  Soil is one of the most critical life-supporting compartments of the Biosphere.It provides numerous ecosystem services such as a habitat for biodiversity,water and nutrients,as well as producing food,feed,fiber and energy.Soils undergo intense and irreversible changes due to a none site adjusted land management and improper application of machinery and techniques in its broadest sense.However,to feed the rapidly growing world population in 2050,agricultural food production must be doubled using the same land resources footprint.
