Which of the following is a limitation of a crop rotation over a monoculture system?

Crop rotation can be a beneficial practice for enhancing soil health, pest management, and nutrient cycling. However, a limitation of implementing a crop rotation system compared to a monoculture system lies in the potential need for more equipment. When a farmer shifts from monoculture—growing a single crop annually—to rotation, they may need to diversify their equipment to handle different types of crops. Different crops can require varying planting and harvesting techniques, specific tools for application of fertilizers or pest controls, and distinct machinery configurations. Consequently, this increased demand for multiple types of equipment can lead to higher initial investments and increased operational complexity, which is a noteworthy limitation in adopting crop rotation.

In contrast, a monoculture system can simplify machinery needs, as all operations are tailored to the same crop type year after year, thereby making the farming processes more streamlined and potentially less costly in terms of equipment.
