Description

From the last half of 19th century with the increase in the world's population, food production and fertilizer consumption has increased continuously but, the rate of increase in consumption of chemical fertilizer is terribly high than that of the rate of production increased. Indiscriminate application of chemical fertilizer, mainly nitrogenous fertilizers polluting our habitat in many ways. Our natural eco-system is also being badly affected, soil productivity is in declining phase. The increasing trend of nitrogenous fertilizer application has a long term detrimental effect on environment, human as well as on soil health. The most horrifying aspect of the modern chemical input based intensive agriculture is the rapid fall of chemical fertilizer response . Now we must find an alternative low-chemical resource based energy conserving and natural resource-efficient farming method for achieving long term sustainability in farming system as well as environmental stability confirming food security of the world. Organic farming has expanded rapidly in recent years and is seen as a sustainable alternative to chemical-based agricultural systems .
