Earlier quoted context omitted.
What they don't seem to be talking about is learning from indigenous farming communities who use things like diversity in crops and rotation to keep soil quality high. These problems were solved decades ago, just not by the industrial farming community
Crop diversity is great. And you also need lots of organic matter to go on top of the soil: to build life in the soil. that's much better than trying to duct tape the matter with fertilizer.
Crop rotation has been standard practice my entire life. One of the many kickers though is soybeans are the fallback crop for really wet springs. Many crops need to be planted by a certain date or the growing season will be too short. Soybeans can "make up for lost time", so to speak. If your first planting gets flooded, or if it's too wet to get any crop in, you can wait until it's dry and toss in some soy to recoup some of the cost. Thing is soybeans use a lot of nitrogen.

Manure spreaders are still a thing.
