Soils of the world hold a key to climate solution and sustainable agriculture. Our happiness, our future and our sustainability are rooted into this loose top layer of the Earth, we call soil. Soil is more than it has been understood as so far. It is the basis of our existence. It is the basis of our survival. It is the basis of our sustainability, and it is the very basis of the whole story of life on Earth. There is a saying: If you own soil, you own up to sky. With our roots in the soil, we can explore skies. But how much do we understand our soil? An understanding of the soil can be fully realized only when we have an understanding of soil ecology. This is what this edited work precisely attempts to do. Soil Ecology attempts to take the knowledge about our soil ecosystems on new horizon, explaining almost all aspects of the soil so vital for acquiring the processes of sustainability and for building up a strong foundation on which climate system of the Earth depends and which is all-capable to cure all climate-related ills.
