPA was the most commonly applied herbicide in other spring wheat in 2004, with 60 percent of the acreage covered. Other herbicides used for other spring wheat include Fenoxaprop, Bromoxynil octanoate and Bromoxynil applied to 49 percent, 25 percent and 20 percent of the acreage, respectively. During 2002, MPCA was applied to 62 percent of other spring wheat, Fenoxaprop 42 percent, Bromoxynil 30 percent and 2,4-D 26 percent. The most popular herbicide applied to durum wheat in North Dakota during 2004 was Fenoxaprop, used on 55 percent of the acreage. Other commonly used herbicides for durum wheat include MPCA, Glyphosate and 2,4-D applied to 50 percent, 45 percent and 39 percent of the acreage, respectively. In 2002, 2,4-D was applied to 55 percent of durum wheat acreage and MPCA to 36 percent. In soybeans, Glyphosphate was the most commonly applied herbicide, covering 88 percent of the 2004 acreage. Other herbicides used were Imazamox and Imazethapyr at 5 percent each. In 2002, Glyphosphate was applied to 50 percent of soybeans, Sethoxydim 25 percent and Bentazon 24 percent. The agricultural chemical use estimates in this report refer to on-farm use of commercial fertilizers and pesticides on targeted crops for the 2004 crop year. The farmers operating the sampled fields were personally interviewed late in the growing season or after the farm operator had indicated that planned fertilizing and pesticide applications were completed.
