12. Agricultural Innovations
The Han Dynasty (206 BCE-220 CE) introduced significant agricultural innovations that enhanced productivity and efficiency. Notably, the development of the three-legged iron seed drill enabled farmers to plant seeds in precise rows, improving crop yields. Additionally, the heavy moldboard iron plow, requiring only one man and two oxen, facilitated the cultivation of larger areas. These advancements laid the foundation for modern agricultural practices in China. (history.com)
