Till the start of the nineties the use of chemical fertilizer, pesticide and genetically modified seeds became very common among the farmers all over India, and has become the conventional methods of farming. These high input production systems requiring massive quantities of chemical fertilizers, pesticides, irrigation an d machines, however, disregard the ecological integrity of land, forests and water resources, endanger the flora and fauna and cannot be sustained over generations. Green revolution technologies have more than doubled the yield potential of rice, wheat and even other crops and vegetables in our country. But after 55 years, production and productivity reduced drastically with abnormal input costs and the farming sector turned to be unfavorable occupation to all concerned. Soil degradation, more diseases, unc ontrollable weeds, high water consumption, unfavorable price and with several natural and manmade issues, conventional farming turned to be unworthy for farmers. The excessive use of chemical fertilizers and pesticides has led to the accumulation of harmfu l chemicals and toxics in the soil. These harmful products concentrates in the crops and vegetables grown in that soil, which is also termed as ‘Biomagnifications’ and thus causes the chronic health issues such as colon cancer, prostate cancer, hypertensio n, diabetes, blood cancer, kidney failure etc.
