Rotating crops is an agricultural practice where different types of crops are planted in the same area in sequential seasons. This technique can enhance soil health, improve nutrient cycling, and reduce pest and disease pressure. By alternating crops, farmers can help maintain or increase soil fertility since different plants have varying nutrient requirements and contributions. For example, legumes, which can fix nitrogen in the soil, are often rotated with nitrogen-consuming crops like corn. This cycle promotes biodiversity in farming systems and can lead to better yields over time.

In contrast, the other options relate to different concepts and do not pertain to agricultural practices. Saliva is a bodily fluid involved in digestion, runoff refers to the flow of water (often contaminated) from land into bodies of water, and rust is a fungal disease that affects certain crops. None of these options describe a method related to crop management or agricultural cycles.
