“Essentially, all life depends upon the soil. There can be no life without soil and no soil without life; they have evolved together.” - Charles E. Kellogg, USDA Yearbook of Agricul‐ ture, 1938. Natural processes and human activities alter the properties and quality of soils over time. The assessment of soil quality entails the evaluation of the capability of a soil to perform its functions not only in present scenarios but also how those functions can be preserved for future land.
