Composting Composting is the rotting or breaking down of organic matter into small particles of fertile soil. Composting occurs naturally wherever there is dead organic matter. The process can by sped up by mixing specific ingredients together and putting them in the right conditions. The benefits of finished compost include adding organic matter and nutrients to the soil and increasing the water holding capacity of generally poor sandy soils. Roughly half your household garbage can be composted. Garden waste and
kitchen scraps make excellent compost. Not all organic waste can be easily All organic material is largely made up of different proportions of carbon and nitrogen. To speed up composting a ratio of carbon to nitrogen is required: Approximately 25 to 30 parts by weight of carbon to each part of nitrogen. A rule of thumb is to mix four parts of soft nitrogenous green material such as grass clippings, weeds, fruit and vegetable peelings and wastes with one part of brown material such as sawdust, shredded prunings, newspaper or dry leaves. It is important for the environment that composting is aerobic, which means the matter is aerated. You can do this by tumbling, turning with a spade or using a compost unit with an aerating lung.

Disease-causing bacteria, parasites and weed seeds are normally destroyed at these temperatures. If the temperatures aren't high enough then the weeds and seeds may grow when the compost is put on to the garden.

It is an alternative to hot composting garden waste and fruit and vegetable scraps fromthe kitchen. Worm farms are ideal for people living in flats or houses with small backyards. The worm castings produced are one of nature's best composts and fertilisers. They contain more ready-for-use organic plant nutrients than any composted material or factory made fertiliser. The liquid waste from worm farms is a highly concentrated fertiliser that can be collected, diluted and applied to gardens. The bedding in the worm farm is highly absorbent. Water rarely needs to be added. With the right worm farm you can start with only half of a kilogram of worms and within a few months you will have enough worms to consume most of the household food waste for two people.
Special earthworms, called compost worms, work best in a worm farm, as they thrive in the rich, moist conditions. The most common compost worms are Tiger Worms, Red Wrigglers and Indian Blues. These worms should not be added to compost piles as the conditions are too hot and they will either leave or die. Worm Facts
