Compost Based on Mineral Fertiliser

摘要

The compost includes living and dead microorganisms together with a mineral substrate (such as rock phosphate) partly digested during a relatively dry, self-heated composting process. A fish hydrolysate nutrient and first inoculum including thermophiles is mixed with ground rock, which has been made lighter and more porous by addition of sawdust. The composting process is aerobic as a result of air blown through the composting mass. A second inoculum is mesophilic and persists until application. The dry product has a neutral pH.
