[From Latin praef remarks note that the Green Revolution that helped developing countries in the past is now in a state of fatigue fatigue, in engineering fatigue, in engineering, microscopic cracking of materials, especially metals, after repeated applications of stress. Fissures may be formed within pieces of metal during their manufacture when, while cooling from the molten state, , so that "ever-green" or sustainable approaches are now required. Introductory chapters treat soil system dynamics System dynamics is an approach to understanding the behaviour of complex systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system. at the core of this biological approach. Subsequent chapters address specific agents and processes involved in the soil habitat, integrated methods for enhancing soil fertility fertility: see infertility. fertility Ability of an individual or couple to reproduce through normal sexual activity. About 80% of healthy, fertile women are able to conceive within one year if they have intercourse regularly without contraception. , and related issues (e.g., the effects of climate, economic and political agendas, production trends, and monitoring and modeling systems).
