rotational grazing

From the FarmPlate glossary:

Rotational grazing refers to the practice of moving livestock herds into new pastures to allow old fields to recover and regrow. Crops are often planted between grazing cycles since the animal waste deposited by grazing livestock produces richer, more fertile soil. Pasturing or grazing can save farmers the costs associated with buying grain feed for their livestock, and rotational grazing is one way to ensure a reliable supply of healthy grass for consumption by cattle, hogs, chicken or other pastured animals.
