    • Nitrapyrin and Herbicide Concentrations in Soil in the Midwestern US (April 2017 to May 2017)

    Metadata Updated: July 6, 2024

    Nitrapyrin, a nitrification inhibitor, and three co-applied herbicides (acetochlor, atrazine, and metolachlor) were measured in soil samples from an agricultural field in Iowa. Samples were collected from three locations in the field before and after nitrapyrin application in April-May 2017. Soils were collected using a 5-inch pipe that was hammered into the ground. Soil samples were extracted using pressurized solvent extraction (with dichloromethane), clean-up via solid phase extraction (carbon and alumina sorbents), and analyzed by gas chromatography with mass-spectrometry.
