The crop list in the USGS/PNSP database is reconstructed with the crops listed under column “PEST-CHEMGRIDS” and originally sourced in²⁸. The matched, partial match, and unmatched fractions are calculated and tracked in the quality factor QF_SA described in “Technical Validation”. FOR and NES stand for “forage” and “not elsewhere specified”.
