Answer:
C An increase in the activity of nitrogen-fixing bacteria
Explanation:
Legumes are crops e.g . Beans and they have root nodules which houses symbiotic nitrogen fixing bacteria. This nitrogen fixing bacteria helps to replace nitrogen lost as a result of previous cultivation back to the soil. Nitrogen is an important element in agriculture as it aids
Photosynthesis and useful in manufacture of protein.This is why legumes are important in crop rotation which helps to restore lost nutrients to the soil.
