ABSTRACT:
To prepare an effective potting media from waste plant products, a mixture of high carbon and high nitrogen organic material is mixed with a phosphoric acid solution to maintain a pH of between 5.5 and 7.1 under aerobic conditions, with or without soil. Ground wheat straw or other high carbon plant materials and ground alfalfa hay or other high nitrogen plant materials are used in the preferred embodiment in ratios of between three parts ground wheat straw or other high carbon plant materials for each seven parts of ground alfalfa hay or other high nitrogen plant materials to seven parts ground wheat straw or other high carbon plant materials for each three parts ground alfalfa hay or other high nitrogen plant materials. The mixture of wheat straw and alfalfa hay has a pH in the range of 7.0 to 8.1. Phosphoric acid 0.04 M is added periodically for approximately one month if the pH of the mixture is higher than desirable for the plant type. The potting media both with and without soil and with and without the addition of fertilizer show unexpectedly good results on plant life which are superior than peat moss or other types of potting media.
