양분수지 기반 지역단위 가축분뇨 처리모델

초록

This study was conducted to development of a regional livestock manure treatment model based on nutrient balance. The treatment model converted from compostingoriented livestock manure treatment to wastewater treatment and solid refuse fuel in public treatment facilities due to the excess nutrient balance of arable land. The inputs of 15.2% nitrogen and 22.6% phosphorus decreased, and all could be accommodated through nutrients consumed by crop cultivation. Therefore, applying regional livestock manure treatment models and nutrient management plans that control chemical fertilizers and organic fertilizers, which are the sources of nutrient input, is expected to activate a crop-livestock farming system that considers crop productivity and soil environment.
