What microorganisms increase soil fertility?
Bacteria increase soil fertility through nutrient recycling such as carbon, nitrogen, sulphur and phosphorus. Bacteria decompose dead organic matter and release simple compounds in the soil, which can be taken up by plants.

What do soil microbes eat?
Almost all soil organisms (except some bacteria) need the same things that we need to live: food, water and oxygen. They eat a carbon-based food source, which provides all their nutrients, including nitrogen and phosphorus.
What is harmful microorganism?
Harmful microorganisms include fungi, bacteria, protozoa, etc. They cause several diseases in human beings, animals, and plants which can even lead to death. The harmful microorganisms not only damage the human body but also the food we eat. Such disease-causing microorganisms are called pathogens.
