Ecosystem Management and Conservation of Soil Ecology in an extremely important and complex issue; and this require intergrated approch. The fast urbanization and industrialization due to heavy migration in the Delhi (Study area) have resulted in the loss of fertile soil and thus have changed fertility, productivity and bio-diversity because Soil and land have disturbed the ecosystem. Accelerated soil degradation and erosion is a serious global problem that is widely recognized. Sustainable soil management is not possible without water, land and soil conservation, well planning and development because soil is a complex system where its productivity and fertility depends upon physical, chemical and biological reactions.
