Ten ounces of borax or 12 ounces of calcined colemanite should be used for every 10 cubic feet (8 bushels), of manure immediately upon its removal from the barn. Apply the borax with a flour sifter or any fine sieve, particularly around the edges of the pile, for there is where most of Bulletin 118, U. S. Department of Agriculture.
