The principle goal of environmentally-friendly agriculture is to maintain and conserve water and agriculture environment including drinking water resources by properly using agricultural materials such as agricultural chemicals, chemical fertilizers, and other agricultural materials according to act 19 of foster law of environmentally-friendly agriculture. To achieve these goals, we have to establish Integrated Nutrient Management(INM) and Integrated Pesticide Management(IPM) which are most important core technologies for environmentally-friendly rice cultivation. However, there are lack of criteria and technology for evaluation category according to soil management and its soil classes to practice an environmentally-friendly agriculture. Therefore, we should eatablish the standards to produce the safe agricultural products based on the soil physical and chemical characteristics which are basic properties of soil to accomplish the principle aims of environmentally-friendly agriculture.

우리나라에서는 농업분야의 경쟁력 강화를 위한 일환으로 임도사업이 전국적으로 실시되고 있으나 임도개설에 따른 토사유출(土砂流出) 및 수질악화(水質惡化) 등의 환경문제가 대두되고 있다. 따라서 임도사업의 역사가 길고 자연환경 등이 우리나라와 유사한 일본에 있어서 임도분야의 연구방향, 임도개설유역의 환경영향평가 방법, 환경친화형(環境親和型) 임도시공(林道施工) 및 연구방법에 대한 자료를 정리하였으므로 앞으로의 합리적(合理的)인 유역관리(流域管理)와 친환경적(親環境的) 임도사업(林道事業)에 유용하게 사용될 것으로 생각된다.

생태계에서 물질 순환에 있어서 교환과 저장의 가장 중요한 역할을 하는 토양은 급격한 농업생태계 내 유해 물질의 증가로 국민건강과 관련한 사회적 문제로 대두되었고 있다. 이러한 토양은 토양의 기본 특성인 생산성과 환경요인이 복합된 토질 (Soil Quality)이라는 개념으로 해석되고 있어 지속적으로 친환경농업을 유지하기 위한 토양 관리지표는 매우 중요하다. 토양은 분포 범위도 다양하고, 토질에 관여하는 여러 환경적 요건의 변화도 다양하므로 토질에 관여되는 각 변수들에 대한 환경 위해성을 고려한 토질 기준 설정이 필요하다. 그리고 친환경 농산물의 생산을 위한 토양 관리 방법과 기준은 여전히 미흡한 실정이므로 토질 개념화의 변수들을 파악하고 이에 따른 토양 관리 방법에 대한 연구가 필요하다.

A review on the technical development and agricultural policy direction for sustainable agriculture has been made to clarify the present conditions of agricultural environment for food production and natural resource conservation and to study prospects and solutions successfully to achieve food safety and environment conservation as the 21st agricultural paradigm. Although great improvement of environmentally sound and resource-conserving techniques, sustainability of Korean agriculture has been damaged by quantitative reduction and quality deterioration of agricultural land resources, insufficient implementation of low-input and organic matter recycling techniques and also improper cropping system. It is concluded that goal of sustainable agriculture can be successfully achieved by further improvement of environmentally friendly techniques, and stronger escalation of national implementation programmes with more financial supports including direct payments for sustainability of agriculture under systematical support and cooperation of AKS (agricultural knowledge system).

This study was initiated to build runoff plots, install soil and water quality monitoring systems and collect background data from the plots and neighboring soils as the 1st year study of a 5 year project to assess soil quality and develop the management practices for environmentally sound agriculture in mountainous soils. Eleven $3{\times}15m$ runoff plots and monitoring systems were installed at a field of National Alpine Agricultural Experiment Station to monitor soil quality and discharge of nonpoint source pollutants. Corn and potato were cultivated under different fertilizer, tillage and residue cover treatments. The soil has a single-layered cluster structure that has a relatively good hydrologic properties and can adsorb a large amount of nutrient. Concentrations of T-N, $NH_4$-N, and $NO_3$-N of surface soil sampled in the winter were relatively high. Runoff quality in the winter and thawing season in the spring was largely dependent on surface freezing, snow accumulation, temperature, surface thawing depth and so on. Runoff during the thawing season caused serious soil erosion but runoff quality during the winter was relatively good. Serious wind erosion from unprotected fields after the fall harvest were obserbed and best management practices to reduce the erosion need to be developed.

The duck-rice forming system is increasingly spread up throughout Korea since 1992. It is discussed the rice field, rice quality, weed and pest management in the duck-rice weeding system compared to conventional farming system. Moreover the optimizing duck population, system management and fertilizer application rate were reported. Energy input and output by duck-rice farming system were carefully compared with those of low input sustainable paddy field and conventional farming paddy field. To find out the environmentally sound function of duck-rice system, the total nitrogen in paddy soil and paddy water, and nitrogen cycle in paddy rice cultivation system were analysed. finally the input and output were calculated, and ecological characteristic were determined in terms of nitrogen balance, labor input, animal input, renewable energy input, turnover of soil organic matter, energy loss, non-renewable indirect and direct energy input. It was concluded duck-rice weeding system could be recommended in terms of net only environmentally sound, but also farmer's income. But there are still some research needs for successful adaption of duck-rice farming to investigate to determine the optimal population of duck in rice paddy field unit, release time of duckling, duck management after release, and strategy for duck marketing and duck processing.

Environment agriculture carried out from 1999 in Daeho reclaimed saline area, located in central east cost of Choongnam Korea, resulted in dramatic reduction of amount of nitrogen fertilizer and application times and amount of pesticides. The ecological status of Daeho reclaimed saline area was considered to still very sound from the results of ecological survey on flora and fauna. However, it was desirable to adapt precision agriculture for production of high eating quality of rice and preservation of Daeho ecosystem. Especially, precise application of nitrogen and phosphorus fertilizer was recommendable for prevention of water pollution in environment rice cultivation by duck or mud snail or crab. The bioefficacy of Scirpus maritimus and Echinochloa crus-galli in paddy field of environment rice cultivation by duck or mud snail or crab in Daeho reclaimed saline area was revealed very low. Therefor, it was concluded that the pre-measures of reduction of natural weed population were necessary for successful environment agriculture. The most desirable and ideal environmentally sound agriculture in Daeho reclaimed saline area was performance of crop rotation, introduction of legume crops and green manure crops, and also, simultaneous management of crop production and animal husbandry for smooth flow of energy cycle within the closed Daeho ecosystem.

A relatively wide range of weed technology concerning sound herbicide development, its formulation exploitation, and application techniques was extensively reviewed in accordance with least inputted sustainable agriculture. Herbicide plays an integral part of farmers' cultural practices in Korean agriculture like rest of world over. Weeds are more obstacle to the adaptation of more sustainable agriculture system. Because weeds dictate most of the crop production practices, weed scientists must become the leaders of collaborative integrated approaches to agriculture systems research. Feasible ways to minimize herbicide input involve the positive introduction of low-rate selective chemistries, innovative formulations, biological herbicides and newly developed application technology. Since herbicide will remain to be a core position in weed management for the foreseeable future, research is needed to optimize herbicide application technology and to minimize their impact on the environment. Public concerns and regulatory pressures on agricultural chemicals are likely to strengthen throughout this decade and coming. Researchers, pesticide manufacturing industries and regulatory authorities have to work together more closely, leading to understand each other better, as well as the needs of our customers and those of society. To be taken extensively, weed control management practices in the future have to be accepted such a way the respective demands of environment, society and economics are entirely matched.

Food is very important for human being. It is not easy for us to enjoy good life because the situation of food is not good in Korea. The self-sufficient food rate is very low and most of food which we take was produced by industrial agriculture. Food of this kind has some problems with respect to the health of consumer, agriculture, environment and community. In order to secure the true food which is safe and environmentally sound, producers, consumers and community have to work together. Producers must engage in environmental agriculture. They must produce the true food and need to know regional consumers. Consumers must pay attention to the regional agriculture and must participate the production of true food. Local government must open farmers' markets for direct marketing between farmers and consumers. NGOs should educate and organize the producers and consumers.
