다국어 초록 (Multilingual Abstract)

Plowing the soil has been the first Farming-Techniques that has been mastered and operated by people since the Ancient times of the farming. Among the Oriental Ancient Books, it has been described as the most and important and indispensable element as the Farming-Techniques. People have thought from the ancient times that farming is the holy work that linked universal spirit between earth and the sky. Plowing is the farming process to require lots of labor, but the effect had been infinitely various depending on the method, timing, crops and soil. According to the Korean Ancient Agricultural Books, plowing has been examined and developed in the way that people had worked less and less as far as possible through the farming effect. As the example of crops such as bean, it has been concluded that less work plowing or the level depending on stubble for the front line crops and the almost no-tillage are proper and no problem. Moreover it has been proved that plowing has no other additional meaning with only the work in order to seed after plowing preexisting weeds out. After establishing th techniques to weed efficiently with herbicide, for the crops such as corn and bean, the method of cultivation as the minimum tillage or no-tillage has been started as the systematic cultivation way. This logical theory has been proved based on my experimental research of the no-tillage techniques. In the ancient plowing techniques, the minimum possibility of the efforts has been acquired through accumulating this farming techniques development process.
