In what category are Corn-grain and Soybeans classified?

Corn-grain and soybeans are classified as coarse grains. This classification is based on the characteristics of the plants and how they are utilized in agriculture. Coarse grains typically refer to the grains produced by plants in the Poaceae family that have a relatively large seed size compared to other grains like wheat or rice.

Corn (maize) is one of the most widely cultivated coarse grains due to its high energy value and use in both human consumption and animal feed. Soybeans, while a leguminous crop used primarily for their protein-rich seeds, are often grouped with coarse grains in agricultural discussions because they share similar agronomic traits and are frequently grown in rotation with them for improved soil health and pest control.

Small grains usually refer to cereal crops like wheat, oats, and barley, which are distinctly different from corn and soybeans in both plant structure and usage. Leguminous crops generally include those which have the ability to fix nitrogen in the soil, such as peas and beans; soybeans do fall under this category as a specific type, but their primary classification for crop insurance and common agricultural practices leans toward being grouped with coarse grains for their production scale and methods. Perennial crops, on the other hand, are those that live for more than two
