Figuring Stockpile/Hay/Forage Requirements

I originally created this calculator to go along with the leasing pasture series from Meg Grzeskiewicz. Since we've gotten questions from folks on how much winter stockpile they might need, and how much their animals eat, we thought it was a good time to put it center stage on its own. The calculator is really an Xcel spreadsheet.  You plug numbers into the yellow boxes.  The answers you're looking for will show up in the dark green boxes. There are several different part to the calculator, depending on the questions you're asking. The first section (shown below) was designed to help you figure out how much forage you have during the spring/summer grazing season.  The "Total Forage Available" answer it gives you assumes that you'll be leaving at least 50% behind to prevent overgrazing.  If you use this answer as you consider how much winter stockpile you have, note that once the grass is dormant, you can graze shorter because the plant is not actively growing.   The next section of the calculator helps you figure out how much forage your animals eat.  The first thing you'll notice is that it uses a measurement called "AUMs."  This stands for Animal Unit month.  This is a measurement that is more often used in the west where government agencies lease rangeland.  One AUM is the amount of forage required for one cow/calf pair, because that was what was most common on rangelands.  All you have to do is enter the number of animals you have in each cat
