Tweety there is nothing to learn because there is nothing to teach. There is no way to replace removal rates of Sulphur, Phosphorus, Potassium, Boron, Zinc, Iron, Chloride, Magnesium, Manganese and Copper on a grain cropping farm without adding them as fertilizer of some sort. Especially since sulphur dioxide emissions regulations have been working their magic.
We are in the soil mining business, consumers need food nutrients and those nutrients ultimately come from our soils via the crops we sell. Eventually those soil nutrients have to be replaced, it is just a matter of when.
Until urban sewage plants devise a way to scrub and concentrate these flushed nutrients so they can be placed back on the land they came from, we have a broken system. No amount of wishful thinking about organic matter and healthy soil will fix it, that is just a short term band-aid. The piper will have to be paid, eventually.
