Question

How is it that crop yields increased in the decades after world war ii despite the number of farms decreasing?

Answer 1

Better farming technology, techniques, and genetically modified crops!

Answer 2

Crop yields in the United States increased in the decades after World War II despite the fact that the number of farms decreased. This was due mainly to the introduction of new technology that allowed the remaining farms and farmers to be much more productive.

These advances in technology were born out of an interest in research. Agricultural research increased during the 1940s, and this led to a revolution in agricultural technology. The technology allowed farmers to produce equal yields with less people involved.
