Abstract
We investigated the possibility of utilizing spent mushroom culture-medium as raw material to produce organic compost. Mushroom culture-medium contained 2.69% nitrogen, 41.07% carbon, and 0.99% phosphoric acid. Nitrogen and carbon content in rice bran were 3.08% and 47.34%, respectively. Nitrogen, carbon, and phosphoric acid content in mushroom Pleurotus eryngii were 3.41%, 34.63%, and 1.70%, respectively. Our study aimed to evaluate the degree of decay of compost produced from the substrate, used to culture King Oyster mushrooms by analyzing seed germination indexes in cucumber, radish, lettuce, and Chinese cabbage. Our results showed that compost from spent mushroom culture-medium completed the stabilization process in 4 to 6 weeks, as evaluated by the appropriate organic compost maturity point for the plantation.
