A landowner wants to implement regenerative agriculture practices and is considering two new cover cropping systems (A and B) for her farmland. She expects the cover crops to produce considerable soil health benefits. The initial costs and annual net benefits are below. Neither is expected to have a salvage value at the end of a 4-year useful life.
