Soil is not a static object that can be described once and for all, but a natural entity with a time dimension. Soil genesis study describes the influence of soil forming factors such as climate, parent material, relief, topography and effect of one or more soil forming processes on soil evolution with time under different conditions. Highest rates of soil genesis are found to be associated with more humid climatic conditions and periodic water saturation. Prolonged water saturation under humid climatic conditions lead to the development of soil with change in chemical and morphological properties. Redox processes promote gleying and accumulation of acid organic compounds in these soils. Ferrolysis is described as a dominant process to explain clay disintegration, interlayering of clay minerals in water saturated soils either due to seasonal alteration and prolonged water saturation and is considered as a characteristics profile forming process. Clay disintegration and interlayering of clay minerals along with change in pH and cation exchange capacity of the soil do not promote soil health in a sustainable basis. Remediation of soil undergoing ferrolysisis required for the maintenance of good soil health.
