  • The study was carried out to evaluate odor emission during storage time and quality of liquid slurry fertilizer along with three storage container types installed at farmer's fields in Cheorwon. Liquid slurry manure stored in the liquid-circulated or the air-injected tank was very homogeneous in concentration of nutritional elements because of well mixing operation, while nutritional concentration of the manure stored in the non-treated tank was significantly different from top to bottom in the tank, which may bring about partially irregular growth of plant after its application. The potential capacity of offensive odor emitted from liquid slurry manure stored in the liquid-circulated or the air-injected tank was much lower than that emitted from manure stored in the non-treated tank. Low potential capacity may less emit offensive odor after application of piggery liquid slurry on the field. The efficiency in oder to reduce odor emission from liquid manure was slightly higher in the liquid-circulated tank than the air-injected tank

  • Fifteen clones of poplars, 2 clones of willows, and yellow poplar were used to evaluate the effects of 5 treatments such as SCBLF (slurry composting and biofiltration liquid fertilizer), general slurry liquid fertilizer, chemical fertilizer, groundwater, and control (no treatment) on vitality, growth performance, and biomass production. Five cuttings for each tree species were planted in 3 replications. After planting cuttings, a coppice was induced by cutting off stems at 10cm above the ground. Data were collected for first growing season and trees were harvested at the end of October. Maximum mortality rate i.e. 96% was recorded in the cuttings treated with groundwater and minimum 92% with control (no treatment). In all tree species, sprouting of stump was not differ significantly among the treatments. Total nitrogen concentrations of leaves and stump sprouts were higher in the treatment of SCBLF than the control, 26.6% and 22.9%, respectively. Biomass production was highest in the stumps treated with chemical fertilizer, $1.98Mg\;ha^{-1}\;year^{-1}$, and lowest in control ($1.34Mg\;ha^{-1}\;year^{-1}$).

  • Pig slurry has been considered as environmental waste to be treated in an appropriate manner. Recently, there has been the movement toward reusing the pig slurry as an alternative fertilizer sources for agricultural lands. For instance, SCB(Slurry Composting & Biofiltration) liquid fertilizer has been developed and widely used in Korea. However, the impacts of swine slurry liquid fertilizers on both agricultural environment and crop yield have not been investigated yet. Therefore, the current study was conducted to accumulate the basic data which can be subsequently used to determine appropriate application amount of swine slurry liquid fertilizers (SCB liquid fertilizer and storage liquid fertilizer) as well as the application method for each liquid fertilizer. For this, growth of rice was cultivated under the treatment of SCB liquid fertilizer, storage liquid fertilizer, and chemical fertilizer. Also, control treatment (no fertilizer) was included for comparison and all treatments were conducted in five replication. Rice growth was good with the treatment in the order of chemical fertilizer>storage liquid fertilizer>SCB liquid fertilizer>control and likewise, the yield amount of rice straw was in the same order of rice growth. The rice yield amount appeared to be no difference among the treatment except control which showed the least yield amount. Also there was no difference in nitrogen and phosphorus concentrations in rice among the treatment except control which showed the least concentration.

  • A wide diversity of liquid fertilizers and composts produced from the livestock manure in Korea is commonly applied to agricultural lands as an alternative of chemical fertilizers. However, their effects on the crop production and environmental impacts are still vague. The current study was investigated the property changes of paddy soils in sandy loam and silty loam treated with 1) control (no treatment), 2) chemicals, 3) storage liquid fertilizer and 4) SCB liquid fertilizer located in Gyeong-gi province, Korea. The chemical properties of soils in sandy loam and silty loam before the treatment were similar with the ones in the average paddy fields in Korea. Contrary to this, the amount of available phosphorus in sandy loam was higher than the one in the average paddy fields. The number of living organisms in sandy loam and silty loam treated with storage liquid fertilizer and SCB liquid fertilizer were higher than the ones in sandy loam and silty loam with no-treatment and chemicals. Significant difference (P<0.05) among the treatments and no-treatment was observed in sandy loam rather than in silty loam. The amounts of heavy metals were the highest in both sandy loam and silty loam treated with storage liquid fertilizer and SCB liquid fertilizer. The comparison of heavy metals showed that the ones in silty loam were little bit higher than sandy loam. The leaf lengths and dry weights of rices were increased over time, however, no significant difference was observed among each treament. In addition, the rice yield in sandy loam treated with SCB liquid fertilizer was higher than the ones in sandy loam. The highest rice yield was obtained from sandy loam treated with chemicals, but there was no significant difference between storage liquid fertilizer and SCB liquid fertilizer. While the rate of nutrient absorption by rices was the highest in sandy loam and silty loam treated with chemicals, there was no significant difference in sandy loam and silty loam treated with livestock liquid manure.

  • Establishment of the LFQC (Liquid Fertilizer Quality Certification) system is very urgent issue for recycling livestock manure as renewable resources in Korea faced with environmental problem of manure application to land due to intensive livestock farming. In this study, we investigated relevant laws and regulations on livestock manure fertilizer, certifications of eco-friendly agricultural products, government policies on livestock manure management to establish reasonable direction of Korean LFQC (Liquid Fertilizer Quality Certification) system. As a result from this study, the liquid fertilizers in 'LFQC' system could be classified as three levels according to the usage patterns in field; 1st. Individual Farm Level (IFL), 2nd. Joint Farm Level (JFL), and 3rd. Commercial Level (CML). And finally, we found some characteristics in 'Main Level-Grading Factors' of liquid fertilizer such as fertilizing value, harmfulness, stability, uniformity, economic effect, storage potential, commercial value, functionality. Those items were considered to be the key factors for the establishment of 'LFQC' system. More research on 'Evaluation Standards' for concrete guideline and on the 'Main Level-Grading Factors' be needed to complete Korean LFQC system.

  • 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.

  • Ozone from a pilot-scale ozone generator was treated on fermented pig liquid manure stored in a storage tank in order to reduce odor substances during the process of fermented liquid manure production. The group of ozone treatment showed one less than the organic matter compared that of the control. The preferable condition for characteristic changes was when the ratio of BOD to COD was less than 1.5. Ozone treatment showed better oxidizing power than control as it removed more suspended solids and had less methyl isobutyl ketone(P<0.05). Odor reduction measured by olfactory method was higher in ozone treatment than in control.
