How do I make good Compost in a Compost Bin?
We suggest filling the Compost System by making the heap inside the bin with a mixture of nitrogen-rich material (such as grass clippings, vegetable peelings) and carbon-rich material (such as bark, fibrous material or shredded paper); a good ratio is 1:2. At the base place a layer of twiggy material; ideally build up the heap in 15cm (6″) layers, if possible avoid too much grass clippings or leaves, as air movement is inhibited. Clippings from prunings may be used, although it is advisable to shred woody stems first. Compost only young weeds; weeds with seed, or those about to set seed, should preferably be burned, as should all pernicious and perennial weeds.
A high temperature is produced during the making of compost, this encourages the natural breakdown of organic matter and it also helps to kill weed seeds and some pests and diseases. For a compost heap to heat up sufficiently it should be at least 1 cubic metre (1 cubic yard) in size but preferably the larger the better, although a garden rarely produces this quantity all at once. In two or three weeks the compost reaches its maximum temperature and in about three months it is mature. Turning the heap speeds up the process and ensures complete break down of material. If there is an ammonia odour this indicates that the compost is too rich in nitrogen ; if the heap lacks air there will be a smell of rotten eggs. Invariably there will be some material that will not breakdown fully and this material can be composted again. Use the compost when the rate of breakdown of the organic matter has levelled off ; at this stage, it should be crumbly, dark and sweet smelling.
