  • This study was carried out to determine the effect of continuous application of animal liquid slurry on the growth and yield of rice in 2005. Field experiment was conducted under variable continuous application years of animal liquid slurry; 1, 3, 5 application years of slurry and chemical fertilizer as control plot. The effects of different application years of slurry on the growth characteristics and yield of rice were determined. The plant height and tiller's number of 1 year application of liquid slurry were lower than those of the chemical fertilizer plot. But in the plot of 5 years continuous application of animal slurry, the height and tillers of rice were higher than those of 1 year application. And the color of leaf 5 years application years plot was darker than that of the chemical fertilizer. Yield of the 5 years continuous application of slurry was 4% higher than that chemical fertilizer, but that of 1 year application was decreased 6% compared with chemical fertilizer. The long time application of animal slurry was increased content of organic matter, $P_2O_5$ and exchangeable caution(K) in soil.

  • This study was conducted to investigate the bacterial capability to accumulate phosphorus during liquid composting process of pig slurry. Storage liquid compost and pig slurry were analyzed by using MALDI-TOF technique, which showed the colonies of Acinetobacter towneri and Bacillus licheniformis. In addition, bacterial colonies were isolated under high phosphoric acid conditions using X-phosphate MOPS medium with the addition of 2 mM $K_2HPO_4$. Microbial growth was observed in high and low phosphoric conditions due to the growth of bacterial diversities in the liquid fertilizer and slurry. The colonies isolated in the high phosphoric acid medium were uncultured bacterium clone and Acinetobacter sp. were identified by analysis of 16S rRNA gene sequences. Uncultured bacterium showed higher growth rate and excellent phosphorus ability then Acinetobacter sp.. In addition to Paenibacillus sp. AEY-1 isolated from pig slurry performed excellent phosphorus utilizing capability.

  • Aerobic treatment of animal slurries represents an increasingly popular option for farmers in the management of animal wastes. This study was performed to find out the chemical characteristics of dairy slurry associated with liquid-solid separation. Total solids concentration varies widely depending on the slurry manure handling systems. Hydrogen ion exponent(pH), volatile solids(VS), ammonia nitrogen(NH$_3$-N), nitrate nitrogen (NO$_3$-N), and chemical oxygen demand(COD) essentially depends on the total solids content of animal liquid wastes. Total solids content of the dairy slurry ranges from 6.6 to 7.5% depending on the feed slurry and separator. Separated liquids from dairy slurry have been successfully downed for up to about 21, 900mg/$\ell$ of the COD value. It has also been found that separated slurry decreased from 37.8 to 26.0mg/$\ell$ of the NO$_3$-N concentration.

  • Two types of reactors were set to investigate the change of characteristics of pig slurry by aeration during fertilization period. One system was equipped with air diffuser to supply oxygen to pig slurry for liquid fertilization, but there was no air diffuser in the other system. Air supply to the experimental systems was regulated by air flow meter. The reactors were set up in the laboratory to protect the pig slurry from external condition such as temperature and humidity changes. Maintaining optimal pH range in the experimental reactors is an important factor for liquid fertilization of pig slurry. In this study, pH ranges of aerobic reactor and anoxic reactor was 7.04~7.19 and 7.34~7.81, respectively. The temperature of aerobic reactors was $2{\sim}3^{\circ}C$ higher then indoor temperature. The amount of sludge accumulated at the bottom layer of non-aerated reactors was 4~5 times more than that of aerated reactors.

  • Pig slurry, urine and fermented liquid manure were evaluated measuring electrical conductivity (EC), dry matter (DM) contents and other components. Samples were collected during a period from February to April, 2001: slurry samples from 70 storage tanks, urine samples from 19 and 20 fermented liquid manure samples from 109 pig farms in Jeju. Samples were analyzed for pH, EC, DM, $NH_4$-N, K, P, Ca, Mg, Na, BOD, S-S, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn and OM. Relationships between EC or DM and various mineral and $NH_4$-N contents were examined using linear regression. EC, DM, all mineral contents and $NH_4$-N were higher in slurry samples than in urine or fermented liquid manure. EC, $NH_4$-N, Ca, Mg and Na concentration was similar in urine and fermented liquid manure, but K and DM values in liquid manure were twice as much as in urine. P concentration was higher in urine than in liquid manure. $NH_4$-N and Na in slurry, $NH_4$-N in urine and $NH_4$-N, P and Ca in fermented liquid manure were highly correlated with EC, while $NH_4$-N, P, Ca and Mg in slurry, $NH_4$-N and Ca in urine, and K, P, Ca, Mg, and Na in fermented liquid manure with DM (P<0.05). BOO in slurry (22,520 mg/mL) was higher than that in urine (4,763) and fermented liquid manure (2,701). Results indicated that slurry is a better fertilizer source than urine or fermented liquid manure. However, slurry may pollute soil more than urine or fermented liquid manure when applied to land, although the levels are not above the permit.

  • This study was conducted to investigate the effects on chemical properties of soil and yield of chinese cabbage when the piggery liquid slurry (ADS) digested anaerobically in the biogas plant was sprinkled to the soils. Treatments were composed of non-nitrogen plot (PK), chemical fertilizer plot (NPK) and ADS plot, and were arranged by randomized block design with 3 replications. The ADS was an alkali (pH 8.6) fertilizer containing 0.55% of total nitrogen, optimal levels of phosphorus, potassium and other components. When based (100%) on the yield of chinese cabbage in the NPK, those of the ADS and the PK were 114% and 43%, respectively. The nitrogen absorption of chinese cabbage at 50-d after transplant was significantly greater (p<0.05) in the ADS than other treatment. Heavy metal contents of soil were not difference between before and after experiment. With supplementing phosphorus and potassium sources in it, the ADS should be an excellent fertilizer in cabbage culture.

  • Until now, The experiment about the forage crop have been almost not conducted on the reclaimed land. Therefore, this experiment was carried out in order to know productivity of summer forage crop using slurry composting-biofilteration (SCB) liquid fertilizer on reclaimed land of Hwaong and Sukmoon in korea from 2008 to 2009. The forage crops used in this experiment were corn and sorghum${\times}$sorghum hybrid which are used as summer forage crops in South Korea. The experiment was treated with chemical fertilizer (CF), swine slurry (SS) and SCB liquid fertilizer. Dry matter (DM) yield of corn was higher than those of sorghum${\times}$sorghum hybrid in both reclaimed lands but the effect of SCB liquid fertilizer was not appeared. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of corn were lower than those of sorghum${\times}$sorghum hybrid. The crude protein (CP) content and in vitro dry matter digestibility (IVDMD) of corn were higher than those of sorghum${\times}$sorghum hybrid. In generally feed values of corn were higher than those of sorghum${\times}$sorghum hybrid. The results of this study showed that summer forage crop cultivation using uses SCB liquid fertilizer on reclaimed land are possible.

  • Regarding the dangers to soil, water and air, which come from current agricultural application measures for nitrogen, a sectoral approach for a non-polluting liquid manure utilization cannot be used any longer. Slurry was not any longer considered as a tiresome waste produced of animal husbandry, but as a valuable fertilizer. The goal of the largest possible utilization of slurry on the farm was and still is in the foreground, An Integrated system approach has to be found. leading to a drastic improvement of nutrient utilization and hence to a considerably reduced nutrient use. This can only be expected, if the organic manure can be applicated at times, when losses through leaching and volatilization can be minimized. The necessary investments for such concepts can clearly be reduced through cooperation.
