Practical Uses

Farmers often divide it into fields for crops or livestock, yielding high productivity—think 40 acres of corn producing over 400,000 pounds annually under ideal conditions. Developers might build 100+ homes if zoned residential, per typical densities. In 2026 real estate trends, such parcels near growing suburbs fetch premiums for self-sustaining homesteads amid rising food costs.

Historical Context
