Many people still renovate their pastures with plows.
Others burn or use fertilizer to rejuvenate grassland. Some grass farmers are trying new equipment that aerates forages, stimulating growth and tillering. Other ranchers time their grazing to ensure growth and long-term sustainability of their pastures.
