Soil is a vitally important resource that supports approximately 90 % of all human food, livestock feed, fiber and fuel requirements. Furthermore, soil is increasingly recognized as an important sink for atmospheric CO2 that can help offset greenhouse gas emissions due to the burning of fossil fuels. Unfortunately, soil is not renewable and readily suffers from erosion, contamination, acidification and degradation below that required to support profitable cultivation. For these reasons there is increasing pressure on governments to pass protective legislation and promote best practices for the sustainable exploitation of soil.
