  • 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.

  • 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.

  • 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.

  • 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.

  • We studied the possibility to produce solid fuel using cattle manure and to apply TAO (Thermophilic Aerobic Oxidation) process of solid-liquid separation fraction. The physiochemical compositions of cattle manure solid fuel chip were analyzed as water 0.12%, low calorific value 3,510 kcal/kg, ashes 11.9%, chlorine 0.82%, sulfur dust 0.5%, mercury non-detection, cadmium 1.0 mg/kg, lead 2 mg/kg, arsenic non-detection. In treating cattle manure with TAO reactor the internal temperature of the reactor was increasing higher and $50^{\circ}C$ and over was maintained after 20 hours on. The physiochemical compositions of liquids increased from pH 7.3 to pH 9.18 and EC decreased from 4.6 to 3.48 mS/cm in treating process of cattle manure with TAO reactor. COD and SCOD decreased from 16,800 to 10,400 mg/L, from 4,600 to 2,040 mg/L respectively, which showed about 38% and 56% of remove efficiency respectively.

  • The dramatic increase in both swine and cattle production in Korea has presented problems related to protection of water resources. Animal wastes are a potentially valuable source of plant nutrients. Modern liquid waste management plans for a livestock housing need to focus on the slurry aeration and composting control methods and cost effective equipments. Recent developments in the animal manure liquid composting make it possible to improve the manure more easier to handle, reduce the odorous, labors and bedding materials, kill the weed seeds etc. However, there are some disadvantages, the aerator consumes much electrical power and initial cost is high. To solve these problems, this study is intended to develop a key points such as slurry aeration and dilution, liquid waste composting equipments.

  • 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 $240kg\;N\;ha^{-1}$.

  • A manure management plan is important for all dairy operations. This experiment was conducted to determine the effect of different nitrogen(N) application rates of liquid cattle manure on the forage quality, N recovery, and total forage yields of corn-oats cropping system and soil properties at the National Livestock Research Institute, RDA, Suweon in 1997. Eight treatments consisting of no fertilizer, chemical fertilizer $320kg\;N\;ha^{-1}$ as urea, the continuous applications of 320, 640 and $960kg\;N\;ha^{-1}$ as liquid cattle manure(LCM), the residual effects of 200, 400 and $600kg\;N\;ha^{-1}$ as liquid cattle manure were arranged in a randomized complete block design with three replications. Mean plant height of fall sown oats was 70 and 61cm at the continuous application and the residual effect plots, respectively. Mean dry matter percent of fall sown oats at the residual effect plots was higher by 0.9% than that of oats at the continuous application plots, but there were no differences among all treatments. Mean crude protein(CP), acid detergent fiber(ADF), and neutral detergent fiber (NDF) contents of fall sown oats at the continuous application plots were higher by 1.0, 1.6, and 3.1%, respectively, than those of the residual effect plots. Also, there were significant differences among treatments (P<0.05). Total forage dry matter yields of corn and oats cropping system were ranged from 11,365 to $25,668kg\;ha^{-1}$ among the treatments. The yield was orderly ranked as LCM $960kg\;N\;ha^{-1}$ > LCM $600kg\;N\;ha^{-1}$ > LCM $640kg\;N\;ha^{-1}$ > LCM $400kg\;N\;ha^{-1}$ (P<0.05). Compared with the control, manurial value(MV) was 158 and 139% for the plot of the LCM $960kg\;N\;ha^{-1}$ and that of the LCM $600kg\;N\;ha^{-1}$, respectively. N recovery percent of fall sown oats was the highest at the plot of the LCM $200kg\;N\;ha^{-1}$ by 50%, and then was higher in order of the LCM $400kg\;N\;ha^{-1}$, LCM $600kg\;N\;ha^{-1}$, and LCM $320kg\;N\;ha^{-1}$. Contents of exchangeable cation in the soil of the residual effect plots was higher than that of the continuous application plots. These results suggest that the LCM $600kg\;N\;ha^{-1}$ may be the most effective in total forage dry matter yields, manurial value, N recovery, and utilizing liquid manure N under the corn and oats double cropping system.

  • 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 performed to investigate situation of livestock manure generated from Kangwon-do and to evaluate its composting probability. The scale of livesrock-farming is bigger and bigger in Korea. Regulation based on the heads of livestock is slightly different from that based on livestock-farming household. So it is needed ro evaluate regulations for livestock head and livestock-farming household. Composting and liquid fertilization were thought to be appropriate technologies to the trearment of Korean cattle and pig manures, respectively. Generation quantity of pig manure was the greatest among pig, Korean cattle, cow and chicken manures. Pig manure generated the greatest amounts of BOD in Kangwon-do. Pig manure contained nitrogen, Korean cattle manure contained $K_2O$, and chicken and pig manures contained $P_2O_5$ in great amount. Alternative ratio of livestock manure to crops-fertilizer was 51% for nitrogen, 38% for $K_2O$, and 34% for $P_2O_5$.
