  • This experiment was carried out to determine the forage yield and mineral contents of silage corn(Zea mays L.), and N balance, soil chemical characteristics and nitrate-N level in infiltration water by different types and N rates of liquid manure applied. Seven treatments consisting of chemical fertilizer $200kg\;N;ha^{-1}$, liquid cattle manure 200, 320 and $440kg\;N;ha^{-1}$, liquid swine manure 200, 320 and $440kg\;N;ha^{-1}$ were arranged in a randomized complete block design with three replications. The results obtained at National Livestock Research Institute, RDA, in Suweon from May 1997 to Aug. 1997 are summarized as follows : There were no significant differences in percentage of dry matter among the treatments, but significant dry matter yield differences were found (P<0.05), and also the mean dry matter yield of liquid swine manure plot was higher than that of liquid cattle manure plot. Potassium, calcium and magnesium contents of silage corn increased with increasing liquid manure application rates (P<0.05). Nitrate-N content of silage corn in the liquid cattle manure treatments was not influenced by liquid manure application rates, but that in the liquid swine manure treatments increased with increasing the N rates of liquid manure application. pH and contents of exchangeable canons of the soil after experiment were raised by increasing the amount of liquid manure application. Available $P_2O_5$ content in topsoil(0-10cm) was highest as $340mg\;kg^{-1}$ at the plot of liquid swine manure $440kg\;N;ha^{-1}$. Concentration of nitrate-N in infiltration water increased at the plot of liquid swine manure $440kg\;N;ha^{-1}$. Amount of nitrogen balance increased with increasing liquid manure application rates. Based on the results of this experiment, it is suggested that the mean dry matter yield of liquid swine manure plot was higher than that of liquid cattle manure plot, and the amount of nitrogen balance increased with increasing liquid manure application.

  • This study was conducted to investigate the influence of the mixed application of chemical fertilizer (CF) and liquid swine manure (LSM) on the agronomic characteristics, dry matter yield, amino acids, minerals, and free sugars in cultivating Sorghum ${\times}$ Sudangrass hybrid (SSH) on paddy soil. The field experiment was designed in a randomized block design with three replications and consisted of CF 100% (C), CF 70% + LSM 30% (T1), CF 50% + LSM 50% (T2), CF 30% + LSM 70% (T3), and LSM 100% treatment (T4). The application of LSM was based solely on the nitrogen. Plant length, leaf length, leaf width and number of leaf were significantly higher in T4 (p<0.05), but stem diameter did not show significant differences among treatments. Stem hardness increased significantly (p<0.05) as the LSM application rate decreased, but sugar degree decreased significantly (p<0.05) as the LSM application rate decreased. Fresh yield, dry matter yield and TDN yield were the highest in T4, whereas the lowest in T2 (p<0.05). Crude protein, crude fat and crude ash were the highest in C, T4 and T2, respectively (p<0.05). However, NDF and ADF did not show significant difference among treatments. Crude fiber decreased significantly (p<0.05) as the LSM application rate increased. The total mineral content was decreased significantly (p<0.05) as the LSM application rate increased. Total amino acid content was higher in the order of T1> C> T3> T4> T2 (p<0.05). Free sugar content increased significantly (p<0.05) as the LSM application rate increased. The analysis of all the above results suggests that the application of liquid swine manure is very effective, considering the yield performance and the content of sugar degree and free sugar. In addition, liquid swine manure may be possible to grow Sorghum ${\times}$ Sudangrass hybrid without chemical fertilizer.

  • Manure management is a top priority on both dairy and swine farrns at present. This experiment was carried out to determine the effect of different types and N rates of liquid manure on forage yield and quality of oats(Avena sativa L.) in Suweon, 1997. Seven treatments consisting of chemical fertilizer $120kg\;N\;ha^{-1}$, liquid cattle manure 120, 240 and $360kg\;N\;ha^{-1}$, and liquid swine manure 120, 240 and $360kg\;N\;ha^{-1}$ were arranged in a randomized complete block design with three replications. As increasing N rate of the liquid manure, the plant height was increased, but dry matter content of oats was decreased as increasing liquid manure N rate. There were significant differences in dry matter yield of oats among the liquid manure N rates(P<0.05). Crude protein(CP) content of oats ranged from 14.7 to 24.1% (P<0.05), and CP yield was orderly ranked as liquid swine manure $360kg\;N\;ha^{-1}$>liquid cattle manure $360kg\;N\;ha^{-1}$>liquid swine manure $240kg\;N\;ha^{-1}$(P<0.05). Acid detergent fiber(ADF) content of the liquid cattle manure treatment showed a slightly higher than that of the liquid swine manure treatment(P<0.05). Neutral detergent fiber(NDF) content of the liquid cattle manure treatment was lower than that of the liquid swine manure treatment(P<0.05). Relative feed value(RFV) of the liquid cattle manure treatment decreased with increasing liquid manure N rates compared with that of the liquid swine manure treatment. Based on the results of this experiment, it is indicates that to increase the N rates from liquid manure application could be obtained from the increase of forage yield.

  • Liquid manure fertilizer drived from pig slurry is a valuable source of nutrients for crop production. However, there is no study for environmental assessment regarding microbial quality to apply liquid manure fertilizer. Therefore, this study aimed at quantifying the level of environmental impact on fecal coliform (Escherichia coli or E. coli ) survival in saturated soil such as paddy field. Surface water samples were collected up to 168 and 11 hours under natural sunlight and artificial ultraviolet radiation, respectively. The inactivation rate of E. coli under natural sunlight increased gradually after 48 hours. However, the inactivation rate of E. coli under artificial ultraviolet radiation increased linearly over time. Our findings suggested that the ultraviolet radiation is the limited factor on E. coli survival in surface water of saturated soil. This result will provide useful and practical guideline to applicators of agricultural soil in deciding appropriate handling and time frames for preventing pollution of water quality for sustainable agriculture.

  • Of all the nutrients in liquid manure, N has the greatest potential both for the environment and for increasing forage yields. This experiment was carried out to determine the effect of different types and N rates of liquid manure on mineral content and nitrate-N of oats(Avena sativa L.), soil chemical characteristics in Suweon. Seven treatments consisting of chemical fertilizer $120kg\;N\;ha^{-1}$, liquid cattle manure 120, 240 and $360kg\;N\;ha^{-1}$, liquid swine manure 120, 240 and $360kg\;N\;ha^{-1}$ were arranged in a randomized complete block design with three replications. Compared with the plot of chemical fertilizer, increasing liquid manure N rates increased mineral contents of oats. Nitrate-N contents of oats were ranged from 1,881 to $2,605mg\;kg^{-1}$ in all treatments, which was orderly ranked as chemical fertilizer>liquid cattle manure $360kg\;N\;ha^{-1}$> liquid swine manure $240kg\;N\;ha^{-1}$. Contents of exchangeable cation of the soil were appeared to be higher with increasing liquid manure N rates. Amount of total-N and inorganic-N in soil affected by increasing liquid manure N rates, and there was the highest at liquid swine manure $360kg\;N\;ha^{-1}$ among the treatments. Nitrate-N concentration in infiltration water was not remarkably variable during the experimental period. Based on the results of this experiment, it is suggested that the amount of nitrogen in soil was orderly ranked as liquid swine manure $360kg\;N\;ha^{-1}$, followed by liquid swine manure $240kg\;N\;ha^{-1}$.

  • This experiment was conducted to evaluate the effect of liquid manure source, application rate and time on the agronomic characteristics and forage yield of winter rye. The experimental design was a randomized complete block design. The treatments were : CFB150=chemical fertilizer(CF) 150 N as basal, CFS150=CF 150 N as split application (75+75), SLB150=swine liquid (SL) 150 N as basal, SLS150=SL 150 N as split application (75+75), SLB300=SL 300 N as basal, SLS150=SL 300 N as split application(150+150), CLB150=cattle liquid (CL) 150 N as basal, CLS150=CL 150 N as split awlication(75+75), CLB300=CL 300 N as basal, CLS150=CL 300 N as split application(150+150). Heading date of the plant was observed on the 17th of April fur both chemical fertilizer and swine liquid, and on the 16th of April for cattle liquid. Stay green of chemical fertilizer was higher than others because of high crude protein content. Leaf was darker in high nitrogen fertilizer treatments than low N treatments. However lodging resistance was poor as nitrogen fertilizer was increased. Dry matter (DM) content of rye at chemical fertilizer was lower than liquid manure. DM yield of chemical fertilizer treatments were highest among the fertilizer source. However, DM yield of rye with application was all most same at different N application methods. The crude protein (CP) content and yield for chemical fertilizer was significantly higher than liquid manure. CP yield using split application was higher by 16% and 28%, compared to basal application. Based on the results of this study, forage production of liquid manure was lower, compared to chemical fertilizer. And split application was superior to basal application forage and protein yields, and high protein.

  • This study was carried out to investigate the growth characteristics, yield and chemical compositions of whole crop barley (Hordeum vulgare L.) according to mixing ratio of chemical fertilizer (CF) and liquid swine manure (LSM) in the paddy field cultivation. The experimental design was arranged in a randomized block design with five treatments and three replications. The manure fertilizer ratio of five treatments were CF 100% (T1), CF 70% + LSM 30% (T2), CF 50% + LSM 50% (T3), CF 30% + LSM 70% (T4), and LSM 100% (T5) of whole crop barley. At this time, the application of liquid swine manure was based solely on the nitrogen. Plant length was higher at T1 as compared to other treatments (T2, T3, T4 and T5). Fresh yield, dry matter yield and total digestive nutrients (TDN) yield were the highest in T1, whereas the lowest in T5 treatment (p<0.05). Chemical compositions (crude protein, crude fat, neutral detergent fiber, acid detergent fiber and TDN) did not show significant difference among treatments. Ca and Na contents were significantly lower at T1 as compared to other treatments (T2, T3, T4 and T5). However, Mg and P contents were significantly higher at T1 as compared to other treatments(p<0.05). There was no significant difference in total free sugar content among T2, T3, T4 and T5 treatments, but the chemical fertilizer (T1) was significantly lower than the other treatments (p<0.01). Considering the above results, liquid swine manure application showed lower dry matter yield and TDN yield than chemical fertilizer, but higher free sugar content. Therefore, in order to increase the productivity of whole crop barley, it is considered desirable to mix liquid fertilizer with chemical fertilizer, taking into account the decomposition rate and insufficient components (P, K) of the liquid swine manure.

  • A major problem within the agricultural/farming community concerns the enormous amount of manure produced by livestock; one possible solution to this problem is to use the animal slurry as a liquid fertilizer. While there are several areas where this fertilizer could be used, one promising area of application is within chestnut tree fields. However, since most of these fields are located on slopes of varying grades and not on flat land, a different spread system is required. Generally, chemical fertilizer is spread in the chestnut field manually by hand; not only does this require a great deal of manpower it is also very difficult and hard work. In our lab experiment, we investigated the relationship between the amount of fertilizer spread and the length of pipe used at varying pressure levels. The hose in our system utilized PVC piping with evenly spaced holes for the fertilizer to dissipate. We initially found that the amount of spread was greatly reduced by reducing pipe pressure. While the difference of the amount of spread during fertilizing was not great, we did find that the reduction of the spread could be correlated to the frictional resistance of the inner lining of the pipe. Based on this, we hypothesized that an increase in pipe pressure would yield a consistent spread. Additionally, a similar outcome could be obtained by regulating the distance of the holes in the pipe and their diameter.

  • This study was conducted to evaluate the effect of swine liquid manure (SLM) on rice grown in Yeonggwang-gun in 2008. The treatments consisted of SLM and chemical fertilizer (CF) based on the recommended amount of nitrogen (11 kg N $10a^{-1}$). The Total N content of the SLM used was 2,881 mg $L^{-1}$. Plant height at the early stage of growth and tiller number were not significantly different between plots applied with swine liquid manure and those with chemical fertilizer in all areas. Plant height at the later stage of growth, lodging and yield were not significantly different between plots applied with swine liquid manure and those with chemical fertilizer in three areas (Baeksu, Gunnam, Beopseong). Plant height at the later stage of growth, as well as lodging were higher in SLM plots than in chemically fertilized plots in Yeonggwang and Yeomsan. However, grain yield was lower in SLM plots than in chemically fertilized plots in these areas. Soil organic matter content and exchangeable cations increased in the swine liquid manure applied plots. Moreover, heavy metal content did not increase in the plots treated with swine liquid manure. Further research to determine the suitable rate of swine liquid manure is needed to reduce lodging damage and to increase the yield and quality of rice.

  • This study was performed out to investigate the influence of the mixed application of chemical fertilizer (CF) and liquid swine manure (LSM) on the growth characteristics, dry matter yield, amino acids, minerals, and free sugars in cultivating silage corn on paddy soils. The field experiment was designed in a randomized block design of 3 repetitions with CF 100% treatment (C), CF 70% + LSM 30% treatment (T1), CF 50% + LSM 50% treatment (T2), CF 30% + LSM 70% treatment (T3), and LSM 100% treatment (T4). At this time, the application of LSM was based solely on the nitrogen. Ear length, ear circle, stem diameter, and stem hardness of the silage corn did not show significant differences between treatments. Fresh yield, dry matter yield and TDN yield were highest in T3, whereas the lowest in C treatment (p<0.05). Crude protein, crude fat, and crude ash content were significantly higher in T1, C, and T4 treatment, respectively (p<0.05). However, NDF, ADF and crude fiber content did not show significant difference between treatments. The total mineral content decreased significantly (p<0.05) as the LSM application rate increased. Total composition amino acid content was higher in the order of T1 > T2 > C > T4 > T3 treatment (p<0.05). Free sugar content was higher in the order of T1 > T3 > T4 > T2 > C treatment (p<0.05). Based on the above results, suggests that the mixed application of chemical fertilizer 30~50% and LSM 50~70% (T2 and T3) is the most effective, considering the yield performance and the content of sugar degree and free sugar affecting silage.
