Compost is organic matter that has been decomposed and recycled as a fertilizer and soil improvement material.
The decomposition process is aided by proper aeration (see photo on the left) by regularly turning the mixture.
Aerobic bacteria manage the chemical process by converting the inputs into heat, carbon dioxide and ammonium.
The ammonium is further converted by bacteria into plant-nourishing nitrites and nitrates through the process of nitrification.
Compost production is followed by refinement to remove any unwanted materials.
