Summary

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.

Purpose

The purpose of the data collection was to document the persistence of nitrapyrin in soil after application. This data set can be used to direct future transport, toxicity, and ecological studies focused on nitrapyrin.
