So wrong about how much nitrogen is in the soil. They’re only measuring inorganic or available N. Organic or “unavailable” N is always more than enough needed to grow a good crop even without fertilizer. If we do things to increase the microbial population in our soil, they will turn the unavailable N into a plant available form when the plant needs it. We have to do away with the soil chemistry tests we so often use.

Remember yields have nothing to with profits.
