METHODS OF MANUFACTURING FERTILIZER, AND RESULTING FERTILIZER THEREOF

摘要

One existing method of manufacturing fertilizer from organic wastes involved collecting the egestion from earthworms and simply allowing the egestion to ferment. However, it was found that the resulting fertilizers are not satisfactory. New and improved methods are herein disclosed, in which additional filtering and/or aerating steps are involved. It was found that the fertilizers from the new methods have much improved phosphorous and nitrogen contents than those from the existing method.
