In order to maximize grain storage life and preserve their yield, many farmers choose
to store their grains in silos. Silos are high-capacity commercial or industrial
structures that are used for permanent grain storage. Besides storage, silos also
provide other post-harvest management functions. It is a tall structure or pit on a
farm used for stocking up bulk materials and is used in agriculture for the purpose
of storing grain or fermented feed, known as silage. Silos are more frequently used
for storing bulks of grain, carbon black, coal,
cement, wood chips, sawdust, and food products.
