  • 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

  • The application of animal manure on farm fields is one of the most economical ways. However, the continuous application of manure in paddy fields might change soil properties influencing the growth of rice plant. Thus, this study was conducted to investigate the changes in selected chemical and biological properties of soils and rice production as affected by the applications of two different fertilizer sources, which were the consecutive applications of liquid swine manure (LSM) and chemical fertilizer (CF), during the three experimental years, from 2012 to 2014. Application amount of LSM was based on 100% of nitrogen fertilizer recommendation rate for rice cultivation estimated by soil testing. Plant height and tiller number in rice at the first year of liquid swine manure manure plot were lower than those of chemical fertilizer plot. Height and tillers of rice in liquid swine manure plot were higher than those of rice in chemical fertilizer plot after consecutive application for 3 years. Rice yield In the first year of application was decreased by 7% than that of chemical fertilizer, but the yield of rice in the third year of application in LM 100% plot was increased by 8% compared to the chemical fertilizer. Toyo-taste value of milled rice in LM 100% was decreased by increasing of protein contents and decreasing rate of perfect grain. The K and Zn contents in the soil were increased in the plots of consecutive LSM application. The results implied that the liquid manure may neither decrease the yield of rice and nor increase soil properties except K and Zn in the soil, and decrease rice quality.

  • This study was conducted to investigate the effects of concentrated pig slurry and byproduct liquid fertilizer on the growth and yield of chinese cabbage. The experiment was conducted in a rain-shelter house which was installed in the agriculture farm. Plants were fertilized with concentrated slurry (CS), byproduct fertilizer (BF), mixture of concentrated slurry and byproduct liquid fertilizer (CS+BF), combined organic and chemical fertilizer (CS+BF+BF) and chemical fertilizer (CF) as control. 1. The pH level of byproduct liquid was decreased from the 3rd to the 7th day and increased 9 day to 14th day, but pH of concentrated slurry (CS) was not greatly varied. EC of concentrated slurry (CS) and byproduct liquid was increased gradually during the fermentation. 2. The concentrated slurry (CS) was low in phosphorus, calcium, magnesium, rich in potassium and unbalanced as a low nitrogen and high potassium. But byproduct liquid fertilizer was balanced in nitrogen and potassium ratio. 3. The leaf number, head height, head width of chinese cabbage in treatment with organic and chemical fertilizer (CS+BF+N) showed significant difference compared with control. The plant and head weight of chinese cabbage in treatment of concentrated slurry was severely decreased, but that in treatment organic and chemical fertilizer (CS+BF+N) were increased 8, 10% compared with control chemical fertilizer (CF), respectively. 4. The content of $K_2O$ in plant tissue and in soil was increased after using concentrated slurry. On the other hand, mineral content of except $K_2O$ did not differ significantly between any of the treatments. In conclusion, organic and chemical fertilizer (CS+BF+N) could improve growth and head weight of chinese cabbage.

  • A liquid waste from methane fermantation was applied on Maize field to determine its effect and optimum application rate on the plant growth. A basal application of liquid waste increased a considerable amount of soil water resulting in an increase of germination. Fresh and dry yields of maize plant increased as the liquid waste application rate increased and same as plant growth. Nitrogen and phosphorus components in plant and soil showed the same tendency as the yields. The result indicates that the liquid waste is potentially useful source for a fertilizer and irrigation water.

  • Objective of this study was to investigate characteristics of inorganic components contained in liquid fertilizer produced using seaweed by adding microorganisms and molasses. Addition of dry yeast to liquid fertilizer resulted in little change in pH and considerable increase in EC with high EC value compared to other liquid fertilizers which have microorganisms additives. Also, it was appeared that the dry yeast-added treatment had higher $NH_4-N$ concentration than other treatments. In the other hand, addition of molasses resulted in low pH compared to the control which has no additives, and EC was not different depending on the amount of molasses. $NH_4-N$ concentration in the 2% molasses added treatment was lowest and it showed a significant difference in the no and 1% molasses added treatments. In conclusion, it was shown that addition of dry yeast to liquid fertilizer increased ammonium nitrogen concentration by accelerating nitrogen mineralization, while molasses has an effect of inhibiting nitrogen mineralization. With application of organic liquid fertilizer containing seaweed increased the fresh weight of chinese cabbage.

  • This study was conducted to evaluate the effect of developed SCB (DSCB) liquid fertilizer produced by adding N, P and K at SCB liquid fertilizer on the growth of kentucky bluegrass. Two different N sources used in DSCB were ammonium sulfate (DSCB-A) and urea (DSCB-U), respectively. Fertilizer treatments were designed as follows; non-fertilizer (NF), control (CF; chemical fertilizer), DSCB-A1 ($200\;ml{\cdot}m^{-2}$DSCB-A), OSCB-A2 ($250\;ml{\cdot}m^{-2}$DSCB-A), OSCB-U ($250\;ml{\cdot}m^{-2}$DSCB-U) and CF+SCB (CF+$250\;ml{\cdot}m^{-2}$SCB). Every treatment was arranged in a randomized complete block design with three replications. In kentucky bluegrass, turf color index, chlorophyll index, dry weight and nutrient contents were measured. Results were as follows; It was hardly affected by DSCB and SCB application in investigation of chemical properties of soil. Turf color index and chlorophyll index in DSCB and SCB treatments were increased by 1~2% and 19~24% than NF, respectively and similar to CF. As applied with DSCB and SCB, dry weight of DSCB-U and CF+SCB was increased by 36% and 10% than CF, respectively, but similar to that of OSCB-A1 and DSCB-A2. Evaluated with turf quality and growth, DSCB-U was the best in all treatment and OSCB-A1 the most efficient. These results indicated that applications of OSCB and SCB promoted turf quality and growth of kentucky bluegrass or similar to CF, so that they were expected to replace chemical fertilizers.

  • As part of the recycling methods, residual food through the anaerobic fermentation process was decomposed into methane gas and fermentation liquid. The research was conducted to measure the effect of application of fermentation liquid on chemical properties of soil and plant growth according to application rate and separate manure at the base of nitrogen in fermentation liquid. The fermentation liquid contained 0.52% nitrogen was applied in treatments by standard fertilizer. The treatments were composed of the control only with chemical fertilizer and N-50, N-100-4, N-100-8 were each of applied with 50, 100(6 times), 100(3 times)% of fermentation liquid contrast to standard fertilizer. Properties of fermentation liquid was high EC because of waster soluble organic compounds as well as much of salts and also contained a lot of suspended solid. The changes of soil chemical properties little occurred in before and after of experiment but EC and content of ex. Ca in soil were increased. Fresh weigh in treatments applied with fermentation is high than that of control but the difference between treatments little showed. The above result means if fermentation liquid be used instead of chemical fertilizer the volume of used fermentation liquid will be reduced by 50% of present standard fertilizer.
