Nonggajipseong (Compilation for Farmers) was compiled by Sin Sok (1600-1661), a civil official and agriculturist of the mid-Joseon Dynasty. It is a combination of improved versions of several books intended for farmers, including Nongsajikseol (Straight Talks on Farming), Quannongwen (Proclamations for Encouraging Agriculture) by Zhu Xi, Geumyangjamnok (Notes on Farming in Geumcheon County) by Kang Hui-an, and Guhwangchwaryo (Essentials for Relieving Famine). This book is a valuable material on the development of farming methods.
