Table 1. Nitrogen input values for source and land-use type for counties in the study area, south-central Idaho.

[Nitrogen input values from 1998 data. Nitrogen input by dairy cattle and precipitation were not estimated by county, but by their own spatial distributions. Dairy cattle input varies widely due to animal population densities. Inputs range from 0 to 232 pounds per acre per year (lb/acre)/yr). Precipitation inputs range from 1 to 6 (lb/acre)/yr, with most of the area receiving 2 (lb/acre)/yr.
