[QUOTE="farmerm, post: 7324096, member: 7195"] Cover crop may put back some N but P and K can not be pulled from fresh air. Sell 4T of wheat and f you don't put anything back you sell about 20kg of potassium mined from your soil, even if your soil start with significant reserves, all mining operations eventually run out of resources. You may be able to make them more available but you will never "regenerate" P and K in soils. [/QUOTE]
