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), NH₄-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~ 6% (18 farms), 6 ~ 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, NH₄-N, T-P, Ca, Mg and Na, except for K. In addition EC was proportional to NH4-N, T-P, Ca, and Na except for Mg. The fertilizer component ratio of NH₄-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 effects of two dry matter levels of liquid swine manure on dry matter yield and nutritive value of Italian ryegrass, rye and oats, and the chemical c㏊racteristics of soil in Jeju. This experiment tested in split plot design. Three forage crops (Italian ryegrass, rye and oats) were the main plot and four fertilizers (no fertilizer = T0, chemical fer tilizer = T1, liquid swine manure with DM 2.7% = T2 and liquid swine manure with DM 5.9 % = T3) were the sub plots. Yield and nutrient contents of forage crops and soil properties were determined. Application of liquid swine manure containing 5.9 % dry matter resulted in highest DM yiel d in all three forage crops species compared with the other treatments (p〈0.01). Crude protein content (%) and crude protein yield (㎏/㏊ ) of forage crops were highest in rye compared with the other forage crops species (p〈0.01). K and Mg contents of soil were higher (p〈0.01) in rye t㏊n in the other specie s while Na contents was higher (p〈0.01) in Italian ryegrass t㏊n others. Mg content of soil appeared higher in rye t㏊n in the others and higher (p〈0.05) in forage crops applied with liquid manure containing 2.7% DM compared with the other species. NO ₃?N contents in soil was lower in rye t㏊n the other species and higher in species with chemical fertilizer. These findings indicate t㏊t most of liquid swine manure produced on local pig farms containing low levels of dry matter and other nutrients suggest a low efficiency of its use as a fertilizer. The liquid swine manure is recommended as a fertilizer for rye production in winter, compared with Italian ryegrass or oat.

The experiment was carried out to determine the effect of lime application rates (0, 4,000 and 8,000 kg/ha) on the growth, yield and chemical composition of Potomac orchard grass [Dactylisglomerafa L.] and Mancher smooth bromegrass [Bromus inermis Leyss.] at the forage field of Seoul National University, Suweon from September, 1983 to October, 1984. 1. The seedling growth and tillering of orchardgrass and smooth bromegrass were significantly improved (P $lt; 0.01) with increasing liming rates. 2. The dry matter yield of smooth bromegrass was significantly increased (P$lt;0.01) with increasing rates of lime application, but that of orchardgrass was not increased. 3. The growth of smooth bromegrass was depressed by weeds more than that of orchardgrass (P$lt;0.01). However, increasing lime application significantly reduced the weed development of smooth bromegrass plot (P$lt;0.01). 4. At the end of the experiment, no ground cover difference was found between no liming and liming plots of orchardgrass, but there was a great difference in ground cover between those of smooth bromegrass. 5. The crude protein, Ca, and P contents of both orchardgrass and smooth bromegrass were increased as Liming rates increased, while crude fiber content decreased. The average crude protein content of smooth bromegrass was 3.09% higher than that of orchardgrass. From the results of the experiment, it can be concluded that smooth bromegrass has a higher lime requirement than orchardgrass. Therefore, liming is primarily needed to establish smooth bromegrass successfully.

본 연구는 말 방목에 따른 초지 부실화 및 이용연한이 짧아진 초지에 대해 생산성을 높이기 위해 오차드그라스+페레니얼 라이그라스 혼파 경운초지(paddock No.39)과 보파초지조성(paddock No.44) 및 톨 페스큐 단파 경운초지(paddock No.64)를 조성한 후 2016년과 2017년에 거쳐 목초율, 건물생산성 및 사료가치에 대해 조사한 결과는 다음과 같다. 목초비율은 No.64가 2016년 81%, 2017년 75%로 No.39 67% 및 60%, No.44 58% 및 54%보다 최대 21%나 높았다. 연평균 건물생산량은 No.64구가 13,234kg/ha로 가장 높았으며 그 다음 No.39, No.44로 각각 10,636kg/ha 및 10,235kg/ha 순이었다. 조단백질 함량은 No.39(갱신혼파) 12.16%로 가장 높았고, N0.44(보파혼파)와 No.64(톨 페스큐 단파)가 각각 10.75%와 10.73%를 보였다. NDF함량(2년평균)은 No.44구가 55.90%로 No.64 및 No.39 각각 58.42%와 57.00%에 비해 다소 낮았다. ADF함량(2년 평균)은 No.44구가 NDF함량과 동일한 경향인 31.07%로 No.39 및 No.64 각각 31.71% 및 32.65% 보다 낮았다. P의 함량(평균값)은 No.44 및 No.64구가 0.29%로 No.39 0.27% 보다 높았고, K 함량은 2.23%~3.83%의 농도를 보였으며 처리 간에는 No.44구가 2년 평균 3.03%로 가장 높았고 그 다음 No.39와 No.64가 각각 3.01% 및 2.81%를 보였다. Ca함량(2년 평균)은 No.39구가 0.28%로 가장 높았고 No.44구 및 No.64구가 각각 0.26% 및 0.22%를 보였다. Mg함량(2년평균)은 No.39구가 0.26%로 No.44 및 No.64구 0.22% 보다 높은 함량을 보였고, Na함량(2년평균)은 No.64, No.44 및 No.39구에서 각각 0.03%, 0.05% 및 0.063% 순의 높은 함량을 보였으며, 연도 간에는 큰 편차가 없는 것으로 조사되었다. 결과를 종합해보면 목초의 영양가치면에서는 갱신혼파(No.39)가 높았으나 목초 구성률 및 생산성을 고려하면 톨 페스큐 단파구(No.64)가 바람직한 것으로 났다. In this study, we created grassland establishment(paddock No.39), grassland improvement(Paddock No.44), and tall fescue seeding(paddock No.64), and the rate botanical composition, DM yield, nutritive value were examined through 2016 to 2017. The rate of botanical composition was 81% in 2016, 75% in 2017, up to 21% higher than No.39 67%, 60%, No.44 58% and 54%. The annual average DM yield was the highest at 13,234kg/ha in the district, followed by No.39, No.44, followed by 10,636kg/ha and 10,235kg/ha, respectively. The crude protein content was the highest at No.39 12.16%, with No.44 and No.64 showing 10.7%, respectively. NDF content (average for two years) was 55.90% in No.44 and No.39, slightly lower than 58.42% and 57.00%, respectively. The two-year ADF average content was 31.07% for the same trend as the NDF capacity in the No.44, below 31.71% and 32.65%, respectively. To sum up the results, Although there was a high level of incentive sowing plot(No.39) in nutritive value, considering the botanical composition and productivity of the pasture, it is also deemed desirable to have a tall fescue plot(No.64).

본 연구는 부실초지를 갱신을 통해 목초율, 목초생산성 및 방목에 의한 증체효과를 규명하기 위하여 수행하였다. 그 결과는 다음과 같다. 방목개시전인 1차(5.11) 조사 시에는 No.64구가 목초비율 81%로 가장 높았으며, No.39 71%, No.44 65% 순이었다. No.64구를 제외하고는 2차 및 3차 조사 시 목초율이 55%내외로 비교적 낮았다. 연가 총 건물생산량은 No.44가 13,459kg/ha로 가장 높았으며 그다음 No.64 및 No.39로 각각 13,232kg/ha, 12,042kg/ha의 생산성을 보였으나 오차드그라스와 페레니얼 라이그라스 혼파구인 No.44구와 No.39구는 하고현상 등으로 인해 2차 조사 이후 급격한 수량감소를 보였다. $10,000m^2$ 당증체량은 No.39구가 70kg으로 No.64 및 No.44 각각 47.5kg과 36.2kg을 큰 격차를 보였으나 일당증체량은 No.39와 No.44는 각각 1.09kg과 1.08로 거의 같은 증체량을 보였고 No.64도 1.03kg의 일당증체량을 보였다. This study was carried out to identify the effect of the rate of botanical composition, dry matter yield and liveweight gain of horse by renewing low productive pasture. According to the first survey (5.11) before grazing, No.64 was the highest at 81%, followed by No.39 71%t and No.44 65%. For the second and third surveys, the rate of pasture was relatively low, except for No.64. Annual total DM production was the highest at No.44 13,459 kg/ha, then with No.64 and No.39, productivity was 13,232kg/ha and 12,042kg/ha, respectively. No.44 and No.39, the confluence of orchardgrass and perennial ryegrass, showed a sharp decline because of summer depression after the second survey. The livestock growth rate per 10,000 square meters was 70kg, compared with 47.5kg and 36.2kg, respectively. The daily livestock gains in No.39, No.44, and No.66 was 1.09 kg, 1.08 kg and 1.03 kg, respectively.

For 63 soil series distributed in Jeju Island, natural uncultivated soils in each soil series were collected, and their physicochemical properties and their concentrations of 19 heavy metals including 8 heavy metals which are regulated by Korean Soil Environment Conservation Law, were analyzed. Moreover, the correlations between physicochemical properties and heavy metal concentrations, and between heavy metal concentrations were analyzed. The heavy metals distributed in the higher concentrations and the lower concentrations with arithmetric mean value, were Mn(730 mg/kg) and Ba(493 mg/kg), and Hg(0.146 mg/kg) and Tl(0.096 mg/kg), respectively. The correlations between pH(H2O) and heavy metals(Hg, Ni, Co, Se), between pH(NaF) and heavy metals(Hg, Ba, Se, Tl), and between organic matter content and heavy metals(Hg, Tl) were significant at the 0.01 level. From the correlations between heavy metal concentrations, there were 22 where there were significant at the 0.01 level and they showed positive correlation. Among those, the heavy metals showing the correlation higher than r=0.5, were Sb-V(0.878), Mo-Sn(0.867), Co-V(0.654), Co-Sb(0.648), Be-Sn(0.546), and Sn-Tl(0.528).
