John is a farmer who wants to keep his soil as productive as possible. which of these actions would him achieve this goal? a. excessive irrigation b. crop rotation c. soil exhaustion d. leaching

The correct answer is B. crop rotation.

Crop rotation refers to the process where a farmer changes the types of products he or she is growing on their fields. Crop rotation helps maintain the balance of different nutrients within the soil (because different crops require different nutrients) and reduces the number of pests on the land by changing the crops and thus the habitat of the pests. Crop rotation thereby encourages soil fertility and would increase production.
