Claim:
A horticulture growing medium, comprising: a vermiculite component, wherein the horticulture growing medium includes 1% to 50% by volume of the vermiculite component; a perlite component, wherein the horticulture growing medium includes 1% to 50% by volume of the perlite component; a soluble sulfur component of 100 to 800 ppm; and an anaerobically digested manure with a humic acid component of 0.4 to 6% by weight, wherein the horticulture growing medium includes 10% to 75% by volume of the anaerobically digested manure, and the vermiculite component, the perlite component, and the anaerobically digested manure provides a submixture that has an initial pH and has a sufficient buffering capacity such that if 200 grams of aluminum sulfate were to be added to a 2.5 cubic-foot sample of the submixture, the initial pH of the 2.5 cubic-foot sample would decrease less than 2.8 pH units.
