Soil Health and Its Biology

It is well known that, the health of humans is mainly depends on the physical, social and nutrient factors. The health of humans requires safe, proper and sufficient supply of nutrients through the foods. This quality of foods mainly depends on the biology, fertility and quality of soils, in which crops were cultivated. Thus, the biology of soils has direct and/or indirect effects on the health of humans through the exposure to soils and their microorganisms, extract different medicines from soils and deficiency of nutrients through food chain. The biology of soils also has a close relationship with the nutrition of both plants and humans. Therefore, soil quality and its biology is a crucial issue towards sustainable agriculture. Thus, the main purpose of this book chapter is to emphasize the link between soil quality through its biology and human health. The great roles of soils in our life also will be highlighted.
