How was farming different in the 1920s compared to now?

Farming in the 1920s relied heavily on manual labor and horse-drawn equipment, with farmers often using traditional methods and crop rotation for sustenance. In contrast, modern farming employs advanced technology such as GPS-guided machinery, biotechnology, and precision agriculture, resulting in higher efficiency and yields. Additionally, the scale of farming has expanded, with many operations now being industrialized and focusing on monoculture practices. These changes have transformed farming from a mostly local, labor-intensive endeavor to a highly mechanized and globalized industry.
