Practical Soil Science Research with Brady Goettl

In this episode we revisit Agronomy on Ice for another great conversation this time with NDSU extension soil health research technician Brady Goettl. If you’ve benefited at all from extension soil health work in recent years, you’ve probably been the beneficiary of Brady’s work in some form or another. Brady discusses his research, what led him into the soil science field, his extension work which includes direct interactions with farmers regarding soil health, and his quest to better understand soil fertility and nitrogen management.

“In order to get a full picture of what's happening when you plant that cover crop, you have to do a really intensive sampling and through a ton of different avenues. So what I'm doing with my research is more of a traditional approach where we're looking at nitrate, ammonium and non-exchangeable ammonium in the soil.” Brady Goettl

Brady hopes to “develop some sort of either nitrogen credit or recommendation” for producers based on the cover crop biomass produced. The research is ongoing but could lead to less input needs based on “credits” attributed to different practices after determining how they all interact with each other.

“We know that there's a lot of these microbes that can fix nitrogen and do it symbiotically. So we don't necessarily need a legume, for example, to fix that nitrogen… If we can harness the power of those guys to help us fix nitrogen, that's gonna be a game changer if we don't have to rely on synthetic nitrogen anymore.” - Brady Goettl
