Chemical farming happened because the bomb makers wanted to continue selling ammonia and giving ammonia to plants does make them grow big. But, it is a shortcut and destroys the symbiotic relationship with the soil life. Initially the soil still had a lot of organic matter and life in it and it only took a small amount of fertilizer. After killing the soil life there is no nitrogen, carbon, or phosphorus cycle, the OM erodes away, and the remaining dirt becomes compacted. As the soil degrades it has taken continually more fertilizer to keep yields up. Pesticides destroy the food chain. They kill pests and their predators which makes it easier for the pests to thrive. Predators keep pest populations in check but do not eliminate them. Fining the use of fertilizers and pesticides would be disastrous. If fertilizers and pesticides are seen as the sole way to grow all of our food the government will absolutely try to step in and pay for a portion or all of the fertilizers and pesticides as prices increase. This is the only way that chemical farming will remain dominant. It is simply becoming too costly to continue chemical farming. Like I said before, the best course is to just let the transition happen at the rate that it happens.
