“…일반적으로 혐기소화액의 경우 난분해성 유기 물 함량과 염류조성이 여타 부산물과 차이가 있기 때문에 혐기소화액비의 EC 값은 토양 환원 시 시용량 결정 및 부 숙도 평가에 있어 중요한 요인이 될 수 있다. 그러므로 안 정적인 농지 환원을 위해서는 EC를 중심으로 한 살포 프로그램이 필요하다(Hong et al, 2012). 또한 염분이 많은…”

Bio-gas production offers the dual benefit of livestock manure treatment and energy extraction. However, anaerobic digestate containing residual nutrients like nitrogen and phosphorus lacks defined legal standards posing potential environmental risks if improperly managed. Understanding its physical and chemical characteristics is crucial to prevent soil, water, and air pollution.This study assessed the quality of anaerobic digestates and liquid fertilizers from domestic biogas facilities. Anaerobic digestate had average values of pH 8.21, EC 48.68 mS/cm, NaCl 0.28%, moisture 96.99%, CODCr 20,973 mg/L, SCODCr 8,016 mg/L, T-N 0.53%, P 2 O 5 0.13%, K 2 O 0.30%, and total NPK content of 0.95%. NH 4 -N was 3911 mg/L, NO 3 -N 228 mg/L. Trace elements As, Cd, and Hg were below detection limits; Pb 0.49 mg/kg, Cr 0.89 mg/kg, Cu 13.90 mg/kg, Ni 0.47 mg/kg, Zn 58.21 mg/kg, CaO 1,219.41 mg/kg, MgO 429.11 mg/kg, B 2 O 3 56.76 mg/kg, MnO 11.18 mg/kg, Fe 255.41 mg/kg, Mo 8.56 mg/kg. Liquid fertilizer by anaerobic digestate had pH 8.69, EC 29.74 mS/cm, NaCl 0.23%, moisture 97.46%, COD Cr 14,022 mg/L, SCOD Cr 5,710 mg/L, T-N 0.30%, P 2 O 5 0.08%, K 2 O 0.27%, total NPK content 0.65%. NH 4 -N was 1923 mg/L, NO 3 -N 334 mg/L. Trace elements As, Cd, Hg, and Cr were below detection limits; Pb 0.23 mg/kg, Cr 0.76 mg/kg, Cu 9.79 mg/kg, Ni 0.41 mg/kg, Zn 51.78 mg/kg, CaO 693.73 mg/kg, MgO 268.18 mg/kg, B 2 O 3 50.56 mg/kg, MnO 6.63 mg/kg, Fe 190.70 mg/kg, Mo 7.30 mg/kg.Maturity assessment using mechanical disruption indicated "immature or semi-mature" status for most samples. The germination index yielded a value of "0" for all samples.

A more efficient use of nutrients from organic sources can benefit both farmers and water quality in agriculture.In this paper we reviewed information related to the regulations and guidelines of a swine liquid fertilizer to propose an establishment scheme for the official standards of swine manure slurry as a liquid fertilizer for organic farming. According to the law of establishment and designation of official standard of fertilizers, the liquid fertilizer made with pig liquid manure belongs to the byproduct fertilizer as of one of organic fertilizer. However, the official standards for byproduct fertilizers including the liquid fertilizer set by the Rural Development Administration (RDA), especially for a liquid swine manure fertilizer, should be revised to meet the goals of laws pursuing the environmentally sound agriculture, especially for organic farming because the terms and relevant standards need additional specific standards alike the standards such as impurities and parameter for declaration in EU. Therefore, it is suggested that official standards for byproduct fertilizers should be revised with respect to nutrient, salt content as of SAR and Na content instead of NaCl. Also we need to develop the maximum limit of heavy metals in soil to which the liquid fertilizer can be applied, as well as application rate depending on EC of the liquid fertilizer.
