This study was carried out to determine the effect of swine liquid manure on the rice growth and yield in 2006. Field experiment was conducted under variable application rates; 100%, 120%, 150%, 180% N level of slurry based on 11 kg N 10a recommended amount of nitrogen. The experimental sites were located at Cheorwon in Gangwondo area. The results were summerized as follows; In the plot treated with swine liquid manure of 150% and 180% N levels, the plant height and tillers were higher, and the color of leaf was darker than that of 100% N level of swine liquid manure. Rice yield in the plot applied with 120% N slurry level was increased at 11%, but those of 150%, 180% N-level application plots were reduced 10, 19% compared to 100% N level, respectively. Rice quality of the 100 and 120% application plots of swine liquid manure was significantly better than those of 150 and 180% levels of application plots. Total nitrogen content in rice plant after harvesting was increased with increasing levels of swine liquid manure. The content of K in the soil was accumulated in plot treated with 150%, 180% slurry compared to control plot. The heavy metal contents in soils were not increased treated with swine liquid manure. The density of bacteria was low in the application plot of 180%N of liquid swine manure. The bacteria/fungi ratio was highest in 120% N level of liquid manure treatment.

우리 농민들의 생존권을 위해 한.미 FTA 협상 반대에 대한 목소리가 높아지고, 2012년부터 해양배출이 금지되어 가축분뇨 처리문제에 비상이 걸리는 등 우리 양돈산업의 생존을 위한 대책 마련이 발등의 불로 다가온 가운데 양돈인 스스로의 양돈산업 경쟁력 향상과 액비를 통한 가축분뇨 자원화로 분뇨처리 문제 해결을 통해 위기를 극복하는 지부가 있다. 강대천 지부장을 중심으로 가축분뇨 자원화에 앞장서는 전남 영암지부(지부장 강대천)가 그 주인공들이다.

This study was conducted to analyze growth characteristics and adaptability of poplar clones under the treatment of liquid pig manure. The average of survival rate was 33% better at control than the treatment under age of 5 years. But, tree height and DBH growth were higher at the treatment than control. Populus euramericana 'Eco28' showed the highest survival rate (97.9%) under the treatment. P. euramericana 'Eco28' and P. deltoides hybrid 'Dorskamp' could be selected as superior clones for height and DBH growth under the liquid pig manure treatment. The above-ground biomass production was also investigated when the poplar clones were 5 years old. The aboveground biomass under the liquid pig manure treatment was, on average. 52.6 ton/ha, which was 80% higher than control (29.1 ton/ha). P. euramericana 'Eco28' (73.6 ton/ha) and P. deltoides hybrid 'Dorskamp' (71.1 ton/ha) showed superior biomass production than other clones at the treatment of liquid pig manure. Based on survival, growth and demage traits, the adaptability of poplar clones to liquid pig manure treatment was estimated. P. deltoides hybrid 'Dorskamp' and P. euramericana 'Eco28' showed better adaptability to the treatment. P. nigra ${\times}$ P. maximowiczii '62-10' and P. koreana ${\times}$ P. nigra var. italic 'Suwon' were identified as poor adaptability clones.

This study was conducted to evaluate the effect of swine liquid manure (SLM) on rice grown in Yeonggwang-gun in 2008. The treatments consisted of SLM and chemical fertilizer (CF) based on the recommended amount of nitrogen (11 kg N $10a^{-1}$). The Total N content of the SLM used was 2,881 mg $L^{-1}$. Plant height at the early stage of growth and tiller number were not significantly different between plots applied with swine liquid manure and those with chemical fertilizer in all areas. Plant height at the later stage of growth, lodging and yield were not significantly different between plots applied with swine liquid manure and those with chemical fertilizer in three areas (Baeksu, Gunnam, Beopseong). Plant height at the later stage of growth, as well as lodging were higher in SLM plots than in chemically fertilized plots in Yeonggwang and Yeomsan. However, grain yield was lower in SLM plots than in chemically fertilized plots in these areas. Soil organic matter content and exchangeable cations increased in the swine liquid manure applied plots. Moreover, heavy metal content did not increase in the plots treated with swine liquid manure. Further research to determine the suitable rate of swine liquid manure is needed to reduce lodging damage and to increase the yield and quality of rice.

본 시험은 1997년 9월부터 1998년 10월까지 제주 화산회토양의 혼파초지에서 양돈 분뇨시용에 따른 목초생산 및 유해성분 축적에 미치는 효과를 규명키 위해 질소시비 수준과 양돈분뇨의 시비수준을 달리하여 분활구 배치법으로 시험이 수행되었다. 목초초장이나 건물수량은 질소시비수준 1, 150 및 300kg/ha에 따라서 통계적으로 유의적 차이를 얻었으나 양돈분뇨시용 1, 750, 1,500 및 3,000kg/ha 효과는 얻지 못했다.(중략)

양돈인들의 가장 큰 고민거리를 이야기한다면 빠지지 않는 대표적인 문제인 분뇨처리. 양돈인 누구에게나 해당하는 걱정거리이다. 2012년부터 해양투기가 금지되는 상황을 감안하면 더욱 그렇다. 하지만 배만용 지부장(만종축산 대표)은 "분뇨 처리 걱정을 왜 하느냐"고 반문한다. 경북 경주지부(배만용 지부장, 59세)는 양돈인들의 숙원사업인 가축분뇨처리 문제해결을 위해 2002년부터 액비사업을 활발히 추진하고 있으며, 이제 그 축적된 노하우를 타 지역 축산농가 및 지방자치단체에 알리는데 선도적인 역할을 담당하고 있는 경북 경주지부를 찾아가 보았다.

This study was conducted to estimate aboveground biomass and nitrogen storage potential of tree species-eight clones of a poplar and hybrids, one clone of Salix alba L., dawn redwood (Metasequoia glyptostroboides Hu and W.C. Cheng), yellow poplar (Liriodendron tulipifera L.), Okamoto maple (Acer okamotoanum Nakai), and pin oak (Quercus palustris $M{\ddot{u}}nchh.$)- after treating with liquid pig manure. Stems showed the highest percentage of aboveground biomass, and followed by branches and leaves. Nitrogen content in aboveground biomass components was the highest in leaves, and followed by branches and stems. Average aboveground biomass production was higher in the clones and species treated with manure than those of not treated, 30 ton/ha and 16 ton/ha, respectively. In the manure-treated site, clone 'Dorskamp' of Populus deltoides${\times}$Populus nigra showed the highest aboveground biomass (48.3 ton/ha). Average nitrogen storage potential was superior in the clones and species treated with manure than those of not treated, 159 kg/ha and 90 kg/ha, respectively. Clone 'Dorskamp' also showed the greatest nitrogen storage potential (286.5 kg/ha) among tested tree species. Therefore, 'Dorskamp' is the most suitable clone for treating liquid pig manure, but additional studies are needed to determine any damages or tolerance from the treatment.
