Composting is speeded up by watering, turning and the action of worms.It usually take a year to turn compost into good soil but there are products on the market that can get this down to about 10 weeks.
It depends upon the type of compostable materials, and upon the meeting of certain compost pile requirements. For example, the best compostable materials are kitchen scraps other than dairy, greasey and oily, and meat products; and yard wastes such as grass clippings. For such compostable materials fit easily into the brown, carbon-rich and the green, nitrogen-rich categories. Additionally, certain levels of air, moisture, and temperature must be met. For decomposition without adequate air becomes anaerobic. Such a breakdown in the absence of oxygen produces methane, which is a greenhouse gas. Also, the pile mustn't be waterlogged. Instead, it must have the consistency of a gently wrung out sponge. And the pile must be turned regularly. The more the pile is turned, the faster does composting turn compostable materials into compost. In fact, under the previously described conditions, it's possible to have compost in anywhere from less to a month to less than a year.
Compost, once fully decomposed as it should be, keeps forever.
It is basically a rich top soil at that stage.
All the organic matter has already been transformed into humus, which is a stable compound, so you don't lose any more carbon.
Some nitrogen might escape as ammonia over time, especially if the compost heap gets dry, or from leaking if overwatered.
Adding some soil or cellulose to your compost while still maturing will help fix the nitrogen.
Other nutrients will still be present though, so you can "revive" an old compost adding chicken manure or another fertilizer rich in nitrogen if the content is low.
Four to eight (4 to 8) months is the length of time that it takes to compost manure anaerobically. The method in question restricts air flow to low levels through the use of pits or trenches. It takes longer because its practitioners do not need to monitor heat, light, and moisture levels in the way that aerobic composters do or to turn the layers.
composting usually takes 3-6 weeks to decompose.
its takes a jed year to decompose and a jed year means nothing
Cardboard, egg shells, fruit peels, grass clippings, leaves and paper are six things that decay and that may be put in compost piles. Fruit peels and grass clippings decompose within six months while cardboard and leaves -- excepting beech and oak -- require 12 to 24 months. Egg shells take at least three years to decompose.
