Composting is the making of fertilizer using vegetable and plant refuse and relying on the natural process of decay. It is mostly carried out on a small scale but recent methods have been developed to accomodate a larger scale of composting. The Open Permaculture School and Regenerative Leadership Institute suggests a lot of advantages of composting including, but not limited to;
Composting is a fairly cheap process that relies on the principles of re-using and re-cycling. All you really need to make a compost is plant and vegetable waste and a place to heap it while it decays. The whole entire process is natural and as such is very cheap to institute and maintain. Expenses such as in cost, transport and manufacture are usually not necessary making it quite a cheap process of making fertilizer.
Composting is reliant on waste. As such you get to play an eco friendly role in preserving the planet by avoiding the dumping of such waste. When dumped, this kind of waste products release a lot of methane gas while decaying. This gas is toxic to the environment, and that can be reduced in a compost heap or bin by gradually turning the compost. Research also shows that compost manure helps increase the fertility of soil that has been previously exposed to chemical fertilizers.
