How does the Conservation Reserve Program (CRP) try to protect soil for future agriculture?
-The CRP pays farmers not to grow crops on land that is not well suited for crop production.
-The CRP provides grants to farmers willing to use contour farming.
-The CRP created Nation Farmland Reserves, where only pre-industrial farming practices are allowed.
-The CRP imposes financial penalties on farmers who do not employ shelterbelts in areas prone to wind erosion.
