Setting up of Community Vermicompost Unit
  • Problem /need addressed by technology developed:
    As far as organic farming, application of quality inputs at appropriate time would contribute to increase in yield of crops. Vermicompost is one such input adopted by organic farmers. Commercially, this is not available in all fertilizer shop. This made us think to develop a model - Community Vermicompost Unit where farmers can get good quality vermicompost and it serve as income generation source for the community. Secondly, making of vermicompost can be done by using locally available raw materials. These raw materials include cattle dung or leaf compost. This organic manure is available within the vicinity of the rural women.
  • Description / specification of technology developed:
    This is the community owned enterprise where farmers can buy the inputs at lesser cost, this unit serves as input facilitation centre for quality organic inputs in Nagapattinam District. e.g, Biofertilisers, biopesticide are also available for sale.

    Vermicompost is the result of treatment of such low quality organic manure (high C: N ratio) and converting them into high quality organic manure (low C: N ratio). The quality of organic manure is inversely proportional to the C: N ratio of the manure. This process of conversion is made possible by earthworms which digest organic manure and the entire process of conversion is completed for one batch within 30 days.

    The final produce in the form of vermicompost is a moist granular produce which can release nutrients immediately to crops, unlike raw organic matter, which needs to be decomposed in the first place.

    Chemical and biological parameters of vermicompost are given below:
    S.No. Parameters Vermicast Normal Range
    1. pH 6.5 - 7.5
    2. Organic Carbon (%) 15 – 20
    3. Nitrogen (%) 1.3 - 1.7
    4. Phosphorus (%) 1.2 - 1.8
    5. Potassium (ppm) 800 – 1850
    6. Carbon : Nitrogen 14 - 15 : 1
    7. Calcium % 3.0 - 4.5
    8. Magnesium % 0.4 - 0.7
    9. Sodium (ppm) 400 – 500
    10. Sulphur (%) 0.003 - 0.04
    11. Iron (%) 0.3 - 0.7
    12. Zinc (%) 0.028 - 0.036
    13. Manganese (%) Traces to 0.04
    14. Copper (%) 0.0027 - 0.0123
    15. Boron (%) 0.0034 - 0.0075
    16. Aluminum (%) Traces to 0.071
    17. Cobalt, Molybdenum In available form
    18. Nitrogen Fixing Bacteria (cells/gm) 2.5 x 106
    19. Phosphate Solubilizing Microbes In sufficient quantities
    20. Beneficial Fungi (spores incl.) In sufficient quantities
  • Purchase cost of technology:
    Vermicompost production cost per kg: Rs. 4.00
    Sale cost per kg: Rs. 6.00 
  • Number and location of trainings given to operate / use technology developed:
    Seventy nine programmes has been conducted as part of this programme. Totally 520 members from 35 groups were trained (both women and men) on production of Vermicompost production.
  • Number / units of technology developed disseminated in the field as part of core support programme:
    Ten community vermicompost production units are established in three districts viz. Nagapattinam Tiruvannamalai and Kanchipuram.
  • Number / units direct beneficiaries of the technology developed:
    • Totally 136 farm women involved in vermicompost production.
    • Due to this unit, totally 2,250 acres were benefitted and 1058 farmers spread over 52 villages were benefitted by this activity in Nagapattinam District.

  • Number and name of enterprises created which are benefitting from / utilizing technology developed:
    Name of the District Name of the Unit/Village Size of the Shed No of Women Total Production – Apr. to Nov. 2014 (kg)
    Kancheepuram Shakthi Vermicompost 40’x 20’ 10 1,500

  • Amount of increase in income enhanced by utilization of technology developed:
    • On an average, Rs.300 to Rs.500 has been saved in adopting this technology in paddy crop in a year in one acre (2 seasons).
    • Due to the units, each women involved in vermicompost production are able to obtain Rs. 700 to Rs. 900 income per month
