본 연구는 돈 분뇨 액비에 미생물 첨가가 배추의 발아지수에 미치는 효과를 구명하기 위해서 수행하였다. 돈 분뇨 액비는 107일 동안 폭기와 무폭기 상태로 액상비료를 제조하여 공시하였고 미생물 첨가는 $0.05\%,\;0.1\%,\;0.2\%,\;0.3\%$ 수준으로 하였다. $0.05\%$ 미생물 접종 처리구에서 식물 독성이 낮고 발아지수가 높게 나타났다. 첨가수준별 돈분 액비 이용시험에서 초기 돈 슬러리의 액비성상은 T-N 2,873 ppm, T-P 753 ppm, $NH_4-N$ 1,441.6 ppm, $NO_3-N$ 16.48ppm으로 50일이 되면서 폭기조건에서 T-N 3,672 ppm, T-P 164 ppm, $NH_4-N$ 183.87 ppm, $NO_3-N$ 21.97 ppm로 변화하였으며, 무폭기 조건에서 T-N 1,261 ppm, T-P 68 ppm, $NH_4-N$ 161 ppm, $NO_3-N$ 16.87 ppm로 나타났다. 미생물을 처리하지 않고 107일동안 폭기조건과 무폭기 조건으로 액비화한 시료의 발아지수는 각각 83과 40.4이였다. 돈 분뇨 액비를 무산소 제조시 $40\%$ 이상, 호기제조시 $50\%$ 이상의 발아지수가 개선되었다. 이와 같은 결과는 액비제조 처리가 무산소 제조보다는 호기제조 처리가 작물에 양호한 것으로 판단되어지며 이는 호기처리시 총질소의 함량을 높게 유지할 수 있도록 하는 결과인 것으로 사료된다. This study was carried out to investigate the effect of Synechocystis sp. KACC 91007 when added to a pig slurry or pig liquid fertilizer (PLF) on germination index (GI) of Chinese cabbage. The preliminary experiment involved the screening of inoculant levels which were; 0.05, 0.1, 0.2, and $0.3\%$, respectively. The $0.05\%$ level of inoculant was selected based on low phytotoxicity and high GI.. The PLF underwent a 107 day aerobic and anoxic processing conditions. The T-N, T-P, $NH_4$, and $NO_3-N$ concentrations of the untreated pig slurry were; 2,873, 753, 1,441.6, and 16.48 ppm, respectively. Using aerobic processing treatment, the fertilizer value of the PLF was 3,672, 164, 183.87, and 21.97 ppm, respectively. In contrast, the fertilizer value of the PLF processed under anoxic condition was reduced to 1,261, 68, 161, and 16.87 ppm. The GI value of the untreated PLF under aerobic and anoxic processing condition was 83 and $40.4^{*}\%$, respectively. With the addition of the $0.05\%$ microbial inoculant, the GI improved by more than 40 and $50\%$ respectively, when the PLF was processed under anoxic and aerobic conditions. The above findings proved that the aerobic processing of PLF for 107 days was better than anoxic and yielded higher T-N which is a macro-nutrient fertilizer material. Consequently, the addition of $0.05\%$ microbial inoculant resulted to a higher GI of the Chinese cabbage specifically under aerobic processing condition.

This study was conducted to determine the odor reduction efficiency of a biofilter desist using different filter materials. The summary of results are as follows; 1. The airflow penetration rate of the different filter materials namely; rice straw, woodchips, rice hulls and sawdust were 0.72 m/s, 0.64 m/s, 0.48 m/s and 0.17 m/s, respectively. 2. The elimination of $NH_3$ gas was fastest in the rice hull at a rate of 4 mg/${\iota}$ followed by sawdust, woodchips and rice straw at 3 mg/${\iota}$, 3 mg/${\iota}$ and 7 mg/${\iota}$, respectively. 3. The filter material made of wood chips was able to eliminate the offensive gas known as $H_2S$ at a rate of 2.2 mg/${\iota}$ on the 7th day, 17.6 mg/${\iota}$ on the 21st day but decreased to 10.7 mg/${\iota}$ on the 36th day. In contrast, the filter material composed of sawdust had a continuous increase in the reduction of $H_2S$ at a rate of 12.3 mg/${\iota}$ on the 7th day, 18.3 mg/${\iota}$ on the 21st day and 20.1 mg/${\iota}$ on the 36th day. The above findings indicated that among the filter materials, sawdust was the most effective in absorbing $H_2S$. Airflow penetration rate can be related to $H_2S$ odor elimination efficiency as shown by the slowest airflow rate of sawdust which is only 0.17 m/s.
