Nongsajiksol is a book which Jong Cho (?-1434), a government official and scholar in the period of the feudal Joson dynasty (1392-1910), compiled in 1429 by synthesizing and systematizing the farming methods and experience suited to the climatic and soil conditions of Korea.
The book is relatively small in volume as it contains the farming experience of limited areas.
However, it embraces lots of valuable historical data farmers should know for the cultivation of crops ranging from seed preparation to ploughing, manure preparation and cultivation methods of various cereal crops.
Besides, it deals with various farming tools, manuring methods and the growing methods of such gramineous plants as rice, millet, foxtail millet, barnyard grass, wheat and barley, such leguminous plants as soybean, adzuki and mung bean and such other plants as sesame and buckwheat.
Therefore, the book was reissued several times until the late period of the feudal Joson dynasty to be widely used in farming and contribute to the development of agricultural techniques.
As one of the oldest agricultural books from the Middle Ages of our country, Nongsajiksol is helpful to studying the development of the farming methods and techniques in the period.
