Using edge‐of‐field monitoring to characterize water quality: A farmer cooperative case study in northern Missouri

Abstract Edge‐of‐fieldwater quality monitoring was conducted in cooperation with private landowners through the Mississippi River Basin Healthy Watershed Initiative, a landscape conservation program first offered through the USDA‐NRCS in 2010. The study objective was to quantify effectiveness of ind...
