2. CONSTRAINTS IN ORGANIC FARMING
 Production of poor quality inoculants /manures without
understanding the basic microbiological techniques
 Short shelf life of bio fertilizers.
 Lack of essential equipments, power supply, etc.
 Space availability for
laboratory, production, storage, etc.
 Lack of suitable training on the production techniques
 Unawareness on the benefits of the technology.
 Non availability of right inoculants at the right place in
right time.

3. OBJECTIVES
 To provide an user friendly and cheap microbial technique to farmer for
self production of bio fertilizer.
 Recycling and enriching of agricultural wastes into quality organic
manures and related by products within a short period of time.
 Producing an opportunities for sustainable and profitable agricultural
practises to target population.
 Providing an user friendly Compost Models.
 Providing an user friendly tools for Organic Farming.

5. COMPOST TUMBLER TECHNOLOGY
 A tumbler consists of an UV insulated rotomoulded
plastic vessel, which has three layered insulation foam.
 Due to insulation material compost pile gets hot very
quickly and accelerates decomposition of waste.
 Drum can be rotated with the help of handle; turning
of compost pile will become very easy

11. Preparation of Phosho-Compost
 Shredder machine= Can cut branches up to 10-12 mm
diameter. Also useful to shred dry leaves, green grass,
and other agricultural waste. An ideal tool for
composting and mulching.
 Power= 2 hp single phase motor/ can be attached to
Diesel Engine. Capacity is 200 kg waste /hour

14. Preparation of Mixed Organic Fertilizers
 Conventional farm yard compost contains 1.4%
Nitrogen, 1.8% Phosphorous and 0.7% Potassium. By
adding certain organic elements this compost can be
enriched in nutrient composition.
 Compost tumbler enable the farmers to mix the
content uniformly, with minimum manpower,
and requires very short period of time.

15. Preparation of Rapid Vermi compost
 As earthworms can’t tolerate heat generated during
primary decomposition of waste, heaping process is
necessary before inoculating in earth worm bed. In
normal conditions heaping required 30-45 days. But by
using tumbler technology within 8-10 days this process
can be achieved.
 Hence cycle time of preparation of vermi compost
reduced to 45 days from 90 days

16.  Prime objective of this project is to prepare a role
model for production of in house bio fertilizers,
and P- enriched compost from agricultural
wastes. By which people living there got a
sustainable and profitable revenue generation
scheme.

19. Benefits to Target Population
 By using self prepared compost, vermin compost, bio fertilizer; farmers
can achieve a great yield without hampering soil profile. Hence for
sustainable agriculture this model is very important.
 Farmers can produced quality organic fertilizers from the farm waste
which can be sellable in market giving a continuous revenue generation
scheme.
 There will be no requirement of outside fertilizers; technology is
complementary with organic farming.
 Farm waste will be taken for process instead of burning. So creating good
environmental conditions within village. Also open dumping of waste will
be restricted, prohibiting bad odour, and other nuisances.
 Together all, waste management within village level can be ideal for clean
and green environment.

20. Scope of Project
As the problem of getting quality organic manure becoming a serious
issue, proposed tumbler technology provides an ideal solution. Farmers
can develop their own bio fertilizer, compost and vermin compost within
a short period of time and using very cheap microbial techniques.
Proposed model can be replicated at every village, farm, food
processing units, major cities, hotels, and every place where waste is
generated!
Due to its unique features, this model can be replicated very rapidly in
various sectors of society.
