The soil moisture has an important effect on growth and development of highbush blueberry (HB), mainly because the root system, devoid of root hairs, is superficial. Moreover, the texture and organic matter content of Korean soil is different from the main producing counties, such as USA and Canada. To facilitate the growth and development of HB and long-term maintenance of productivity, the research related to soil moisture condition in Korea should be the priority. This study was performed to investigate the growth properties of the HB in various soil moisture conditions in order to determine the irrigation trigger point and optimum soil water potential. The texture of soil used in this experiment was loam. For the experiments, the soil was mixed with peatmoss at a rates 30% (v/v). Irrigation was scheduled at -3, -4, -5, -8, -15 and -22 kPa soil water potential then investigated leaf macronutrient, bush growth, and fruit properties. The leaf K content of HB showed the same trend in the soil water potential, but Leaf P and Mg content was highest in -5 and -22 kPa, respectively. The productivity and growth amount of HB showed the peak at the range of -4~-8 kPa as normal distribution pattern, and greatly decreased at above -15 kPa. Total dry weight and Cane diameter were highest at -4 kPa, plant width, fruit weight and yield were highest at -5 kPa, and plant height, cane number and shoot tension were highest at -8 kPa. Soluble solids content showed same trend in the soil water potential, but titratable acidity, anthocyanins and total polyphenols were not significantly different. Therefore, the optimal soil water potential for the development and a maximum production of HB were a range of -4~-8 kPa, and the recommended ideal irrigation trigger point was within -15 kPa.

This study was conducted to examine the impacts of different soil water potentials on environmental soil properties related to the moisture injury of Korean raspberry (Rubus coreanus Miq.). Soil water potential in the plastic film house plots was differentiated from -5 to -40 kPa. Soils in the plots contained 5.6% of plant available water. Increasing soil water contents based on the changes in water potential increased soil pH and exchangeable
content and decreased exchangeable
and total N contents. It also declined soil organic matter content at 9 days after water treatments. Relationship between water potential and soil water content was given as an exponential equation, y = 96.534 - 20.28In(x). In particular, when the water potential was higher than -20 kPa (27.5% of soil moisture content), it decreased chlorophyll content in the raspberry leaves, inhibited N uptake by the plant, and increased phosphorus content with increasing days after water treatment. Also, as the 7 days after water treatment at higher than -20 kPa of water potential, the root activity of the plant was significantly decreased, and trunk (top)/root (T/R) ratio of the plant markedly declined until 9 days after water supply. Carbohydrate contents in the raspberry plant leaves and roots at dormant stage were the lowest at -5 and -10 kPa of water potential plots, and it may cause winter injury to the plant.

Rice production depended on the weed control. The purpose of this study was conducted to evaluate the influence of tillage with chemical amendments + 5 cm flooded, no-tillage without Chinese milk vetch + 5 cm flooded (NTNT 5 cm), no-tillage amended with Chinese milk vetch + 5 cm flooded (NTCM 5 cm), and no-tillage amended with Chinese milk vetch + 10 cm flooded (NTCM 10 cm) on weed occurrence and yield of rice in paddy. Triplicate experimental plots were laid out in a randomized complete block design and compared by employing least significant difference. The dry weights of weeds in NTCM 5 cm and NTCM 10 cm were 11% and 4% level of NTNT 5 cm (p<0.05) and were 3.2 times and 1.2 times more than in conventional tillage system. In addition, the Aneilema keisak and Ludwigia prostrata were significantly increased in NTNT 5 cm (p<0.05). The yield of rice grain in NTCM 10 cm was 2.6 times more than in NTNT 5 cm and was 89% level of conventional tillage system. Our findings suggest that NTCM 10 cm should be enhance of weed control as well as improving of yield of rice in paddy.

Green manure crops are primarily used to reduce the application of chemical fertilizers. In this study, a two-year field experiment was conducted to evaluate the effects of green manure hairy vetch on rice growth and saving of irrigation water. This experiment was conducted at Sinheung series (fine loamy, mixed, nonacid, mesic family of Fluvaquentic Endoaquepts) from 2008 to 2009 at the National Institute of Crop Science (NICS), RDA, Suwon, Gyeonggi province, Korea. Hairy vetch as a green manure crop was incorporated in soil for rice cultivation. Chemical fertilizers had not been applied to hairy vetch plot. Treatments included once irrigation (OI) per week and conventional irrigation (CI). In 2008, the water use efficiency of OI increased by 46% compared to CI by hairy vetch application during rice cultivation season (water treatments were started 38 days after rice transplanting). In 2009, the water use efficiency of OI increased by 61.3% compared to CI by hairy vetch application during rice cultivation season (water treatments were started 30 days after rice transplanting). Soil physical properties such as bulk density, soil porosity ratio and glomalin contents were improved by the incorporation of hairy vetch. The rice yield of OI water management was not significantly different from those of CI water management by hairy vetch application both years. These results suggest that the OI water management with hairy vetch incorporated in soil for rice cultivation can be used in rice fields to reduce the amount of irrigation water and chemical fertilizer.

RDA has been conducting soil survey for farmland all over the korean countries (1964-1999), including small islands and areas of the civilian passage restriction line (2000-present). We conducted a soil survey in Dokdo and Ulreungdo islands and found a new soil series "Dokdo" in Dokdo island. Soil properties of Dokdo were similar to those of Ulreungdo. Representative profiles of Dokdo soil was located at the south 20m of Daehan peak on Seodo (longitude
14'35"), Dokdo. The soil series "Dokdo" was interpreted as the soils were derived from trachyandesite, trachyte, rhyolite, and tuff. The soil properties of Dokdo series were classified as different ones from Korean soil series previously. The soil depth of Dokdo series was very shallow (0-20cm) and soil layer was consisted of very dark brown (10YR 2/2) rocky sandy loam and dark brown (7.5YR 3/2) gravelly silt loam in AC layer. The soils of Dokdo displayed characteristics of a mesic temperature regime, similar as Ulreungdo soils, which were classified as coarse loamy, mesic family of Lithic Udorthents. The total area of Dokdo soil was 18.7 ha, containing Dongdo (7.3 ha), Seodo (8.9 ha), and the others (2.6 ha). The area of Dokdo series in Dokdo was 10.47 ha (Dongdo 4.13 ha, Seodo 6.34 ha) and 808.56 ha in Ulreungdo, where the total soil area was 7,256 ha.

This study was conducted to evaluate fertigation effects of pig slurry (PS) and chemical fertilizer (CF) in cucumber by investigating the growth and yield, nutrient content and uptake, nutrient use efficiency, and soil characteristics in greenhouse cultivation. The cropping patterns of cucumber were semi-forcing culture and retarding culture, and the experiment involves four treatments: No fertilizer (NF),
of N application by slurry composting biofiltration liquefied fertilizer (SCBLF), and
of N treatment by chemical fertilizer. The difference on the plant height of cucumber between SCBLF and CF treatments was no significant, but fresh weight and dry weight of stem and root were higher in
SCBLF treatment. The Ca content of the leaf was lower in the treatments of SCBLF and the K content of the root was lower in the
CF treatment. The Ca content of the stem was lowest in the
CF treatment and the mineral content of the fruit showed no significant difference. In case of semi-forcing culture, the gross yield was lower in the
CF treatment and the yield of unmarketable fruit was lower in the SCBLF treatments. The nutrient use efficiency of cucumber is as follows: K (8.3 ~ 30.9%), N (4.2 ~ 13.0%), P (1.9 ~ 2.0%). The SCBLF treatments showed higher figure in the soil pH than that of the CF treatment, while EC and the content of
-N were higher in the CF treatment than the former. The content of exchangeable K was higher in the plot treated with
SCBLF, and there were no significant differences in the content of Ca and Mg between the treatments. In conclusion, it is suggested that the application of liquefied manure made from pig slurry may be able to replace the use of chemical fertilizer in nitrogen and potassium.

This study was conducted to find the physico-chemical properties and the amino acid content of the pigs hoof hydrolysate, keratin protein and to investigate its fertilizer effect on the growth of crops. The keratin proteins such as pigs hoof were alkali-hydrolyzed to produce the hydrolysates. The chemical properties of the hydrolysate of pigs hoof was 6~7 of pH and
of EC. Total amino acid contents released from the pigs hoof were 10.18%, respectively. The pot experiment was carried out for the cultivation of lettuce. The treatment design of these pot cultivation was composed of Control (compost + NPK), PHH-0.5, PHH-1.0, PHH-2.0 (
; 1,000 ; 500 diluted solution of pig hoof hydrolysate). After lettuce cultivation, the pH values in all treatment soils were decreased than those in initial soils, and the exchangeable cation value was higher than that of control. In all PHH treatments, lettuce growth was better in the leaf length by 6~16% and the leaf width by 4~15% than in control. Therefore, the PHH solutions manufactured by hydrolysis process had plenty of amino acids, and among them PHH had the most abundant nutrients and amino acids with highest growth and yield effect on lettuce.

Fifteen clones of poplars, 2 clones of willows, and yellow poplar were used to evaluate the effects of 5 treatments such as SCBLF (slurry composting and biofiltration liquid fertilizer), general slurry liquid fertilizer, chemical fertilizer, groundwater, and control (no treatment) on vitality, growth performance, and biomass production. Five cuttings for each tree species were planted in 3 replications. After planting cuttings, a coppice was induced by cutting off stems at 10cm above the ground. Data were collected for first growing season and trees were harvested at the end of October. Maximum mortality rate i.e. 96% was recorded in the cuttings treated with groundwater and minimum 92% with control (no treatment). In all tree species, sprouting of stump was not differ significantly among the treatments. Total nitrogen concentrations of leaves and stump sprouts were higher in the treatment of SCBLF than the control, 26.6% and 22.9%, respectively. Biomass production was highest in the stumps treated with chemical fertilizer,
, and lowest in control (

In order to estimate the inorganic nutrient content in cucumber leaves at respective growth stages under greenhouse conditions, we investigated five cucumber farms practicing a forcing cultivation system with nine-month growth period and another five cucumber farms practicing a semiforcing cultivation system with six-month growth period. The cucumber yield in forcing and semiforcing cultivation systems amounted to 14.8 ton
and 10.7 ton
, respectively. Soils between two different cultivation systems showed no significant differences in pH, organic matter contents and exchangeable cation contents during early growth stage, whereas EC,
-N and available
contents were higher in soils of semiforcing cultivation systems. Suitable soil temperature was well provided by forcing cultivation. The highest NPK contents in leaves were observed in 60~80 days after planting for forcing systems and in 100 days after planting for semiforcing systems. Thereby forcing cultivation systems showed somewhat higher NPK contents. Ca and Mg contents in cucumber leaves did not significantly change during the growth period in forcing systems, while semiforcing systems showed the highest contents of Ca and Mg in 80~100 days after planting. Fe, Mn and Zn contents in leaves also did not significantly change during the growth period, whereas Mn contents were slightly higher in forcing systems due to lower soil pH. B contents in leaves were higher in semiforcing systems because of higher available B contents in soil.

Applications of green manures generally improve the soil quality in rice paddy in part through restructuring of soil microbial communities. To determine how different green manures affect soil microbial communities during the early stages of rice growth, fatty acid methyl ester (FAME) profiles were used to the effects of different management practices: 1) conventional farming (CF), 2) no-treatment (NT), 3) Chinese milk vetch (CMV), 4) green barley (GB), and 5) triticale in paddy field. With applications of green manures, soil organic matter was significantly higher than CF, while soil Na concentration was significantly lower compared with CF (p<0.05). Total soil microbial biomass of CMV was higher (p<0.05) than NF by approximately 31%. The highest ratio of monounsaturated fatty acid to saturated fatty acid was found in the GB plot, followed by CMV and triticale compared with CF (p<0.05), possibly indicating that microbial stress was less in GB and CMV plots. Populations of Gram-negative bacteria and arbuscular mycorrhizal fungi also were significantly higher green manures than CF (p<0.05). Our findings suggest that GB should be considered as optimum green manure for enhancing soil microbial community at an early growing stage in paddy field.

An nematophagous fungi Arthrobotrys thaumasia Nema-1 and Pseudomonas putida C-5, which degrade the collagen and gelatin, was isolated from controlled horticultural soils in Seonnam-myun, Sungju-gun, Kyungpook and Woosung-myun, Gongju-shi, Chungnam to develop biological nematode pesticide. When
of A. thaumasia Nema-1 culture was treated to Meloidogyne incognita, the nematicidal activity resulted in 55% at 72 hours after treatment. While the nematicidal activity increased to 65% by treating the culture mixture of
Nema-1 and P. putida C-5 after 72 hours. Furthermore, the nematicidal activity of the mixture containing cinnamon extract
of Nema-1 and C-5 culture was elevated to 89% at 72 hours after treatment, comparing to the result showed 17% and 57% of the nematicidal activity, respectively by the treatment of chemical nemato pesticide Fosthiazate
and neem oil
. These results suggested that the mixture of microorganisms and plant extract were more effective biological nematicide than the case of only microorganism or plant extract for nematode control.

Soil microbial diversity was responsible for a strong effect on the chemical properties of orchard soils. This study evaluated a relationship between soil chemical properties and soil microbial diversities at 25 sites in orchard soils in Gyeongnam Province. The average nutrients in the orchard soils were 2.6 times for available phosphorous, 2.3 times for exchangeable potassium and 1.3 times for exchangeable calcium higher compared to recommend concentrations in the orchard soils. Contents of available phosphorous and organic matter in the inclined piedmont soils were higher than those in the other topographical soils (p<0.05). Populations of fungi and fluorescence Pseudomonas sp. in the silt loam soils were significantly higher than those in the sandy loam soils (p<0.05). In principal component analysis of chemical properties and microbial populations in the upland soils, our findings suggested that population of bacteria should be considered as potential factor responsible for the clear orchard soils differentiation. The soil organic matter was significantly negative correlation with population of bacteria whereas was positive correlation with population of fungi in orchard soils.

Soil management for environment-friendly agriculture depends on the effects of soil microbial activities and soil fertility. To improve soil health for the upland crops, this study evaluated a relationship between soil chemical properties and soil microbial diversities at 25 sites in upland soils in Gyeongnam Province. The average nutrients in the upland soils were 1.7 times for available phosphorous, 1.4 times for exchangeable potassium and 1.5 times for exchangeable calcium higher compared to recommend concentrations in the upland soils. We found a significant positive correlation between the soil organic matter and the soil microbial biomass C (p<0.01). Contents of organic matter and dehydrogenase in the inclined piedmont soils were significantly higher than those in the other topographical soils (p<0.05). In addition, concentrations of organic matter and microbial biomass C in the loam soils were significantly higher than in the silt loam soils (p<0.05). In principal component analyses of chemical properties and microbial populations in the upland soils, our findings suggested that available phosphorous should be considered as potential factor responsible for the clear upland soils differentiation. The soil organic matter was positive correlation with Bacillus sp. and fungi, whereas soil pH was also positive correlation with Pseudomonas sp. in upland soils.

For the environmental friendly soil management on the cultivation of crops in the greenhouse, organic materials, such as the by product-fertilizer derived from livestock manure, rice straw, mushroom media, rice hulls, wood sawdust, and cocopeat, were used as carbon sources adjusting the ratio of carbon to nitrogen to 10, 20, and 30 based on the inorganic soil N. In each C/N ratio of greenhouse soil, watermelon was cultivated in the greenhouse as crop for experiment for the spring and summer of the year and the experimental results were summarized as follows. The concentration of T-C in the organic materials applied were between
, In the C/N ratio of 10, using watermelon as the crop cultivated during the second half of the year in the greenhouse soil, the
-N and EC were reduced by 21 to 37%, and 26 to 33%, respectively, except the by product-fertilizer from livestock manure, compared to the soil
-N and EC used in the experiment. After the watermelon was cultivated in soils that C/N ratios were controlled as 10, 20, and 30 with wood sawdust adding as carbon sources in the three soils with the different EC values, EC values of the soils were reduced by 33, 42, and 39%, respectively, compared to the soil EC used in the experiment. The weight of watermelon was 10.1-13.4 kg per one unit, and, of the three soils with different EC values. In the soils with three different EC values controlled at C/N ratio of 20, the weight of watermelon was good. The degree of sugar of watermelon were 11.8 to 12.3 Brix, which means that the difference between the treatments was not significant. In conclusion, the C/N ratio of 20 controlled by the proper supply of organic materials according to the representative EC values shown in the greenhouse soils was optimal condition enough to maintain the soil management for the organic culture with the proper nutrient cycling.

Currently among the several methods to estimate an environmental impact of products, Life Cycle Assessment (LCA) technique is mostly used. The Ministry of Environment has been performed the carbon footprint labelling to give the carbon record of product by using this method. But the calculation of carbon footprint in primary agricultural product which is raw material of the processed food cannot be made because there is lack of methodology and LCI DB at agriculture sector. Therefore, LCA carried out to estimate carbon footprint, and established LCI DB for complex fertilizers (21-17-17 1 kg, 17-21-17 1 kg, 15-15-15 1 kg, Unspecified 1 kg) in the production system. The result of LCI DB analysis focussed on the GHG, and it was observed that the values of carbon footprint were
for 15-15-15 and
for Unspecified. For the analysis of LCIA (Life Cycle Impact Assessment) on complex fertilizers in the production system, the carbon footprint from pre-manufacturing phase is contributed to 98.96%, 98.81%, 98.88% and 99.30% on each complex fertilizer with 21-17-17, 17-21-17, 15-15-15, and Unspecified, respectively. These results will be used in basic data for estimation of agricultural greenhouse gas emissions.

Boknae Bio-park is a free water surface constructed wetlands to remove non-point source pollution. Boknae Bio-park constructed wetlands (CWs) consist of forebay, wetlands (
wetlands), and micropool. The concentrations of BOD, SS, T-N and T-P in inflow were 1.87-4.23, 5.2-24.0, 4.94-15.59 and
in Boknae Bio-park CWs from April to December in 2008, respectively. The removal rates of BOD, SS, T-N and T-P in Boknae Bio-park CWs were 26, 43, 62 and 83%, respectively. The removal rates of BOD and SS in the spring and summer were higher than those in other seasons. The removal rates of T-N and T-P on spring were slightly higher than those in other seasons. The amounts of pollutants removal in Boknae Bio-park CWs were higher in the order of forebay > wetlands > micropool for BOD, wetlands > forebay > micropool for SS and wetlands > forebay > micropool for T-N. The amount of T-P removal was not significant different in all areas.

To obtain optimum configuration method and livestock wastewater loading in small-scale livestock wastewater apparatus by natural purification method for treating livestock wastewater, the small-scale livestock wastewater apparatuses were constructed with 9 kinds of combined systems such as aerobic bed (ae)-anaerobic bed (an), ae-ae, ae-anoxic bed (ox), an-an, an-ae, an-ox, ox-ae, ox-an and ox-ox livestock wastewater treatment apparatuses. Under different configuration methods, the removal rate of COD in Ae-Ae and Ae-An livestock wastewater treatment apparatus was higher than that in other configuration methods. The removal rate of T-N in Ae-An livestock wastewater treatment apparatus was higher than that in other configuration methods. Removal rates of SS and T-P were not different regardless of configureation methods in small-scale livestock wastewater treatment apparatus. Under different livestock wastewater loading, the removal rates of pollutants were higher in the order of
. Therefore, optimum configuration method was Ae-An livestock wastewater treatment apparatus, and optimum livestock wastewater loding was
in small-scale livestock wastewater treatment apparatus.

In order to develop livestock wastewater treatment technology by natural purification method, the optimum filter media in small-scale livestock wastewater treatment apparatus for treating livestock wastewater were studied. Removal rates of pollutants under different filter media were in the other of coarse sand
broken stone > zeolite > calcite for COD, zeolite >> broken stone
calcite for T-N, and calcite > coarse sand
zeolite for T-P. Based on the above results, the optimum filter media was coarse sand in small-scale livestock wastewater treatment apparatus. To meet acceptable effluent quality standard for livestock wastewater and to improve T-N and T-P removal efficiencies, removal efficiencies of pollutants in small-scale livestock wastewater treatment apparatus with mixed filter media were studied. The removal rates of COD, SS, T-N and T-P in effluent were 84, 94, 65 and 98% in small-scale livestock wastewater treatment apparatus with mixed filter media, respectively. For increasing the T-N and T-P removals in small-scale livestock wastewater treatment apparatus, the mixed filter media are recommended.

This survey was conducted to promote the environment-friendly use and recycling of livestock feces by obtaining information about the current state of livestock feces composts manufactured in Gyeonggi Province. Therefore, some aspects of quality and manufacturing techniques of livestock feces composts (LFCs) were examined especially in relation to the LFCs quality standard (LQS). By surveying the 70 composting plants in Gyeonggi Province, the total commercial production of LFCs in 2008 was estimated to be about
and they were manufactured mainly by using both mechanical mixer and bottom air blower. LFCs were composed mainly of chicken feces 29.2%, pig+chicken feces 23.1%, pig feces 20.0%, livestock feces+oil cake 12.3%, pig+chicken+cattle feces 10.8% and pig+cattle feces 4.6%. On the basis of the current official standard which was revised on March 2010, 11 composts out of surveyed 76 ones did not meet the LQS due to inadequate content of water (5), OM/N (1), NaCl (2) and Zn (3). The satisfaction rate to LQS by manufacturers was 100% in the composts produced by farmer's cooperative societies, 80.7% by civil factories, and 44.4% by farming guilds, respectively. The OM/N declined by adding chicken feces and oil cake, while Ca content was increased by the addition of chicken feces and NaCl was increased by adding cattle feces.

Acid drainage generated by pyrite oxidation has caused the acidification of soil and surface water, the heavy metal contamination and the corrosion of structures in abandoned mine and construction sites. The applicability of Na-acetate (Na-OAc) buffer and/or Na-silicate solution was tested for suppressing pyrite oxidation by reacting pyrite containing rock and treating solution and by analyzing solution chemistry after the reaction. A finely ground Mesozoic andesite containing 10.99% of pyrite and four types of reacting solutions were used in the applicability test: 1)
and Na-silicate, 3)
and 0.01M Na-OAc buffer at pH 6.0, and 4)
, Na-silicate and 0.01M Na-OAc buffer at pH 6.0. The pH in the solution after the reaction with the andesite sample and the solutions was decreased with increasing the initial
concentration but the concentrations of Fe and
were increased 10 - 20 times. However, the pH of the solution after the reaction increased and the concentrations of Fe and
decreased in the presence of Na-acetate buffer and with increasing Na-silicate concentration at the same
concentration. The solution chemistry indicates that Na-OAc buffer and Na-silicate suppress the oxidation of pyrite due to the formation of Fe-hydroxide and Fe-silicate complex and their coating on the pyrite surface. The effect of Na-OAc buffer and Na-silicate on reduction of pyrite oxidation was also confirmed with the surface examination of pyrite using scanning electron microscopy (SEM). The result of this study implies that the treatment of pyrite containing material with the Na-OAc buffer and Na-silicate solution reduces the generation of acid drainage.

A study of different levels of Nutrition Elements and the chemical properties of the soil was conducted to determine the yield performance of potato. Application of sulfur, potassium, and Magnesium significantly affected final height, dry matter content, and crispiness of potato. The final pH, organo-nitrogen, phosphorus, potassium, and magnesium content in the soil were significantly affected by S-K-Mg application.

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.

Ammonium- and potassium-loaded zeolite (NK-Z) and other four kinds of environmental friendly fertilizers/agents were applied to characterize their effectiveness on garlic (Allium sativum L.) growth and soil amelioration. Selenium dioxide (
) and germanium dioxide (
) liquid treatments significantly increased selenium (Se) and germanium (Ge) contents in garlic stems, garlic cloves and clove peels. In soil treated with ZBFC, Se contents in garlic stems, cloves, and clove peels was 13.89-, 12.79-, and 10.96-fold higher, respectively, than in the controls. The inorganic contents of plants grown in soil treated with functional strengthened fertilizers were also higher than in plants grown in control soil. Soil treated with arbuscular mycorrhizal fungi (AMF) agents exhibited significantly greater spore density and root colonization rate than in untreated soil. The density of chitinolytic microorganisms in soil treated with colloidal chitin was also significantly higher than in untreated soil. The cation exchange capacities (CEC) in ZAFC-, ZBFC-, and ZBF-treated soils was 16.05%, 8.95%, and 8.80% higher than in control soil 28 weeks after sowing.

Biopiles which offer the potential for cost-effective treatment of contaminated soils are above-ground, engineered systems that use oxygen to stimulate the growth and reproduction of aerobic bacteria for degradation of the petroleum constituents adsorbed to soil in excavated soils. This technology involves heaping contaminated soils into piles and stimulating aerobic microbial activity within the soils through the aeration and/or addition of minerals, nutrients, and moisture. Inside the biopile, microbially mediated reactions by blowing or extracting air through the pipes can enhance degradation of the organic contaminants. The influence of a aeration system on the biopile performance was investigated. Air pressure made to compare the efficiency of suction in the pipes showed that there were slightly significant difference between the two piles in the total amount of TPH biodegradation. The normalised degradation rate was, however, considerably higher in the aeration system than in the normal system without aeration, suggesting that the vertical venting method may have improved the efficiency of the biological reactions in the pile.
