How it works: 1. Download GrazeOK, 2. With a yard stick, measure forage height and canopy cover (optional), 3. Input your operation details: forage species, livestock, grazing system (continuous, rotational, etc), 4. Get proper stock density, number of pastures, grazing and rest days for your operation.
