Scientists in the soil and related disciplines have often focused their work on agricultural and forest land, overlooking soils of urban, industrial, traffic, mining, and military areas that were left to appear as white areas on maps. It is most likely that the evolution of these soils is a function of the usual formation factors just like any soil category, yet the anthropogenic factor is more intense. In the process, it triggers rapid and irregular transformation cycles comprising addition of exogenous materials and subsequent mixing. These unconventional soils are characterized by extreme spatial heterogeneity. Furthermore, soils in localities may incorporate pollutants inducing environmental degradation and posing potential hazard to human health.  More Details
