southern MN | In my mind I would think soil temperature and soil moisture would have a lot to do with it, and that varies a lot year to year, making it very hard to predict an easy number that would repeat every year?
You might be a little too dry some falls to do much mineralization, I might be way too saturated some summers to have much soil activity going on?
Is my thinking logical enough on this, or am I out in left field?
