organic farming prospects and constraints

  1. 1. IS ORGANIC FARMING A NEW CONCEPT Organic farming is not a new concept to our farmers.  Indian farmers were all organic farmers before the advent of synthetic fertilizers, pesticides, mechanization etc BEFORE GREEN REVOLUTION In traditional India only organic farming was practiced.  No chemical fertilizers and pesticides were used.  Only organic techniques where natural pesticides and natural manures were obtained from plant and animal products were used.  During 1950s and 1960s, the ever increasing population of India lead to a food scarcity.  The government was forced to import food grains from foreign countries. And also forced to increase the food grain production of India to increase the food security .
  2. 2. TO INCREASE THE FOOD GRAIN PRODUCTION Was introduced in 1960s under the leader ship of Dr. M.S.Swaminathan
  3. 3. Green revolution technologies (High yielding varieties, chemical fertilizers, synthetic pesticides, mechanization, irrigation) High production (Overcoming food crisis, self sufficiency in food grain, buffer stock of food grain) Not sustainable (Stagnation or fall in productivity, decline in soil fertility, salinity problem, lowering of water table, environmental pollution)
  4. 4. POSITIVE SIDE OF GREEN REVOLUTION  Increased the Country’s food production  Attained self sufficiency  ‘Food deficit’ to ‘food surplus’  Export of food products  Higher income
  5. 5. NEGATIVE SIDE OF GREEN REVOLUTION  Reduction in Natural fertility of soil  Destruction of soil structure  Erosion and soil loss  Killing of beneficial microbes and insects  Ground water pollution and depletion  Atmospheric pollution  Soil acidification  Chemical burn  Mineral depletion
  6. 6. Health effects of conventional farming: • Asthma • Birth defects • Neurological effects • Cancer • Hormone disruption • Parkinson’s disease
  7. 7. Relationships between chemical input levels and sustainability
  8. 8. • With introduction of green revolution, use of chemical fertilizers although contributed 40% of crop production, continuous use of chemicals in agriculture seriously destroyed the soil health and environment. • The scientists have realized that the ‘Green Revolution’ with high input use has reached a plateau and is now sustained with diminishing return.
  9. 9. What does organic farming means?  The aim of organic farming is to maintain optimum soil health and thus making the soil capable of supplying all essential nutrients to crop for its proper growth and development Organic farming aims at sustaining and increasing the productivity by improving soil health and over all improvement of agro-ecosystem Organic farming gives quality organic food and also helps to restore soil fertility on long term basis. As per the definition of the United States Department of Agriculture (USDA) term organic farming refers to “organic farming is a system which avoids or largely excludes the use of synthetic inputs (such as fertilizers, pesticides, hormones, feed additives etc) and to the maximum extent feasible rely upon crop rotations, crop residues, animal manures, off-farm organic waste, mineral grade rock additives and biological system of nutrient mobilization and plant protection
  10. 10. IMPORTANCE OF ORGANIC FARMING: Present burning issue in farming is the decline in fertility of soil and fall in productivity levels. Use of chemical fertilizers and synthetic pesticides have deteriorated soil health as well causing harm to our natural eco-system by polluting our environment as well as water. Now we have reached a situation were productivity levels in soil slowly decreasing day by day. Now its time to go for organic farming and restore soil fertility and maintain soil fertility on sustainable basis so that future generations may not face problems
  11. 11. DIFFERENCE BETWEEN CONVENTIONAL AND ORGANIC FARMING CONVENTIONAL ORGANIC It is based on economical orientation It is based on ecological orientation GMOs are used GMOs are not used here Synthetic fertilizers are used Synthetic fertilizers are not used Weeds are controlled through herbicides Manually weeds are removed here Pesticides and fungicides are used to control pest and diseases Pest and diseases are controlled biologically Produce obtained will have chemical residues accumulated in it Produce is free from chemical residues Air, water and soil pollution is common No such problem is observed Produce is carcinogenic and causes several health problems No such problems are observed here Low input: output ratio with pollution Optimum input: output ratio with no pollution Soil fertility is maintained for shorter period Soil fertility is maintained on long term basis Intensive irrigation is required Irrigation requirements are reduced
  12. 12. Objectives of Organic Farming Produce food with higher nutritional quality Work with natural system Maintain and increase soil fertility Use renewable resources as far as possible Wider social and ecological impact of farming system Allow satisfaction to agricultural producer Avoid Pollution Objective of organic farming (1) (2) (3) (4) (5)(6) (7)
  13. 13. Components of organic farming
  14. 14. Principles of organic agriculture
  15. 15. MAIN PRINCIPLES OF ORGANIC FARMING: The main principles of organic farming are as follows:  To maintain the long-term fertility of soils.  To avoid all forms of pollution that may result from agricultural techniques.  To produce foodstuffs of high nutritional quality and sufficient quantity.  To reduce the use of fossil energy in agricultural practice to a minimum.  To give livestock conditions of life that confirm to their physiological need.  To make it possible for agricultural producers to earn a living through their work and develop their potentialities as human being.

  47. 47. LIST OF COMMODITIES WITH POTENTIAL FOR ORGANIC PRODUCTION IN RAINFED REGIONS Venkateswarulu (CRIDA)
  48. 48. Advantages of organic farming: Organic matter supplies all the essential macro and micro plant nutrients. Organic matter improves physico-chemical and biological properties of soil. Organic farming improves agro-ecosystem and helps in stopping environmental degradation . Organically grown crops are preferred by most people as it is believed to be more nutritious compared to conventional ones. Organic produce fetches more prices in national and international market.
  49. 49. CONSTRAINTS OF ORGANIC FARMING:  Organic manure contain fewer amount of nutrient.  Lack of awareness  Marketing problems of organic inputs and out puts  Shortage of organic biomass  Poorly supporting infrastructure  High input cost  Lack of suitable agriculture policy  Lack of financial support  Low yields during conversion period  Political and social factors  Complex certification procedure  Lack of organic input responsive variety Meena et al (2013)
  50. 50. Limitations of organic farming in India  Small land holding  Poor infrastructure facilities  Lack of technology knowledge  Convert organic farm  Organic material such as animal dung and other crop waste used for fuel purpose  Organic material are bulky in nature very difficult store and high price  City garbage contain heavy metal, plastic bags, stones and needles.  Bio control agent are available only few selected insect pest.  Complicated organic certification process and high fees cost  Higher human population of India.
  51. 51. Debated issues on organic agriculture: Can organic farming produce enough food for everybody? Is it possible to meet the nutrient requirement of crops entirely from organic sources? Are there any significant environmental benefits from organic farming? Is the food produced by organic farming superior in quality? Is organic farming economically feasible? Is it possible to manage pest and disease in organic farming? Munda et al.
  52. 52. SUGGESTIONS TO PROMOTE ORGANIC FARMING: Many changes are needed if India is to overcome the constraints and achieve its rich potential in organic agriculture. Developing appropriate and strong extension services. Developing strong linkage between producer and consumer. Reducing the cost of certification and easily approachable to farmer. Making the organic inputs available to small holders like bio-fertilizer and bio-pesticide. Developing the domestic market. Providing subsidies and other financial support. Improving infrastructural facilities like cold storage and transportation. Enhancing linkages in the supply chain promoting research on organic agricultural research and development. Providing regular training on organic agriculture. Meena et al.(2013)
