Nowadays liquid manure can no longer be regarded as a waste product, but as a compound fertilizer, which should be used as efficiently as possible, especially on the farm. Additionally, there is the intensified public discussion about environmental issues.
With respect to the ecological effects of the proper application of liquid manure, administrative regulations in the form of guidelines, decrees and ordinances have been established in region. It is questionable though, if such quantifying restrictions bring a reduction of ground water pollution, or if not through these measures new problems will be created, i. e. be temporarily postponed.
Moreover, in this Study, possible Operation and technical Improvement are presented.

In 1992, HyoGo County in Japan itself established a guideline for the environment friendly agriculture and have been propelling the environmentfriendly agriculture as a major agricultural policy together with organic farming.
This study focuses on the evaluation of the “organic farms’ villages” projected by the County among other projects.
The results indicate that the project results in several benefits such as decrease in chemical input use and environmental pollution, and enhancement in farmers’ concerns on safety and environment. On the contrary, it shows that no economic benefits are anticipated in the short run with the organic farming.
Therefore, it is necessary to consider economic incentives for farmers who adopt the organic practices to sustain farmers’ income.

This study attempted to estimating economic value of environmental resource by using the contingent valuation method(CVM), known as one of the tool measuring the economic benefits. To analysis the preservation value of Bongseo Mt., the surveys were conducted for citizens resident in Cheonan city. The sample sizes of the survey were 200 respectively. The survey method adopted facetoface interview method as a mean of correcting useful response. This study considers models for evaluating the willingness to pay(WTP) based on payment card contingent valuation survey data and has attempted to measure goodness of fit for the data obtained from the survey design.
It was estimated that the average WTP of Cheonan citizens for a maintenance and management of Bongseo Mt. was 5,010 won per month and 60,118 won per year. When it is translated by total number of households in Cheonan city, there is the preservation value of approximately 8.8 billion won per year. On the other hand, total expense of development increased about 1.7 times over including application of the preservation value.

This study was carried out to investigate the effects of different plant growth media on the growth of tomato(Lycopersicum esculentum Mill.) seedlings during growth stages. The media were commercial plant growth medium 100%, earthworm cast(that was produced by vermicomposting of food waste and cattle manure) 100%, earthworm cast 50%, vermiculite 50%, earthworm cast 50% ＋ perlite 50%, earthworm cast 40% ＋ vermiculite 30% ＋ perlite 30%. Plant length(㎜), number of leaves, leaf area(㎠), stem diameter(㎜), plant dry mater were greatest till the 2nd week growth stages in the commercial plant growth medium plots, but those were higher in the earthworm cast than those in the other plant growth media at the later stages of this study(p＜0.05). And relative growth rate of biological yield, relative growth rate of shoot and relative growth rate of root were highest in the earthworm cast till the 4th week growth stage.
Therefore it can be implied that there is the possibility of potential utilization of earthworm cast, which was produced by vermicomposting of food waste and cattle manure, as vegetable growth medium.

This study was conducted to established method of culture for Paecilomyces japonica using an egg. Mycelia grew favorably at the temperature of 22~26℃ on eggs. 5.1g of dry matter basis(average 7.2㎝ of longer and 199.6 of numbers) of artificial fruiting bodies were harvested at 60 days after inoculation from one of egg. Commercial fruiting bodies of Paecilomyces japonica from silkworms was used for comparative nutriental contents. Cordycepin contents of fruit bodies of Paecilomyces japonica cultivated on eggs and silkworms were not significantly different. Crude fat contents of fruiting bodies of Paeilomyces japonica cultivated from eggs was significantly higher than from silkworms(P＜0.05). Mn and Cu contents of fruiting bodies of Paecilomyces japonica cultivated from silkworms were significantly higher than from eggs(P＜0.05), but Na, Mg, Fe and Zn contents were significantly higher from eggs(P＜0.05). Glycine, Arginine and Proline contents in the fruiting bodies of Paecilomyces japonica cultivated from silkworms were tend to higher than from eggs, but Serine, cystein, methionine, isoleucine and phenylalanin were tend to higher from eggs. These results were made possible that possible mass production of artificial fruiting bodies of Paecilomyces Japonica cultivated on eggs.

Saved labor cost, energy conservation, reduced soil erosion, and increase of emergence rate would be expected from no-tillage cultivation of corn. Few research has been reported on the notillage effects for waxy corn hybrid. Five waxy corn hybrids were tested under conventional and notillage practices to investigate responses of early growth, plant characters, ear characters, fresh yield, and grain yield. Emergence rates under notillage were lower than under conventional tillage. Plant heights at early growth stages under notillage were higher than those under conventional tillage. Plant height under notillage was higher than that under conventional tillage. There were no differences between conventional tillage and notillage for ear length, number of kernel rows, number of kernels per row, 100 kernels weight, fresh yield, and grain yield. This result indicates that notillage practice might be recommended for practical method for waxy corn production. Days to tasseling and silking, plant height, ear height, ear length, and number of kernels per row were correlated with fresh and grain yields.

The mudfish(Misgurnus anguillicaudatus) raising fed on hens excreta in order to study effects on production of animal feed resource. The raw hens excreta used for 2 years old mudfish diet during the 35 days and water in aquarium for mudfish was never exchanged during experimental period. Eight of 100L of aquarium, eight ㎏ of mudfish and four of female korean native chicken were used this study. This study are divided according to the mudfish fed on commercial mudfish diet in the four of control group and fed on hens excreta in the four treatment group. The chemical composition was compared with commercial mudfish diet and hens excreta. In the both sample, crude protein contents was almost same. The crude fat and crude ash were higher in hens excreta than commercial mudfish diet. The growth performance of mudfish tend to high when fed hens excreta. There were no differences in contents of E. Coli and Salmonella and pH of water in aquariums between the groups. Mortality of mudfish tend to decrease when fed hens excreta. No problem with mudfish health was observed during the experimental period of 35 days.
These results indicated that it is possible to raising mudfish fed on hens excreta only.
