Why is bacteria in soil critical to its health and fertility? 11.03 Why is bacteria in soil critical to its health and fertility? Because the bacteria support vegetable growth. Because the bacteria fight off diseases that the soil might undertake. Because the bacteria eat all of the carbon that can ruin the plants. Because the bacteria undergoes photosynthesis which helps the life of the soil.
