> As for non-mineral things like nitrogen, isn't the soil supposed to have an ecosystem that replenishes these things? Iowa farmers grow corn for money, and Soybeans to replenish the nitrogen. They have discovered enough uses for the "waste" soybeans that sometimes it is worth more than corn, but the original reason soybeans were planted was for the cheap nitrogen. |
