Soil is an important component of the biosphere, and is an absolutely essential component for agricultural production. It is axiomatic that the agricultural self-sufficiency of any country is dependent on availability of good soil and its continuing proper management. Unfortunately this simple fact is often overlooked, resulting in serious socio-economic consequences. Productive soil is being continually lost in both developed and developing countries for a variety of reasons, and the general global trend seems to be continuing increase in the total loss.
