We need to use efficient machines to grind gravel into powder, so that the soil life can get to the minerals that are trapped in the rocks When powdered gravel is applied to the soil, a marvelous thing happens. The higher plants then extract the mineral rich juices from those microbes, and pass them down the line to the animals. The worms bore miles of tunnels, which aerate the soil. The plants develop huge root systems, which resist drought. Insects are repelled by the healthy juices of the plants.
Foods become more flavorful and satisfying.
Both yields and quality increase. The plants become more heat and frost resistant. Diseases become rare events. And so on. Too much of a good thing can be very harmful.
