PURPOSE: Mineral compost is provided to increase at least 20-30% income by improving agaric culture medium. CONSTITUTION: A mineral compost for improving agaric culture medium such as rice straw or wasted cotton has several merits: fungus grow well by promoting aerotropic fermentation of compost by dispersing colloid to increase the gap rate; the growth of mushroom is promoted by adding micro-minerals such as sulfate mineral for fungus to take in; mineral compost plays a role of controlling moisture; mineral compost can be spread on even dried straw effectively and with sufficient time because solidification time is 10times longer than usual gypsum, and has cohesive power; toxic damage to fungus by oversupplying potassium or magnesium can be prevented by adding carbonic acid calcium. The mineral compost consists of CaO 45%, S 15%, CuSo4 2%, ZnSO4 1.8%, MnSO4 1.2%, FeSO4 2.5%, MgSO4 2.3%. The mineral compost is made by making carbonic acid calcium react to sulfuric acid of adequate amount to obtain CaSO4-2H2O of 25-30% attached moisture, and calcimning CaSO4-2H2O, FeSO4-7H2O, CuSo4-5H2O, MnSO4-5H2O, and ZnSO4-3H2O to remove attached moisture at 120°C and produce completed Mono Hydrate and Hemi Hydrate at 160-180°C. |
