Soil: its geology and use

It is estimated that at least 72% of the surface of the globe, excluding the area covered by ice, permafrost and fresh water, is covered with soil. In agricultural studies great advances have been made in the investigation of the soil in which crops grow, pedology being now a well- established branc...
