An agricultural production process which uses more machinery relative to labour is referred to as
Answer Details
In economics, the term factor intensity describes which factor of production is used in the greatest proportion relative to others. When an agricultural production process uses more machinery relative to labour, it is described as capital intensive farming.
Capital, in economics, refers to man-made aids to production - machinery, equipment, tools, irrigation systems, storage facilities, and other physical assets used in the production process. Capital intensive farming relies heavily on these inputs rather than on manual human labour. Examples include using tractors instead of hand-held hoes, combine harvesters instead of manual cutting, and automated irrigation systems instead of hand-watering.
The other options describe different concepts:
Land intensive farming would emphasize the use of large tracts of land relative to other factors.
Large scale farming refers to the size of the farming operation, not specifically the ratio of machinery to labour.
Commercial farming refers to farming for profit and sale rather than subsistence, regardless of how mechanized it is.
The specific emphasis on machinery relative to labour is the hallmark of capital intensive production.
