• This work was carried out to search for the composting steps which can be met for the regulations from composts manufactured from swine manure and puffing rice hull(6:4) at a large-scale composting plant and changes of composting characteristics based on the material balances. Composting characteristics based on its temperature had maintained high over 60℃ between 15 days and 25 days of composting periods after ten days of the a rapid temperature change. After the 25 days of them, the temperature was rapidly decreasing. The level of nitrogen, potassium, and phosphate during composting periods was 1.25% to 1.87%, 0.62% to 0.85%, and 0.99% to 1.36%, respectively. As with composting process, the nutrients had tendency in increasing. Calcium and Magnesium of the finished products were detected in 3.77% as a calcium oxide and 0.93% as a magnesium oxide, respectively. Manure management for environmental protection provides guidelines that comply with MAF(Ministry of Agriculture & Forestry) regulations concerning animal manures. Guidelines for animal manure composts are the contents of heavy metal and OM, OM : T-N ratio and salt concentration. Our law is regulating that organic matter(OM), OM : T-N ratio and salt contents was more than 25%, less than 50 and 1%, respectively. Cd and As of the heavy metal which regulated by law had never been detected in this trials and some heavy metal and salt concentration detected through composting periods was detected within the regulations. All of the items regulated in the law is to meet them at the 15 days of composting days in this trials. However, Active composting continues to maturation step after 15 days. When applied in the proper amounts at the appropriate times, livestock manures can provide some, if not all, of the nutrients required for many crops. If improperly handled, however, it can be an environmental hazard, resulting in inhibition of crop production, soil productivity and so on. In conclusion, the results of the experiments suggest that resonable controls for the composting of swine manure need in use although composts is to meet the regulation. (rdf:langString) (en)
