Grids of Agricultural Pesticide Use in the Conterminous United States, 1997

This spatial dataset consists of 219 1-kilometer (km) resolution
grids depicting estimated agricultural use of 219 pesticides in 1997
for the conterminous United States. Each grid cell value in the
national grids of this dataset is the estimated total kilograms (kg) of
a pesticide applied to row crops, small grain crops and fallow land,
pasture and hay crops, and orchard and vineyard crops within the
1- by 1-km area. Nonagricultural uses of pesticides are not included
in this dataset. Of the 219 pesticidesrepresented in the grids, 96
are herbicides, 65 are insecticides, and 37 are fungicides. The
remaining 21 compounds are composed of the category "other pesticides",
which consist of fumigants, growth regulators, and defoliants.
Although this dataset is referenced to 1997, it generally represents
a composite of estimated pesticide use during the mid to late 1990s.
