What term describes the practice of alternating crops on the same piece of land to reduce erosion and control weeds?

• A. Crop rotation
• B. Cover cropping
• C. Intercropping
• D. Vertical farming

Answer: (A)

The practice of alternating crops on the same piece of land is known as crop rotation. This agricultural technique helps improve soil health, reduce pest and weed pressures, and prevent erosion. By planting different crops in a systematic order, farmers can take advantage of specific nutrient requirements and growth patterns of each crop, promoting biodiversity within the soil ecosystem. Crop rotation helps mitigate the risk of soil depletion, as different plants can contribute various nutrients to the soil or utilize different soil layers for their nutrient needs. For instance, a nitrogen-fixing crop like legumes can be followed by a nitrogen-hungry crop like corn, which optimizes soil nutrient levels and enhances overall crop yields. Cover cropping refers specifically to planting crops primarily for soil protection and improvement rather than for harvest, while intercropping involves growing two or more crops in proximity to each other for purposes such as maximizing space and resources. Vertical farming, on the other hand, is focused on growing food in stacked layers, often incorporating controlled-environment agriculture methods to increase yield in limited space. These other methods have their benefits, but they do not fully encapsulate the broader practice and objectives of crop rotation.
