Which farming system uses large fields planted with a single crop year after year?

• A. Subsistence Farming
• B. Cash Crop
• C. Output
• D. Monoculture

Answer: (D)

The key idea here is monoculture, a farming approach where a single crop is grown on a large area year after year. This fits the description of large fields dedicated to one crop repeatedly, allowing farmers to specialize machinery, planting and harvesting schedules, and inputs for that crop. Monoculture can bring high yields and efficiency because everything is tuned to one plant’s needs, but it also makes the land more vulnerable to pests, diseases, and soil nutrient depletion, relying more on external inputs like fertilizers and pesticides.

Subsistence farming involves small-scale farming aimed at feeding the farmer’s family, often with a mix of crops and livestock rather than one single crop on large fields. A cash crop refers to crops grown primarily for sale, which could be grown on larger fields but isn’t defined by planting only one crop year after year. Output isn’t a farming system itself.
