Final answer:
Extensive farming describes the agriculture method where large land areas are cultivated using machinery instead of manual labor, as opposed to intensive agriculture, which uses labor-intensive methods on the same land repeatedly.
Step-by-step explanation:
The term used to describe agriculture where large parcels of land are cultivated using machinery rather than manual labor is a. extensive farming. In extensive farming, multiple plots are managed over a wide area, leveraging machinery and technology to mass-produce commodities and potentially reduce the demand for costly farm labor. This is distinct from intensive agriculture, which involves repeated and labor-intensive methods such as plowing, terracing, and irrigation on the same plot of land to enhance productivity and yield.
