Air is essential for decomposition microorganisms to live and multiphy.

Water provides moisture for decomposer organisms.

In building a compost pile, you are actually building a home for these microorganisms.
Turning and watering the compost heap provides it with air and water that are essential for decomposer microorganisms.

Another ingredient that is often used is soil, which is a source of microorganisms that aids in the decomposition process.

The main decomposer microorganisms are bacteria, fungi, worms and insects.

Kithcen and food scraps can also be incorporated in some methods of composting.

mature compost exudes an earthy smell. is often dark brown or black in colour and feelsm crumbly and sightly moist.

The finer the materials used for composting, the faster it will mature.

Composting for organic farming is the same as discussed above but does not include paper products (tissue paper, paper towels, soiled diapers, cardboard, etc) as these have been treated with chemiclas during the manufacturing process.
