Forage & Grazing Calculators
Work out how many pairs a pasture will carry, how long a paddock lasts, and where your AUMs actually go.
Stocking decisions get made on standing forage, not on gut feel. These calculators run the same dry-matter and animal-unit math an extension agent would work through on a legal pad — forage production, utilization rate, animal unit equivalents, and days of grazing left in the paddock.
7 calculators in Forage & Grazing
