“…The highest available soil N in tomato and cabbage fields was recorded with INS, while maximum K and SOC were obtained with VC (Choudhary et al ., 2003). Organic compost contains bacteria, actinomycetes and fungi; hence, a fresh supply of humic material not only added microorganisms but also stimulate them (Balasubramanian et al ., 1972; Gaur et al ., 1973). Microbes in rhizosphere provide benefits to crops by better nutrient availability through mineralization of organic N, atmospheric N-fixation or solubilizing fixed mineral forms of P and other nutrients (Hegde et al ., 2007).…”

The hill ecosystem of Northeastern Himalayas is suitable for organic farming due to negligible use of fertilizer (<12 kg ha −1 ) and agrochemicals, abundance of organic manure, especially plant biomass, and favourable climatic conditions for diverse crops. For successful organic farming, efficient cropping systems and organic amendments are to be identified to sustain soil health on one hand and productivity and enhanced income on the other. The efficacy of three organic amendments, namely, farmyard manure (FYM), vermicompost (VC) and integrated nutrient source (INS; 50% recommended dose of nitrogen (N) through FYM + 50% N through VC) on performance of three-vegetable-based cropping systems, namely, maize + soybean (2:2 intercropping)-tomato, maize + soybean-potato and maize + soybeanFrench bean was evaluated for five consecutive years (2005-06 to 2009-10) under subtropical climate at Umiam, Meghalaya, India (950 m above sea level). All the organic amendments were applied on N equivalent basis and phosphorus (P) requirement was compensated through rock phosphate. The results revealed that the yield of vegetables, except root vegetables, was maximum with FYM as soil amendment. Total system productivity in terms of maize equivalent yield (MEY) was significantly higher under FYM followed by INS. Pooled analysis revealed that MEY was enhanced by 200 and 191% with continuous application of FYM and INS, respectively, over control (no manure). Maize + soybean-tomato system recorded the highest MEY (28.78 Mg ha −1 ; Mg -megagram) followed by maize + soybean-French bean (24.37 Mg ha −1 ). INS as organic amendment resulted in maximum improvement in soil organic carbon (SOC), available P and potassium (K), soil microbial biomass carbon and water holding capacity and was similar to those under FYM. The SOC concentration under INS (23.6 g kg −1 ), FYM (23.3 g kg −1 ) and VC (22.3 g kg −1 ) after five years of organic farming were 31.0, 29.4 and 23.8% higher than the initial and 26.2, 24.6 and 19.3% higher than those under control, respectively. The quality traits of tomato such as total soluble solids (5%), ascorbic acid (28.6 mg 100 g −1 ) and lycopene content (19.35 mg 100 g −1 ) were higher under FYM application than other amendments. The study indicated that FYM and INS are equally good as organic amendment and their continuous application not only improves soil health but also crop productivity. FYM application was also found to be cost effective as it resulted in a higher benefit: cost ratio (4.4:1) compared to other amendments irrespective of cropping sequences during transition to organic farming.

“…21 Compost contains bacterial, actinomycetes, and fungi; hence a fresh supply of humic material not only added microorganisms but also stimulated them. 22,23 Composting material added plenty of carbon and thus increased heterotrophic bacteria and fungi in soil and farther increased the activity of soil enzymes responsible for the conversion of available form of nutrient. 24 The higher soil microbial activity due to organic farming may be higher soil respiration due to the stimulation of heterotrophic microorganisms.…”

To understand the soil health under continuous cultivation after using organic and chemical inputs, a survey was conducted under Uttarakhand, Navdanya farm areas, where farmers was selected who were practicing both chemical and organic inputs under different crops at least more than 5 years. The effect of most important crops growing under Uttarakhand i.e wheat, potato, garlic, mustard, chick pea, chilli and pumpkin was taken into consideration. The results clearly suggested that a significant decline in most important soil enzyme activities like dehydrogenase, esterase, acid and alkaline phosphatase under chemical farming as compared to organic farming. The microbial population especially fungi, bacteria, actinomycetes, azotobacter and nitrosomonas was significantly higher under organic farming areas than chemical farming. The results clearly showed that organic farming has a great role to maintain excellent microbial and enzyme activities resulted better soil health status.

In the post independence period, the most important challenge in India has been to produce enough food for the growing population. Hence, high-yielding varieties are being used with infusion of irrigation water, fertilizers, or pesticides. This combination of high-yielding production technology has helped the country develop a food surplus as well as contributing to concerns of soil health, environmental pollution, pesticide toxicity, and sustainability of agricultural production. Scientists and policy planners are, therefore, reassessing agricultural practices which relied more on biological inputs rather than heavy usage of chemical fertilizers and pesticides. Organic farming can provide quality food without adversely affecting the soil’s health and the environment; however, a concern is whether large-scale organic farming will produce enough food for India’s large population. Certified organic products including all varieties of food products including basmati rice, pulses, honey, tea, spices, coffee, oilseeds, fruits, cereals, herbal medicines, and their value-added products are produced in India. Non edible organic products include cotton, garments, cosmetics, functional food products, body care products, and similar products. The production of these organic crops and products is reviewed with regard to sustainable agriculture in northern India.
