Detailed Description
A team of scientists studied changes in nitrapyrin — a nitrification inhibitor applied with fertilizers as a bactericide to kill natural soil bacteria for the purpose of increasing crop yields — occurrence associated with land use changes from March to June 2016. The above photographs document the following conditions: recent anhydrous ammonia application (upper left), corn planting (upper right), early emergence (lower left), and early corn growth (lower right). The corn field was upstream from the sampling site at West Branch Wapsinonoc Creek, Iowa (USGS Site ID: 0546494170).
