Sannongji 三農紀 "Records of the three country people" is an agricultural treatise written by Zhang Zongfa 張宗法 (1714-1803), courtesy name Shigu 師古, style Weiliaoweng 未了翁, from the district of Shifang 什邡, Sichuan. Zhang never achieved academic merits, but was a literatus engaging in farming. The title of the book refers to the knowledge of the "farmers of old" (laonong 老農), the skills of the cowherd boys (mutong 牧童), and the diligence of the cultivators (gengfu 耕夫).
The first three of a total 24 juan (in the two oldest editions; the others are divided into 10 juan) are dedicated to the weather of the seasons, prognostication, and farming activities in each particular month. Chapter 4 and 5 speak of soil treatment, general cultivation, and irrigation. Fascicle 6 is dedicated to disaster relief. The longest part of the book (ch. 7-18) describe the cultivation of individual plants from grains to legumes, fruits, bamboos, mulberry, tea or sugar cane, but also cover topics like ploughing, fertilization, the processing of fibre, oil, dye, and medical plants. This part is followed by two chapters on domestic animals, including medical care. The book closes with descriptions of farm buildings, tools, customs, and sideline work like food processing and health care.
