This report summarizes pesticide application and cropping data collected in 1971 from 1,473 agricultural sampling sites in 37 states as part of the National Soils Monitoring Program. Pesticide application data are summarized by all sites, state, and crop. Tables generally give the number of reporting sites, the number of times a compound was applied, the percent occurrence, and the arithmetic mean total application rate. Pesticides applied most frequently to sampling sites were atrazine, 2,4-D, captan, and malathion. Pesticides were most frequently applied to field corn and cotton, least frequently to alfalfa/bur clover and mixed hay.
