A Study on the Animal Waste Management in Northern Chungbuk Province and its Strategy

충북 북부지역의 가축분뇨처리실태와 개선대책

A study was conducted to develop a management policy of animal waste in Northern Chungbuk province through investigating the status of animal waste management. In management of swine manure, rotary composting including a simple piling method has a portion of $64\%$ using as a liquefied fertilizer $18\%$, purification $9\%$ and ocean dumping $9\%$ respectively. Most of them use the animal waste as a fertilizer to the agricultural land. The exercise ground of dairy farms was bedded with $70\%$ of sawdust and $30\%$ of conventional soil ground besides the stall. They had a storage tank for the waste water from milking parlor. Korean beef cattle farms mostly run sawdust stall, which changed new one in a term of 6$\~$12 months. In case of layer, manure management was conducted in the order of simple piling method, rotary composting and ventilation into the piling mostly. Comparing the amount of excreted animal manure with that of possible spreading, the latter can be spread more than 2.9 times than the former in Northern Chungbuk province. The Northern Chungbuk province is an appropriate place to carry out an environmentally friendly animal production. An utilization model as a liquefied fertilizer should be developed for paddy field, upland field, orchard, and forage field to in-crease the value of animal waste effectively.
