Agricultural Tools Convenience Theory

Japanese: 農具便利論 - のうぐべんりろん

This book was written by Okura Nagatsune, an agronomist from the end of the Edo period, and is one of his major works along with Koeki Kunisanko. It consists of three volumes and was published in 1822 (Bunsei 5). It provides detailed illustrations of agricultural tools used throughout the country that are considered worthy of widespread use. It covers tools for each task, such as plowing, sowing, weeding, fertilizing, watering, harvesting, and adjustment, but it is particularly detailed about hoes, and gives numerical explanations of the length and width of the blade of each type of hoe, as well as the angle of the blade to the handle, making it the most detailed and practical illustrated guide to farming tools from the Edo period.
