“Nitrous Oxide Emissions from Saturated Riparian Buffers: Are We Trading a Water Quality Problem for an Air Quality Problem?” with Dr. Morgan Davis and Dr. Tyler Groh.
Riparian buffers are areas of perennial vegetation planted around stream banks and other riparian zones to protect against soil erosion and nutrient leaching. However, tile drainage systems—piping laid under fields to keep them from becoming too saturated—are designed to bypass riparian buffers, leading to potentially harmful levels of nutrient leaching. Saturated Riparian Buffers are a relatively new conservation technique that aims to reduce those water quality issues by redirecting excess water back into the soil. However, their installation could potentially lead to increased levels of incomplete denitrification, resulting in excess nitrous oxide, a potent greenhouse gas, being released into the atmosphere. Drs. Morgan Davis and Tyler Groh work together to examine saturated buffer design and these potential environmental tradeoffs.
This episode, listen in to find answers to the following questions:
- What is tile drainage, and how is it installed?
- How does denitrification work, and why is it a necessary process?
- In what ways can we attempt to improve saturated riparian buffer design?
- Is there really a tradeoff in air and water quality when installing saturated riparian buffers?
