southern MN | There are so many variables.
One thing that shows up if the ground hasn’t been plowed in a long time, plowing it releases a bunch of stored fertility in a short time. If this is what’s happening, it is a one time deal, not near as much effect in following years.
Or, heavy wet cold soils can be improved by getting air and warmth to them, if a northern climate. Now that we are trying to plant corn with frost in the ground still, anything that helps the ground warm up, and get the microbes active, will help bump up the crop.
But on southern soils, or even light dry soils in the north, it would be quite different.
Depends so much on so many things. Just 2 thoughts.
