Managing Water with Soil Health
Wednesday Oct 13, 2021
Wednesday Oct 13, 2021
In this week’s episode of Streamlines, John McMaine and Anthony Bly continue their soil health and drainage discussion by covering the following topics:
- Can we see a win-win-win situation when looking at habitat, agronomy, and water quality in a system?
- If we are seeing so many benefits to drainage and soil health systems, why isn’t everybody doing it?
- What appears to be the biggest barrier stopping producers from adopting soil health practices and how can we overcome that barrier?
- Identifying functional Biology versus Chemistry in soil systems.
- The original system conversation and what we have to look forward to for future technologies and practices.
Dr. Eileen Kladivko is once again the special guest speaker, a professor in the agronomy department from Purdue University. Additional resources related to Dr. Kladivko’s research can be found at https://ag.purdue.edu/agry/drainage/Pages/New-Summaries.aspx.
