Statistical Approach

try to understand the R simulation needed what kind of distribution will I ask R to use? Where will I get a reasonable starting point for the magnitude of that variability. Where will I get guesses for realistic variability so I’m not fixing the game.

Soil Values for Forage Production

USDA One AUM = 915 pounds. Given: Annual forage production = 900 pounds per acre. AUM per acre = (900 pounds per acre) x (25 percent grazing efficiency) = (225 pounds available forage per acre) / (915 pounds per AUM) = 0.25 AUM per acre. Range Science: 1000 lb. Cow with calf consumes - 26 lbs of dry forage per day -760 lbs of dry forage per month 1 Animal Unit Month (AUM) = 760 lbs. of dry forage Calculating Rangeland Production 1. 2.
