Since historic or prehistoric times crops and plants have grown naturally in the fertile soils. Growth and quality of the crops depend on the fertility of soils. Organic content of the soils contribute to the soil fertility. Population burst and profit orientated approaches to farming, lead to intense farming across the globe. For rapid and higher yields chemical fertilizers are commercially being used since 19th century, deteriorating the soil quality. The quantity of chemical fertilizer added to the fields is increased every year to maintain the same quantity of yield. Because of increase in the addition of chemical fertilizer to the soil, the soil has lost its fertility in many locations across the globe.
