Manure Composting
Plants need nitrogen to build up their tissues which is absorbed by the roots of the plants. So, it is imperative that the soil contains a rich content of nitrogen. If the soil is not rich enough, it has to be replenished and supplemented by some other external sources like compost.
Manure is a rich source of organic materials and is available in a variety of animals such as chicken, pig, sheep, duck, goat and cow. So, while composting, it is better to layer the manure with dried leaves and not just simply add into the pile. This will be effectively decomposed and incorporated into the compost.
Manure should be removed regularly to prevent surface water contamination and help the parasite control and fly breeding since flies breed in moist manure. Manure has to be removed everyday and stockpiled for later use. Manure should be spread and thinly distributed to break up larger manure piles.
Aeration speeds up the composting process of manure and the more often it is turned, the faster it would compost. Perforated PVC pipes can be inserted into the pile to provide aeration, though it is a little labor oriented. There should be enough moist in the compost manure and the manure has to be sweet smelling. If unpleasant odor comes, then the compost is wet and should be kept under a cover to keep the moisture out.
Composting manure is a great supplement for the soil and should be spread only on cropland or other ungrazed, vegetated areas.
