What factor significantly aided agricultural production at the turn of the 20th century?

Industrialized agriculture significantly aided agricultural production at the turn of the 20th century due to the introduction of advanced machinery, synthetic fertilizers, and chemical pesticides. These developments allowed farmers to increase crop yields and manage larger plots of land more efficiently. The mechanization of farming tools such as tractors and harvesters enabled quicker planting and harvesting, which drastically reduced the labor force required for agricultural tasks. Additionally, the use of synthetic fertilizers contributed to soil fertility, resulting in higher productivity per acre. The overall shift towards industrial practices marked a pivotal transition in farming, supporting the growing population and changing food demands of the time.
