The Evolution of American Farm Silos

The conspicuous silo on American farmsteads is the result of an evolving process to store ensilage effectively. From merely indoor stone-lined pits in the ground and exterior wooden rectangular and circular silos of the past, today's silos include the highly mechanical fiberglass and metal (Harvestore) structures. Ensilage has become an important aspect of agriculture, especially in the northeastern quarter of the United States and adjacent parts of Canada. The silo reflects the ongoing changes in agricultural production and in the American farmstead.
