Nitrate Dynamics In An Arid Irrgation Network: Can Nutrient Loops Be Closed With Management Techniques?, Kelsey B. Bicknell

Civil Engineering ETDs

Nutrients are the third leading cause of impairment in aquatic ecosystems, yet they remain necessary to support our growing agriculture system. Mining (as with phosphorus) and manufacturing (as with synthetic nitrogen) fertilizers deplete non-renewable resources and consume large amounts of energy. We have opportunities to optimize food-energy-water (FEW) resources, particularly in arid regions where wastewater, rather than agriculture, is the number one contributor of nutrients. This study evaluates the capacity of three unique channels (i.e., the Drain canal, the Delivery canal, and the Rio Grande River) within the agriculture system of the Middle Rio Grande Valley to process nutrients from …
