This three-year project will focus on an array of mitigation protocols in a field crop system (corn–soybean–grains). The level of glyphosate herbicide applications will range from “high” (conventional crop practices) to “none” (organic crop practices). The mitigation protocols will involve a spectrum of intercrops or cover crops, as well as a variety of herbicide applications, depending on which protocols are favored by participating growers.
To develop a predictive and quantitative model, in the fall of the second year we will collect soil samples from fields subjected to the four protocols, which represent a range of no-till impacts, and place them in containers destined for a condition-controlled growth chamber. This experimental design with repetitions will allow us to obtain a set of reference values that will supplement the experimental values generated from the 12 fields over three years. We will calculate physicochemical and agronomic indicators, as well as soil glyphosate and aminomethylphosphonic acid levels. Soil microbiome analyses will also be conducted.

The protocols studied in this project aim to reduce the application of glyphosate, a substance classified as "probably carcinogenic" by the International Agency for Research on Cancer.
