Abstract

Livestock facilities in Korea are on their way of enlargement resulting in increment of livestock manure. When the livestock manure treated inappropriate way during application to the agricultural area, environmental damage can be occurred such as bad smell, water and air pollution. Therefore it is important to make a good management plan for livestock manure treatment. In order to effectively apply organic fertilizer made by livestock manure in terms of quantity and quality, the current status of nutrient in agricultural land should be calculated quantitatively by scientific way. The OECD suggest member countries to calculate the nutrient balance as an agricultural environment indicator which represents the difference between nutrient inputs and outputs of the amount of nutrients in various ways. In this paper, we calculated the nutrient balances according to three cities which have different characteristics such as urban or rural areas. To reduce the nutrient balance, we considered how to reduce the amount of chemical fertilizer by using organic fertilizer made by livestock manure. And public treatment facilities for livestock manure can be a good solution except civil complaints for location selection. Among the options, manure fertilizer application to the agricultural area for cultivation of forage crops was mainly considered to reduce the nutrient balance by decreasing input of chemical fertilizers and increasing output of crop production. Using the field monitoring data, it can be calculated that the daily nitrogen reductions by 116.5 kg/ha and the daily phosphorus increments by 2.7 kg/ha.

2015년 현재 우리나라는 OECD 국가 중 질소기준 양분수지가 1위로 양분관리가 시급한 실정이다. 양분관리를 위해서는 축사에서 발생하는 가축분뇨의 자원화를 통하여 생산된 가축분뇨 퇴·액비를 농경지에 올바르게 살포하여 양분이 순환될 수 있는 구조를 만드는 것이 매우 중요하다. 이는 무기질 및 유기질 비료의 사용량을 줄일 수 있어 농경지에 대한 양분관리와도 연계되어 있다. 본 연구에서는 양분수지를 활용하여 연구대상지역에 대한 양분현황을 파악하였으며, 경제성과 효율성을 고려하여 조사료의 생산을 통한 가축분뇨 퇴·액비의 적절한 활용을 통하여 양분관리 효과를 검토하였다. 지역에서 발생하는 가축분뇨로 생산된 퇴·액비를 지역으로 다시 재순환할 수 있도록 하여, 가축분뇨 액비만으로도 충분한 양의 조사료 생산이 가능함을 보여주었으며, 농경지의 토양에서의 총 질소의 농도저감을 확인할 수 있었다. 질소농도의 감소는 작물의 사용량 뿐 아니라 토양에 축적되거나 지하수 및 지표수로 유출되는 것이 포함되어 수질개선의 효과를 예상할 수 있다.
