Turkish agricultural soils are insufficient with regard to organic matter content. Likewise, organic matter amounts in agricultural areas of Bolu are low. The benefits of organic matter to physical, chemical and biologic properties of soils are known for very long time. On the other hand, huge amount of chicken excretions are produced in Turkey with increased chicken production recently, and this result in substantial health and environmental problems. Amount of chicken excretions are estimated about 10 000 000 tons in Turkey. In Bolu, these amounts of chicken excretions are 300 000 tons per year. The most appropriate way to solve this question is to transform chicken excretions to organic manure and apply to agricultural fields. Composting is basic process for transforming of chicken excretions to organic manure. Composting is the aerobic decomposition of organic materials in the thermophilic temperature range of 40-65 °C. There are two essential methods in composting. One of them is traditional method taking much time and producing low grade manure. Another is rapid composting method taking less time and producing high grade manure under more controlled conditions. Rapid composting methods which are more acceptable as commercially in the world are windrow, rectangular agitated beds and rotating drum, respectively Selection of appropriate method is depending on composting material, environmental and economical conditions. Chicken excretions occurring large amounts in Bolu must be transformed to organic manure by means of a suitable composting method and used in agriculture. Because, chicken manure is an important resource for sustainable agriculture in Turkey and it should be evaluated.
