  • This study was conducted to make a rapid and easy determination for the fertility of liquid pig manure as fertilizer by investigating the contents, and correlation coefficients of various nutrients. Samples were collected from 118 local pig farms in the western area of Jeju in Korea. Electrical conductivity(EC), dry matter(DM), $NH_4-N$ and minerals were determined and the relationships among them were examined. The collected liquid manure samples from 118 pig farms were classified according to the level of DM contents ;< 3% (92 farms), $3{\sim}6%$ (18 farms), $6{\sim}9%$ (5 farms) and>9% (3 farms), based on the collected data, most of the liquid manure coming from the local pig farms contain small amount of dry matter. The dry matter contents appeared highly correlated(p<0.01) with EC, $NH_4-N$, T-P, Ca, Mg and Na, except for K. In addition EC was proportional to $NH_4-N$, T-P, Ca, and Na except fer Mg. The fertilizer component ratio of $NH_4-N$, P and K in liquid pig manure were not constant, resulting in low efficiency for fertilizer. However, the toxic heavy metals of Cu etc. were below the criteria of organic fertilizer and soil contamination evaluation. Therefore, we concluded that both dry matter content and electrical conductivity could be used as an indicator for evaluating the fertility of liquid pig manure.

  • This study was conducted to investigate the changes in physicochemical and microbiological properties during fermenting process of farm-made organic liquid fertilizer made of the mixture of organic materials such as blood meal and molasse during fermenting process. The pH level of organic liquid fertilizer during the ermentation decreased from 7.2 to 4.3. The EC of organic liquid fertilizer was increased from 13.9 dS/m to 99.3 dS/m during the fermentation. The total population of aerobic bacteria decreased from $8.2{\times}10^5$ cfu/ml to $3{\times}10^4$ cfu/ml, but Bacillus spp. increased from $2.1{\times}10^2$ cfu/ml to $4.2{\times}10^3$ cfu/ml during the fermentation. Bacterial isolates were obtained from organic liquid fertilizers and identified by fatty acid-base typing. The Genus Bacillus was dominant as fermenting proceeded. The denaturing gradient gel electrophoresis (DGGE) profile showed changes of bacterial communities in organic liquid fertilizers.

  • 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 ($1.34Mg\;ha^{-1}\;year^{-1}$).

  • The purpose of this study was to evaluate the mixed treatment of compost tea and amino acid liquid fertilizer as a substitute of oil cake for the organic cultivation of maize in Goesan, Chungbuk province. As a result, nitrogen, phosphoric acid, potassium, calcium and magnesium contents of each organic fertilizer were in the order of oil cake > amino acid fertilizer > compost tea. Each of these organic fertilizers had little influence on the change of soil chemical. Individual treatment of amino acid fertilizer and oil cake for weight of an ear as well as all individual treatments for the fresh weight of 100 kernels showed significant increase, compared to the untreated control. For the corn yield of merchantable quality, each treatment of compost tea, amino acid liquid fertilizer and oil cake increased higher 3.9, 5.4 and 5.9% than untreated control, respectively. On the other hand, as a result of mixed treatment of amino acid fertilizer and compost tea, the change of soil chemical property was insignificant. The mixed treatment, Nonetheless, showed significant increase for stem height to 1st ear, grain setting length in an ear, weight of an ear, and fresh weight of 100 kernels, compared to the oil cake as a control. After all, the corn yield of merchantable quality produced by the mixed treatment was 3.9% higher than the control. Therefore, our study would be considered that the mixed treatment of amino acid and compost tea is one of organic materials that can replace oil-cake in maize.

  • The purpose of this study was to determine which fermented liquid fertilizer and application method yields the greatest amount of growth in red pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentum MILL.) plants. Additionally, we investigated which extraction methods produce the most effective fertilizer with the highest levels of mineral nutrients. The liquid fertilizers used in this study were made from fish, bone and fish meal, red pepper leaves, and oil cake, and were extracted using fermentation or water and boiled water. In tomato plants, foliar-application of fermented fertilizer is known to promote more growth than application by drenching, regardless of the number of treatments (once or twice). In our studies, however, drenching with fertilizer promoted growth more effectively than foliar-application in red pepper plants. Studies in both tomato and red pepper have shown that the number of treatments does not significantly alter growth. Liquid fertilizers produced by a fermentation-extraction method promoted greater levels of growth in tomato compared to red pepper, and growth was greater when fertilizers were applied 20 (rather than 40) days post-sowing. Red pepper and tomato shoot fresh weight were affected more by fermented fertilizers than plant height 20 days post-sowing. In red pepper, we observed increased shoot fresh weight when using fermented liquid fertilizers with concentrations of 0.1% or greater. Tomato shoot fresh weight increased similarly in response to fermented fertilizer treatments at the same concentration levels, except those derived from fish. Fermented fish liquid fertilizer was only effective in increasing tomato shoot fresh weight in concentrations exceeding 1%. Red pepper and tomato shoot fresh weight also increased more than plant height in our studies using fermentation liquid fertilizers at 40 days after sowing. Red pepper fresh weight increased with application of bone + fish meal, red pepper leaf, and oil cake fertilizers at concentrations of 0.1%, but not with fish liquid fertilizer in concentrations under 0.5%. Shoot fresh weight in tomato increased with all liquid fertilizers. Growth in red pepper and tomato may be influenced by different kinds of fertilizers due to combinations of macro- and micro-nutrients, or specific macro-nutrients such as nitrogen, phosphoric acid, and potassium. The mineral nutrients found in fish, bone and fish meal, red pepper leaves, and oil cake were not easily extracted by fermentation; thus, liquid fertilizers made using water and boiled water methods more effectively promoted growth in red pepper and tomato due to the larger amounts of macronutrients eluted.

  • To assess fertilizer value of an quasi-aerobically fermented liquid clipped-grass fertilizer, aerobic incubation experiment using two texturally contrasting loam (L) and sandy loam (SL) soils was conducted for 60 days to investigate temporal variations in N mineralization pattern of the liquid fertilizer applied. To do so, the quasi-aerobically fermented liquid clipped-grass fertilizer was prepared, applied to each soil at a rate of 200 kg-N $ha^{-1}$ and aerobically $25^{\circ}C$ in the dark. During incubation, soil water content was adjusted to field moisture capacity (-33 kPa of soil matric potential) by adding distilled water as necessary to maintain their initial weights. At desired time of incubation (0, 1, 5, 10, 20, 40, and 60 days after incubation), soil was sampled and analyzed for inorganic nitrogen ($NH_4{^+}$-N and $NO_3{^-}$-N) concentrations, pH, EC, total carbon contents and total nitrogen contents. Concentrations of $NH_4{^+}$-N began to decrease right after incubation for L soils, and 10 days after incubation for SL soils, while those of $NO_3{^-}$-N began to increase onset of $NH_4{^+}$-N disappearance. The results of this study showed that quasi-aerobically fermented liquid clipped-grass fertilizer could serve as an alternative to chemical N fertilizer.

  • 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.

  • Organic fertilizers are divided into natural organic and synthetic organics. The benefits of natural organic fertilizer were reported from the previous researches. However, the limited research results about clippings as a source of natural organic fertilizers were reported. The objective of the research to investigate effects of liquid fertilizer produced from fermented clippings for creeping bentgrass growth. Liquid fertilizer (LF) produced was used for the research to be compared with Urea and two natural organic fertilizers of different source (NO-1 and NO-2). Creeping bentgrass (Agrostis stolonifera L., L-93) was used for the study. Turfgrass quality was measured by visual evaluation every two weeks from June to October, 2011 using a scale of 1 to 9 (1=worst, 6=acceptable, and 9=best). Turfgrass disease damage was measured by percent of area damaged when a turfgrass disease occurred. LF produced lower damage than NO and urea when temperature was high. Although NO-2 produced the highest or equal to the highest turfgrass quality in June and October, LF had the highest or equal to the highest quality from July to September.

  • Organic fertilizers are divided into natural organic and synthetic organics. The benefits of natural organic fertilizer were reported from the previous researches. The previous researches have reported that clippings are nitrogen source for turfgrass growth. However, the limited research results about clippings as a source of natural organic fertilizers were reported. The objective of the research to investigate effects of liquid fertilizer produced from fermented clippings for creeping bentgrass growth. Liquid fertilizer (LF) produced was used for the research to be compared with urea and two natural organic fertilizers of different source (NO-1 and NO-2). Kentucky bluegrass (Poa pratensis L., Midnight) was used for the study. Turfgrass quality was measured by visual evaluation every two weeks from June to October, 2011 using a scale of 1 to 9 (1=worst, 6=acceptable, and 9=best). LF produced greater turfgrass quality than acceptable quality, especially with the summer period while urea and NO produced lower turfgrass quality than acceptable quality of 6. LF had less quality alteration than urea and NO during the study. Based on the result of the study, LF are more stable to maintain turfgrass quality than urea and NO.
