Soil Biological Fertility - Lynette K. Abbott

. .

Résumé :
This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It demonstrates the interdependence of soil biological fertility with physical and chemical characteristics of soil. The book highlights the enormous diversity of life in soil and the resulting effects that management of land can have on the contribution of this diverse community to soil fertility in an agricultural context. It is becoming more relevant to explore soil biological processes in terms of their contribution to soil fertility.
