  • The blueberry eco-friendly farming requires the soil condition of pH 4.2 ~ 5.2 and high in organic matters for stable growth. Most of soil types of blueberry-growing land in Korea, however, belongs to alkaline soils with low organic matter content. As a result, the eco-friendly blueberry growers use peat moss and sulfur powder heavily to improve the soil condition, but the guideline on the effective use of organic materials was not established yet. Therefore, this sturdy was performed to investigate the effect of increasing soil acidity and organic matters by using organic materials. Among 5 organic materials, the pH of soil was lowest in degradable sulfur + bentonite (pH 4.1) and followed by Peat moss+Chaff+Pine Needlesmixtures(pH 4.5), OrganicAcid +vinegar (pH 4.7), Sulfur powder (pH 4.8), Temperature response Elutioner (pH 5.2). The soil organic matter content were increased in the following order: Peat moss+Chaff+Pine Needlesmixtures (8.4%) > degradable sulfur + bentonite (7.8%) > Organic Acid + vinegar (7.2%) > Sulfur powder ${\fallingdotseq}$ Temperature response Elutioner (6.3%). Although different in the degree, all organic materials treated was recognized a good material for improving soil pH and organic matter content. The plant height and stem diameter of blueberry were no clear difference among 5 organic materials. Another study was carried out to investigate amending soils with organic matter by soil mulching with pine needles for soil surface management in blueberry organic cultivation. The effect of increasing the soil pH by pine needle mulching in blueberry eco-friendly farming was recognized in four test fields. Pine needle mulching for soil surface management in blueberry appeared several advantages, such as improving of soil pH and organic matter content. Therefore, pineneedle mulching in blueberry organic farming is considered as the most efficient means of mulching cultivation for amending soil pH, weed suppression and moisture conservation among mulching materials.

  • Growing plant in potting media without soil is known as Soilless cultivation. This method is used mostly in greenhouse cultivation to increase horticultural commodities production. Peat moss is commonly utilized as potting media substrate because of its characteristic. However, peat moss price is high because of the quantity of peat moss in nature has been decreased. Recently, most of the research is conducted to find the alternative growing medium to cultivate horticulture plant in potting media. Perlite and rice husk ash were mentioned that had a potent as alternative growing media for seasonal plants to increase agriculture production due to the lack of production area. This research aims to determine the growth of in rice husk ash, perlite and peat moss as growing substrates. The method used was the soilless cultivation. The chinese cabbage was planted in the pot with perlite media, rice husk ash media, and peat moss media. The chinese cabbage was measured after 35 days after planting. The result showed that peatmoss was more potentials in chinese cabbage growth performance than rice husk ash and perlite. Peat moss had the significant result of every research parameters such as plant height, plant weight, number of leaves, plant diameter, root length, and root weight. The best alternative for cultivation chinese cabbage without substrate based on this research was peat moss then rice husk ash and perlite.

  • In this study, recovering agent was produced with organic sludge and modified peat moss (MPM) in pilot plant mixer to recover oil contaminated soil, and field test of it was estimated using landfarming method. Oil contaminated soil recovering agent was thought to contain more microorganisms than raw waste sludge and was no problem to come onto the market because there were not any items of specified wastes. According to the results of TPH variation with time, it was observed the initial degradation velocity of oil with produced recovering agent was rapid up to 50% after 4 days, remarkably. Because the microorganisms in the organic sludge discharged from chemical plant already acclimated with oil, therefore, it could be estimated initial degradation velocity of recovering agent might be rapid. It was concluded that the oil contaminated soil recovering agent produced in this study have high marketability because of its two aspects on recycling of wastes and initial rapid degradation capacity.

  • 유망 야생화의 하나인 구절초의 생육에 적합한 배양토를 구명하기 위해 무기재료로서 버미큘라이트, 펄라이트, 암쇄토, 모래, 밭토양을 사용하고 유기물원으로서 피트모스, 부염, 퇴비를 혼합한 배양토를 조성하여 구절초의 생육을 조사한 결과 다음과 같다. 구절초의 생육은 유기물원으로 부엽이 들어간 배양토에서 피트모스나 퇴비를 혼합한 것에 비해 현저히 양호한 것으로 나타났으며 시험 후 배양토의 이화학성 분석 결과 부엽과 피트모스를 사용한 배양토의 화학성은 모든 성분에 있어서 유사한 경향을 나타냈으나 퇴비를 사용한 처리에서는 pH가 ($8.6{\sim}8.9$)로 매우 상승하였고 인산의 함량이 ($237{\sim}1158\;mg/kg$)로 높아져 구절초의 생육을 불량하게 하는 원인이 된 것으로 판단되었다. 피트모스는 화학성분 조사 결과로서는 부엽과 유사한 것으로 나타났으나 양분의 공급 능력에서 부엽에 미치지 못하여 구절초의 생육이 불량하였던 것으로 생각된다. 구절초의 생육에 대한 통계처리 결과를 살펴보면 구절초의 배양토에 있어서 부엽을 유기물원으로 혼합한 상토가 피트모스나 퇴비에 비해 유의성 있는 생육의 증가를 보여 주었다. 부엽을 사용한 VPL, SaVPL, SVPL, UVPL 처리 간에 있어서도 VPL과 UVPL처리가 SaVPL 및 SVPL에 비해 유의성 있는 생육차이를 보였다. 피트모스를 혼합한 처리들과 퇴비를 혼합한 처리들 사이에는 피트모스 처리들이 퇴비에 비해 생육이 양호한 경향을 보였으나 통계적으로는 뚜렷한 경향을 보이지 못하였다.

  • This study was conducted to select environmentally-friendly and low-cost mulching material that could replace soil molding which can be used to restore vegetation in an abandoned coal mine area. To this end, we established 20 experimental plots (4m ${\times}$ 10m in size) on the steep, south west-facing slope of the abandoned coal mine area in Hwangji-Dong, Taebaek City, Gangwon Province in April 2006. We planted two-year-old 1,600 seedlings (at intervals of 0.6m ${\times}$ 0.8m) of drought-resistant tree species including Betula schmidtii, Betula platyphylla var. japonica, Amorpha fruticosa, and Quercus mongolica in the plots. After planting seedlings, mulching was applied by using five different kinds of material such as HWAP (Teracotem), peat moss, straw mats, wood chips, and control (no-mulching) and the effects of different mulching material on the survival rate and growth performance were compared. Three years after planting, the survival rate was the highest in wood chip mulching, followed by straw-mat, peat moss, HWAP, and control. The survival rate was the highest in Quercus mongolica, followed by Betula schmidtii, Betula platyphylla var. japonica, and Amorpha fruticosa. Meanwhile the height growth was the best in Betula platyphylla var. japonica, followed by Betula schmidtii, Quercus mongolica, and Amorpha fruticosa. The height growth of seedlings was the best in HWAP mulching, followed by peat moss, woody chips, straw mat, and control. From an economic point of view, wood chips are considered to be the best mulching material. The results showed that mulching without soil molding and/or mixing applications would be effective for restoring vegetation in an abandoned coal mine areas.

  • Sorption and desorption studies were conducted to evaluate several media as a potential biobarrier for the remediation of groundwater contaminated with hydrophobic organic compounds (HOCs). Pahokee and Bion peats, Devonian Ohio shale, vermicompost, and 50% HDTMA-montmorillonite were used as model sorbents. Sorption and desorption isotherms were determined using the radiolabeled phenanthrene (Phe). Sorption capacity of Phe on several sorbents was in the order Ohio shale > 50% HDTMA-montmorillonite > vermicompost > Pahokee peat. Mineralization kinetics was investigated for Phe-sorbed sorbents using Pseudomonas putida 17484. Among the tested sorbents, active biodegradation of Phe was observed in shale and vermicompost: degradation in shale exhibited little lag time while that in shale showed a significant lag time. Results of this study indicate that sorbents used in this work can be utilized as permeable reactive biobarrier media for the remediation of HOC-contaminated groundwater.

  • To investigate effects of organic matter application on heavy metal uptake of infant rice seeding, the various amount of organic matter(peat and $Bio-com^{(R)}$)was applied on Cd or Cu treated nursery bed soil. No growth difference was observed up to 20mg/kg of Cu treatment. Above 20mg/kg of Cu treatment, the seeding height and top dry weight were decreased but the Cu uptake by seeding was increased with increasing Cu treatment level. The mat formation was poor above 20mg/kg of Cu treatment, however, the seeding peat application level. All peat treatment resulted better mat formation than control. The seeding height and top dry increasing Cd treatment level. The mat formation was not effected by either Cd treatment level or organic matter sources. The effect of peat and $Bio-com{(R)}$ application on Cd uptake by infant rice seeding was not observed at all Cd treatments level.
