  • Livestock manure is known to be the main cause of non-point pollution in agricultural areas. The pollutant reduction ratio of livestock manure recycling to fertilizers was measured in order to analyze the effect on the water quality of the Total Maximum Daily Load (TMDL) system in Korea. The reduction ratio has been applied by theoretical consideration without a survey, and there is no value for Total Organic Carbon (TOC) newly introducing any organic items. The reduction ratio of each pollutant from this study was revealed as follows: TOC, BOD, T-N and T-P were 0.34, 0.60, 0.37, and 0.42 for individual farm and 0.38, 0.61, 0.45 and 0.44 for entrustment facilities, respectively. The reduction ratio of individual farm was surveyed as TOC 0.63, BOD 0.62, T-N 0.42 and T-P 0.32 for liquid fertilizer, and TOC 0.30, BOD 0.64, T-N 0.40 and T-P 0.48 for compost. The total reduction ratio was derived by multiplying the ratio for liquid fertilizer and compost by the respective load. Compared to the pollutant reduction ratio of the individual farm with entrustment facilities marking the higher in liquid fertilizer and the lower in compost. Through this study, we found the difference of pollutant reduction ratio between a livestock manure recycling process and facilities. Although phosphorus is known as a preservative matter, the treatment efficiency of T-P is analyzed to decrease by chemical precipitation.

  • This study was carried out to investigate the effect of slurry composting and biofiltration (SCB) liquid manure application on shoot growth, fruit qualities and soil chemical properties in peach orchard. SCB liquid manure was fertigated ten times from April to October in SCB plot, whereas chemical fertilizer was treated two times as basal and additional fertilizers in control plot. The shoot growth, leaf nitrogen and potassium content, soil exchangeable K, fruit weight and yield were higher in SCB plot than in control. Soluble solid content and acidity, soil organic matter, soil available phosphate and soil exchangeable Mg showed no significant difference between treatments, and the leaf calcium and magnesium content were lower in SCB plot than in control. In conclusion, fertigating SCB liquid manure in peach orchard has positive effects on fruit weight and yield, and it is suggested that periodical soil testing is needed because of the possibility of K accumulation in SCB liquid manure treated soil when the orchard is fertigated based on the soil nitrogen content.

  • In order to use the glutamic acid fermentation residuum in agriculture effectively, comparison experiments of the residua liquid and dried solid, and compost on radish (Raphanus Sativus) and chinese cabbage (Brassica chinesis) were carried out, together with an investigation on some physical property changes of soil brought about by the use of the residua and compost. 1. An equal or somewhat superior effect of the glutamic acid fermentation residua solid and liquid, to urea was observed. 2. Both residua liquid and dried solid, tended to acidify soil and the tendency was observed to be somewhat servere in the latter. 3. The liquid fermentation residuum compounded with minor elements such as iron, manganese, zinc, copper and boron increased the yield of chinese cabbage compared with the liquid residuum alone. 4. Not only as a N, K fertilizer, the liquid residuum of glutamic acid fermentation could also be used as a source for liquid or solid compound fertilizer.

  • A liquid waste from methane fermentation was applied on a pasture of grass-legume mixtures to determine its effect and optimum application rate on plant growth. Fresh yields of the pasture increased as the liquid waste application rate increased, especially markedly increased when the 42 ton/10a of waste was applied only. The NPK components in soil and plant was also higher in the plots of liquid application than that of control. Therefore, the optimum application rate of liquid waste was found to be 42 ton/10a. This result indicates that the liquid waste is potentially useful source for a fertilizer and irrigation water.

  • Over 90% of the livestock excretions were treated and utilized by land application in Korea. Excessive application of the livestock manure as fertilizer has been issued as a main pollutant source in groundwater and watersheds. This study was seasonally conducted to identify the discharging characteristics with a certain artificial rainfall intensity (13 mm/hr) in terms of surface runoff, groundwater, and soil residue mass depending on the livestock manure types. A experimental field was constructed with three different sites that pig liquid fertilizer (LF), cattle manure (CM), and standard (S). The pig liquid fertilizer of 1,200 L and cattle manure of 900 kg were sprayed on each site ($50m^2$). The standard area was firmly prevented from any other contaminants. In the LF site, farmland discharging rate (FDR) was computed as 0.006 in CODcr, 0.015 in TN, and 0.029 in TP, resulted from the mass balance among total injection mass, surface runoff and groundwater. In the CM site, 29% of the nitrogen and phosphorus in each were discharged to the surface, and 64% and 58% of them were remained in the farmland. Surface runoff rate of the CM was higher than that of the LF, resulted from the solid form of the CM.

  • Liquid calcium fertilizer evenly dispersed has been prepared using calcium carbonate powder and several surfactants. The calcium contents of nine fruits and vegetables were compared after spraying the liquid fertilizer onto the leaf of them six times for 2 months. The calcium contents of cabbage and potato increased to 155% and 154%, respectively. In addition, by virtue of the relatively high contents of calcium, rigidities of the texture were also increased, which would result in higher value-added vegetables. Kimchi was prepared using a Korean cabbage sprayed with the liquid calcium fertilizer and its fermentation characteristics were analyzed. A sensory evaluation has been performed to give the best result for a calcium Kimchi fermented for 14 days.

  • 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.

  • Livestock wastes are considered as major environmental pollutants because they contain high concentration of organic materials. In 2001, The Environmental Department reported that stock farmers were increasing as 5.1%/year, which resulted in a gradual increase in livestock wastes generation. The direct disposal of livestock wastes create several environmental problems. Thus, several countries banned the disposal of livestock wastes in environment including aquatic systems. Recently, aeration-based liquid fertilization was considered as potential way for the disposal of livestock wastes. In this study, next generation sequencing (NGS) analysis was used to understand the microbial community changes during liquid fertilization of livestock wastes. Microbial community was compared with liquid fertilizer physicochemical analysis such as $BOD_5$, $COD_{Mn}$ pH, N (Nitrogen), P (Phosphorus), K (Potassium) etc. The physicochemical parameters and bacterial community results pave the way for producing effective livestock-based fertilizer. By comparing the physical characteristics of the manure with microbial community changes, it is possible to optimize the conditions for producing effective fertilizer.

  • A manure management plan is important for all daily operations. This study was conducted to investigate the effect of application level of liquid cattle manure on the soil properties and changes of BOD and COD content in run-off water at the mixtures swards of National Livestock Research Institute RDA Suweon in 1995. The experiment was arranged in a randomized block design with five treatments consisting of no fertilizer chemical fertilizer application of 40, 60 and 80MT/ha as liquid cattle manure. The quantity of run-off for a no fertilizer was the highest of 1,469.4mm but that for a application level of liquid cattle manure of 60MT/ha was the lowest of 1,278.1mm. The change of BOD in run-off for a no fertilizer was the lowest of $19.84m{\ell}/{\;}{\ell}$, but that for a application level of liquid cattle manure of 80MT/ha was the highest of $36.22m{\ell}/{\;}{\ell}$. Change of COD in run-off for a no fertilizer was the lowest of $21.28m{\ell}/{\;}{\ell}$ but that for a application level of liquid cattle manure of 80MT/ha was the highest of $37.51m{\ell}/{\;}{\ell}$. Available phosphorus and total-N content of soil chemical properties was higher at liquid cattle manure than chemical fertilizer.

  • The purpose of this study was to investigate the effects of fertilizer application on the content of functional materials, such as fatty acids and organic acids in perilla leaves. (1) As compared to the controlled with Ammonium sulfate fertilizer, the yield of Perilla frutescens leaves increased by 7.3% and 12.8% of biomass at 2000 and 1000 times liquid respectively, but decreased by 7.6% at 500 times. The lipid and protein contents of perilla leaves were higher than those of Portunus trituberculatus liquid at 1000 times. The average contents of minerals (mg/100g) were as follows; K (638.4) > Ca (561.6) > P (145.4) > Mg (133.5) > Fe (36.2) > Zn (1.9) > Mn (1.6) > Na (1.4 mg). However, the correlation between the controlled with P. trituberculatus liquid was relatively low. (2) The fat-soluble vitamin E content of P. frutescens leaves was 3.4, 3.9, 3.3, and 3.9 mg in the controlled with liquid by 500, and 1000, 2000 times respectively; Vitamin A contents were 6.4, 8.9, 10.9, and 8.5 mg respectively, which was more than twice as much as the corresponding vitamin E content. The water soluble vitamin C contents were 177.9, 172.6, 195.2, and 163.5 mg respectively. (3) Amino acid contents of P. frutescens leaves in 100 g of fresh weight were 3821.7 mg in the controlled with Ammonium sulfate fertilizer and 3918.8, 4054.0, and 4005.4 mg in the controlled with P. trituberculatus liquid at 2,000, 1000, 500 times respectively. Amino acid contents of each controlled group with P. trituberculatus liquid above were as small as 2.5~6.1%, and these contents of amino acid were as follows: Glutaminic acid > Aspartic acid > Leucine > Arginine > Phenylalanine. In further study, it is necessary to develop an effective microorganism and a variety of amino acid fertilizer to supplement the study on new manufacturing.
