Cover crops
Plan the right cover for the gap, and see what it gives back.
Don't leave the field naked
Bare soil is bleeding soil — rain hits it, wind lifts it, carbon leaves it. A cover crop keeps the ground clothed between cash crops, and pays rent in roots.
The planner
gap what window you have goal erosion, N, or biomass? pick matched to your zone + gap payback what it returns to the next crop
Why it matters
The cheapest fertility program on earth is a root in the ground every month of the year.
