본 시험은 가축분 시용조건에서 수수 × 수단그라스 교잡종중 우리나라에서 많이 재배하고 있는 장려품종 4종(988, Jumbo, TE-Haygrazer, NC+ 855)을 공시하여 생육 특성과 생산량 및 사료가치를 구명하였다. 가축분은 톱밥 발효분으로 ha당 우분 40톤, 돈분 및 계분은 30톤을 파종 보름전 시용하였으며, 파종은 ha당 30kg의 종자를 휴폭 50cm로 1995년 4월 21일에 실시하였다. 수수 × 수단그라스 교잡종의 초장은 우분, 돈분, 계분의 가축분 종류와 품종에 관계없이 평균 219~234cm의 범위로 비슷하였으며, 출수 시작일을 기준할 때 NC+ 855가 7월 1일로 가장 빨랐으며, 다음이 TE-Haygrazer였고(7월 4일), 988은 늦었으며 (7월 12일), Jumbo는 계속하여 영양생장중에 있었다. 연간 건물수량은 우분 시 시용조건에서 11.27~13.92톤/ha, 돈분시용시 11.46~12.77톤, 계분시용시 9.70~13.52톤 이었으며, 품종별 평균수량은 988이 11.31톤, Jumbo 11.26톤, TE-Haygrazer 11.77톤, NC+ 855 13.40톤으로, NC+ 855에서 수량은 다소 높은 경향이나 품종별 유의적인 수량차이는 인정되지 않았다. 1차와 2차 수확시 조사한 조단백질, 조지방, 조섬유, NFE, 조회분 등 사료가치는 품종별 차이가 작았으며, 조단백질 생산량은 품종별 유의적인 차이없이 988이 1,526, Jumbo 1,429, TE-Haygrazer 1,502, NC+855 1,659 kg/ha이었다. 결론적으로 가축분 시용조건에서 자란 수수 × 수단그라스 장려품종 4종간 조 만 생육 특성은 인정되었으나 사초의 수량이나 사료가치는 유의적인 차이가 없었다.

The amount of nutrients entering the soil annually about 100 million tonnes. Among the 100 million tons of nutrients is chemical fertilizers 600,000 tons with manure compost/liquid fertilizer 400,000tons. Fifty percent of nutrients is sprayed to soil but the crop is not used. So building up nutrients in the soil is released into the water together. There is no system that can maintain nutrient balance of the country. Chemical fertilizers and manure compost manure is used on an ongoing basis. Rivers, oceans, lakes, and reservoirs become serious problems of eutrophication. Nitrogen and phosphorus is the cause of eutrophication. As the excessive accumulation of water discharged to the environment, resulting in algae and red tides. The government responded by introducing the amount of total nutrient system in 2008. So the amount of nutrient that can be sprayed on the soil was picked reduced. For the reason, the farmers is became the handling of manure seriously. Since 2012, the manure is that speculation was banned in the ocean. Processing method and system response measures on land was needed. In this study were investigated for reuse and to remove the ammonium nitrogen contained less than 80 % of the total nitrogen with the Air stripping technique.

This study aimed to evaluate the effects of probiotics as manure additives on pathogen, mineral, carbon dioxide and methane emissions in pig slurry as a function of time and provide information about the importance of pig slurry management to pig producers. An experiment was a completely randomized design and four treatments: CON: no treatment (5 kg pig slurry), T1: 5 kg pig slurry + 0.2% bacillus subtilis, T2: 5 kg pig slurry + 0.2% yeast, T3: 5 kg pig slurry + 0.2% actinomycetales. All treatments were replicated three times. The results information that is analyzed includes the following: First, in spite of the lack of statistically significant differences, pH values and carbon dioxide were lowered (P < 0.05) in all probiotic treatments compared with the controls as a function of time. Second, all probiotic treatments had no effect on Salmonella enterica, mineral, and methane emission. The results of this study indicated that addition of 0.2% probiotic to pig slurry resulted in lower pH and carbon dioxide emissions, and carbon dioxide and methane emitted from pig slurry is not listed as noxious gases.
