What is considered a small grain?

A small grain refers to a category of crops that are typically grown for their edible seeds and are characterized by their small seed size. Wheat is the most recognized example of a small grain, as it is widely cultivated for food products and has significant agricultural importance.

When considering the other options, corn, sorghum, and soybeans are classified differently. Corn is a type of cereal grain but is not categorized as a small grain, primarily due to its larger seed size and growth characteristics. Sorghum, while also a grain that can be used for animal feed and human consumption, is classified primarily as a cereal grain rather than a small grain. Soybeans are classified as legumes, and their cultivation focuses on a different set of agronomic practices. Thus, wheat stands out distinctly as the correct answer when identifying small grains.
