Research Project: Water Quality at the Edge of Field and In-stream in the Lower Mississippi River Basin

Location: Delta Water Management Research

Project Number: 6024-13000-004-017-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Aug 31, 2023

Measure, model, and/or estimate the impact of current and innovative farming practices on water quantity and quality while sustaining crop yields and reducing environmental impacts at both the field and watershed scales.

Working at both the field and watershed scale, water samples will be collected and analyzed for sediment and nutrients. At the edge-of-field sites, the samples will be collected with automated samplers triggered when a threshold of flow has passed through the drainage pipe. At the watershed sites, samples will be collected with three methods: weekly by grab sample, every 15-minutes with water quality sondes, and with passive samplers. Practices of interest for this study include cover crops, irrigation innovation, and filter strips.
