House Bill 901, known as the "Tennessee Century Farms Act," aims to recognize and promote the historical significance of family farms in Tennessee that have been operational for over one hundred years. The bill defines a "century farm" as one that consists of at least ten acres, generates a minimum of $1,000 in annual revenue, has remained in the founder's family for at least a century, and is partially owned by a state resident. The bill mandates the establishment of a century farms program by the commissioner of the department of agriculture to highlight these farms' contributions to the state's agriculture and economy.

The commissioner is tasked with operating the program using existing resources, setting qualification criteria, designating a historic preservation center to manage the program, and providing commemorative signs to recognize century farms. These signs will be given at no cost to the farm owners and can be obtained for additional milestones of fifty years of continuous operation. The designated historic preservation center will maintain a database of century farms, collaborate with relevant state departments, and promote public awareness of the importance of these historic farms in Tennessee. The act will take effect upon becoming law.
