Plus, this is what I was trained for in college, did travel to several farms to see how they handled their soils and the irrigation methods, some farmers are outstanding because they are well educated even helped install a large irrigation circle that had to be precise, or it would fail within the week of its operation, did wheel irrigation work on a family farm in summer of 1980, had to "buck" the wheel line on occasion to make it go straight across the field.
Crop rotation and soil rebuilding is also employed as they MUST because Hybrid seeds require much more elements for growth that forces them to rotate or there will be increasing difficulties to maintaining soil health and they have learned not to add too much nitrogen at a time which can damage or kill soil microbes this is all 101 stuffs learned in college and seminars I went to.
It was the Rodale group who gave us minimum tilling methods and to plant seed and fertilize in a single pass which help to keep soil tilth up as excessive till destroys soil tilth and porosity over time.
In my own garden beds, I never till or walk on the growing surfaces, add grass clippings several times and then cover the beds with a 2" layer for the winter and I use only open pollinated seeds thus much easier to keep the soils happy.
