Special Issue #8 Released: August 1998
This report is the eighth annual Field Crops Summary issued by NASS containing on-farm agricultural chemical use statistics. The data presented in this report are part of the data series on chemical use funded through the Water Quality Initiative.
The Water Quality Initiative is a multi-agency program designed to provide information for farmers, ranchers, and foresters to address on-farm and off-farm environmental issues. In the past, there has been an inadequate amount of farm level data to determine the magnitude of water quality problems or to permit an assessment of alternatives for farmers and other affected parties. This report and other agricultural chemical reports help fill the needs of analysts evaluating the complex environmental issues of the 1990's.
Nitrogen was applied to 99% of the total 1997 corn acreage in the 10 States surveyed. All of the major producing States included in the survey had 96% or more of their acreage treated with nitrogen. Growers used an average of 1.7 treatments per acre and used an average 76 pounds per treatment. In the States surveyed, 84% of the planted corn acreage received phosphate fertilizer. Potash fertilizer was applied to 72 percent of the acreage.
Herbicides were applied to 96% of the total corn acreage in the survey, while insecticides were used on 30% of the acreage. Atrazine was the most used herbicide with 69% of the reported acreage being treated. Atrazine was applied at the rate of 1.01 pound per acre.
Dicamba and Metolachlor were the next two most widely used herbicides and they were applied to 29% and 35% of the reported acreage, respectively. Chlorpyrifos and Tefluthrin were the most widely used insecticides with 7% of the reported acreage. Chlorpyrifos was applied at the rate of 1.12 pounds per acre and Tefluthrin was applied at .12 pounds per acre.
In Nebraska, nitrogen was applied to 100% of the acreage, phosphates to 80% and potash to 26%. Herbicides were applied to 98% of the corn acreage while insecticide application covered 62%. There were a total of 192 usable reports. At the national level, the 10 states surveyed accounted for 77.0% of the U.S. corn acres planted in 1997.

Nitrogen fertilizer was applied to 84% of the winter wheat harvested acres in the 14 surveyed States; Colorado was the only state treating less than 75% of the grain area. Phosphate fertilizers were applied to 53% of the collective acreage, ranging from just 15% in Oregon to 92% in Ohio. All surveyed States treated at least a portion of the acreage with herbicides; 2,4-D was again the most prevalent in terms of area and total application. The surveyed States represented 35.1 million acres in 1997 and 84% of the U.S. winter wheat acreage.
In Nebraska, nitrogen was applied to 92% of the acreage and phosphates to 74%. Herbicides were applied to 53% of the acreage. There were a total of 81 usable reports.

Soybean producers in the 19 States surveyed applied nitrogen fertilizer to 20% of the area planted to soybeans. The percent of acres treated ranged from 6% in Arkansas to 3% in Michigan. The average number of nitrogen applications per acre was 1.1 with an average application rate of 23 pounds per acre. Phosphate was applied on 28% of the soybean planted acreage in the surveyed States. Nebraska producers applied phosphate to 31% of the soybean acreage, while Minnesota applications covered 20% of the planted acres. Potash was applied to 33% of the planted soybean acreage.
In the 19 States surveyed, an average of 97% of the soybean acreage was treated with herbicides. The most widely used herbicides were Imazethapyr, applied to 38% of the soybean acres, followed by glyphosate and pendimethalin and applied to 28% and 25% of the acreage, respectively. Growers in the surveyed states applied insecticide to only 2% of the total soybean acres planted. With the exception of insecticide applications in Louisiana and N. Carolina, there were too few reports to publish individual state data for insecticides. Growers reported few fungicide or other chemical applications.
In Nebraska, nitrogen was applied to 31% of the soybean acreage, phosphates to 31%, and potash to only 16%. Herbicides were applied to 99% of the soybean acreage while insecticides were not reported as being applied. There were a total of 177 usable reports. At the national level, the 19 states surveyed in 1997 covered 93% of the U.S. soybean acreage planted.
