The definition of a commodity is any natural resource that holds/carries a value in commerce. Agricultural commodities are a type of natural commodity that is planted, grown, and harvested.
Corn, wheat, soybeans, sugarcane, coffee, cotton, rice, cocoa, and lumber are examples of agricultural commodities. Like most other commodities, agricultural commodities are bought/sold through commodity futures.
Commodity futures provide the most efficient method of bringing together producers and consumers/users, bringing liquidity into the markets. Out of all agricultural commodities, corn is the largest produced commodity in the United States. In the United States, commodity futures are traded in the Chicago Board of Trade (CBOT).
