Expected Nutrient Mineralization from Manure and Crop Residue: Jeff Schoenau

Soil is a magnificent thing. It’s the medium that makes crop production possible. It’s also rather mysterious. Even now, scientists are just beginning to scratch the surface of naming all the microbes that live in soil and understanding their functions and interactions. There’s also much we do know and understand about soil and its ability to provide nutrients to a crop year over year — a process called mineralization — but there are still many questions from farmers on what to expect from crop residues or added manure in the coming year.

In this video, Jeff Schoenau,  professor of soil science with the University of Saskatchewan, explains how different manures impact nitrogen, phosphorus and sulphur availability in the first and subsequent years after application. For the grain farmers in our audience, he also explains how wet or saturated conditions affect N losses in cropping systems, regardless of whether or not you’re using manure.

Yes, you can build your own autonomous tractor

Many situations have two scenarios: one where a problem is looking for a technology, or the other where technology exists and is looking for a problem to solve. In the case of farming, often it's the problem that comes first, but when it comes to autonomy, the technology has been leaps and bounds ahead of…Read more »
