Summary

This data set represents the Nematicide use on agricultural land in kilograms per square kilometer, 2009 value compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network (i.e., watersheds). This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data were produced by Naomi Nakagaki (USGS, written communication, 2013). Units for the Nematicide use on agricultural land in kilograms per square kilometer, 2009 are kilogram per square kilometer. Reach catchment information characterizes data at the local scale. Reach catchments [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the Nematicide use on agricultural land in kilograms per square kilometer, 2009 for NHDPlusv2 reach catchments and upstream river networks and in order to support statistical analysis, map display, and model parameterization.
