Nowadays, sustainable and environment-friendly agriculture has become an important issue all around the world, and repeated applications of mineral and/or organic fertilizer will probably affect mineral nutrient dynamics in soil in the long term but only a limited number of observations are available. This study was carried out to investigate whether there is any influence of different fertilizer management for red pepper (Capsicum annuum L.) cultivation on soil physicochemical properties, leaf mineral content, yield and fruit quality in the aspect of long-term practice in open field condition. NPK, NPK+compost, compost only, and unfertilized control plot were included in the treatments. The application of chemical fertilizer and/or compost repeated annually for 17 years from 1994 to 2011. Soil organic matter content was higher in compost treatments than in no-manure treatments. Available phosphate and the yield of red pepper were highest in NPK+compost treatment followed by NPK (chemical fertilizer), compost, and control. The results indicate that in the long term, nitrogen supply is still needed for increasing red pepper yield, but reduction in the use of chemical fertilizer could be also possible with the proper application of compost.

A field experiment was conducted to investigate the effect of long-term (21-year) fertilizer and compost treatments on the yield of red pepper and chemical properties in top-dong, Suwon. Six treatments were chosen for this work: No fertilization (No fert.), NPK fertilizers (NPK), NPK and compost (NPK+Compost), NP and compost (NP+Compost), NK and compost (NK+Compost), PK and compost (PK+Compost). The yield of red pepper for 21 years indicated the significant differences among the No fertilization, the PK+Compost, and other treatments. The relative yield index was 13% and 59% respectively, for the No fertilization and the PK+Compost if the average yield of red pepper for the NPK regards $20,048kg\;ha^{-1}$ as the yield index with 100%. Soil organic matter at the compost applied treatments significantly increased compared with the No fert. and the NPK. The average increase rates of soil organic matter by applying the compost ranged from 0.69 to $0.73g\;kg^{-1}\;yr^{-1}$. Available phosphate content in soil appeared the significant increase all treatments excluding the No fert. It is estimated that the available phosphate in soil was increased by $7.0mg\;kg^{-1}\;yr^{-1}$ by applying compost and $14.2mg\;kg^{-1}\;yr^{-1}$ by applying P fertilizer. Application of K fertilizer or the compost alone, the NPK, the NP+Compost, continuously caused soil K depletion whereas K fertilization plus the compost maintained at a constant level of exchangeable K. The results indicated that the addition of compost to NPK fertilizer is recommended for the maximum stable yield for red pepper and enhancement of organic matter though it is also needed for adjusting of P and K fertilization.

BACKGROUND: The use of green manure and compost as organic fertilizer may increase crop yield and soil fertility due to improved soil nutrient availability and soil organic matter content (SOM). This study aimed to investigate the effects of hairy vetch (Vicia villosa L.) and compost application on red pepper growth, yield, fruit quality and soil health. METHODS AND RESULTS: The treatments were no fertilizer (CON), chemical fertilizer (CF), hairy vetch (HV), and livestock compost+HV (LC+HV). Red pepper seedlings (70 days old) were transplanted and maintained in experimental plots for 140 days. Plant dry weight, micro- and macronutrient contents of plants and soil chemical properties were determined. All fertilizer treatments significantly increased plant dry weight. Fruit yield was significantly highest with HV treatment. As for nutrient content, plants in HV and LC+HV treatments have significantly higher K and Ca contents than the other treatments. Regarding soil properties, HV and LC+HV application significantly altered the soil chemical properties. Significantly higher SOM was observed in HV and LC+HV treated soils. CONCLUSION: The results of this study suggest that short-term application of hairy vetch and compost is an effective alternative to the conventional chemical fertilizer to increase fruit yield red pepper and improve soil health.

Two phases of experiment were conducted to produce compost using sewage sludge and sawdust as mixing materials to determine their chemical properties and the performance of selected test crops. The first phase was done to produce compost as potting media and the second phase was done to test the efficacy of the produced compost. With regard to some chemical properties of the compost, pH was moderately acidic (5.11 to 5.58) while the OM, N, P, and K contents of the compost were 23.8-35.9, 1.12-1.56, 254.9-555.7, and 40.4-62.6, respectively.

For the development of Boxthorn organic cultivation techniques, we investigated effect of several organic compost as a foundation fertilizer and growing plant fertilizer. And we adopted partly opening rain shelter greenhouse to protect anthracnose. In organic compost applying test yield characteristics of 'Mixed organic compost' treatment was the best but in betaine content measurement of dried fruit, 'Mixed organic compost and nitrogen guano' treatment was the best and it's chlorophyll and 100 fruit weight were also better than the other treatments.

양송이의 국내 생산량은 9,732톤으로 5번째로 가장 많이 생산되는 버섯이다. 양송이가 속한 주름버섯속은 리그노셀룰로오스 분해력을 가진 버섯으로 알려져 있다. 양송이의 영양생장과 생식생장동안 기본적으로 셀룰로오스, 해미셀룰로오스, 리그닌 성분의 분해는 변화한다. 우리는 양송이에서 celluase, xylanase, ligninolytic enzyme의 세포외효소 활성도로 효과적인 생물학적 분해력을 가진 균주를 선발하였다. 각 효소의 생물학적 분해는 0.5% CMC-MMP ((malt-mops-peptone), 0.5% Xylan-MMP, 0.5% ligin-MMP 배지에서 14일 동안 균주들을 배양하여 측정하였다. 그리고 배양된 균사체는 0.2% trypan blue에 염색되었다. MMP배지내 각 효소의 생물학적 분해의 효율성에 따라 선발된 균주 18점은 6개로 그룹화되었다. 또한 이 균주들은 볏짚발효퇴비배지에서의 균사생장과 세포외효소 활성도의 연관성을 알아보기 위해 볏짚발효퇴비배지에서 10일, 20일 각각 배양되었다. 본 연구로 ligninolytic enzyme 활성도가 볏짚발효퇴비배지에서의 균사배양과 상관도가 가장 높아 균주내 ligninolytic enzyme의 활성도 비교로 볏짚발효퇴비배지에서 균사배양이 우수한 균주를 간단하게 선발 할 수 있다고 사료된다.

This study was conducted to evaluate the influence of fertilization on characteristics of growth and accumulation of anthocyanin in fruit of Omija (Schisandra chinensis Baillon). Nitrogen supply mainly affected growth of fruit and the anthocyanin content in Omija respective of vegetative growth steps. The anthocyanin content in fruit was significantly low in high N supply and non-fertilization. The conjunctive supply of nitrogen and compost tea resulted in a higher anthocyanin content of fruit, total nitrogen content of leaf, and nitrate in soil. This result implies that nitrogen supply to Omija plant, affects the accumulation patterns of anthocyanin in different ways, e.g. it delays the quantitative biosynthesis at low nitrogen supply during fruit maturation or enhances anthocyanin degradation during the final maturation steps.

The experiment fields consisted of five plots as follows; 2, 4, and $8\;tons{\cdot}ha^{-1}$ citrus skin in combination with starch sludge and pig manure mixing compost (CSSP), $4\;ton{\cdot}ha^{-1}$ fermented pig manure compost (FPMC) treated plot, and untreated control. Plant height and stem diameter were significantly increased by CSSP. Most of all, average tuber weight and tuber yield per plant were significantly increased in 4 and $8\;tons{\cdot}ha^{-1}$ CSSP plots compared to the other plots. Marketable tuber (>50 g fresh weight) yield were superior in order of 4 and $8\;tons{\cdot}ha^{-1}$ CSSP plot, $4\;tons{\cdot}ha^{-1}$ FPMC plot, and $2\;tons{\cdot}ha^{-1}$ CSSP plot.
