AbstractThis note presents a method of calculating how much insulation is required to keep the ground unfrozen all winter if it is covered at the end of the summer with a thick layer of straw (or other insulation). The results indicate that just over 3 feet of straw could be enough to keep the ground surface from freezing if the minimum mean monthly air temperature is -20 degrees F and the ground temperature is 40 degrees F when the straw is spread.
