Internal Combustion Engine
Pre-World War II - The first 40 years of the 20th century saw simultaneous advances in biochemistry and engineering that rapidly and profoundly changed farming. The introduction of the gasoline-powered internal combustion engine ushered in the era of the tractor, and made possible hundreds of mechanized farm implements. Research in plant breeding led to the commercialization of hybrid seed.And a new manufacturing process made nitrogen fertilizer - first synthesized in the mid-1800s - affordably abundant. These factors changed the labor equation: there were some 600 tractors in the US around 1910, and over 3,000,000 by 1950; in 1900, it took one farmer to feed 2.5 people, where currently the ratio is 1 to well over 100.Fields grew bigger and cropping more specialized to make more efficientuse of machinery.
