In order to investigate the technological advantages of new composting method by shedding gutter static fermentation, traditional gutter fermentation were compared with new shedding gutter fermentation for investigation in composting shape, temperature, moisture content, pH, contents of nitrogen-phosphorus-potassium and organic carbon in compost.The production cost and benefit was analyzed.Comparing traditional method, results showed that the new shedding gutter static fermentation was more convenient in ventilation for control of temperature.Fermentation temperature increased faster and retained high temperature better, which could kill insects' eggs effectively and no insect pupa flies existed during fermentation process.Moreover, the moisture of compost was removed quickly and the nutrient contents of nitrogen, phosphorus, potassium increased significantly, the production cost reduced evidently.Resultsindicated that shedding gutter static composting for organic fertilizer reduced fermented time, favored for deodorization and corrupting of compost, saved energy for natural drying with solar and biological fermentation heat effectively.The techniques economically benefited with low in investment and running/maintenance cost, was possible to be applied commercially for organic fertilizer production and farm waste disposal.
