Service GRAS-21: Calculate Grazing System, AoA, and Grazing Period Forage Animal Balance (gras_grazsysfab)
Calculate weighted average monthly and daily forage production for each AoA. From each monthly production, divide by the number of days in the month to get daily production.
Calculate forage supplies for each area of analysis (AoA) in the grazing system, accounting for forage partition profiles (FPPs).
Calculate a forage animal balance for a period as one or more herds are assigned to graze available forage on a grazing unit in the grazing system.
