ABSTRACT
In addition, numerous “soil quality” evaluation systems have been used for the purpose of revenue assessment in several ancient cultures around the world. Soil quality, according to these systems, was rated in relative terms, with the highest value of one for the best quality soil. A possible approach would be to apply the concepts of soil quality to understand the processes of soil erosion, especially with regard to erosion-induced changes in productivity. One of the major limitations of the soil quality concept lies in its subjectivity, vagueness, and qualitative approach. Similar to soil quality, the problems of accelerated soil erosion have plagued the earth since the dawn of settled agriculture. The literature on soil erosion and methods of its mitigation is voluminous and diverse, and many ancient civilizations have struggled for millennia with the tough challenge of keeping the soil in place.
