1. Role of Livestock in Natural
Farming :
Perspectives and Strategies
“WASTE TO WEALTH IN RURAL INDIA”

2. Livestock in Natural Farming-Challenges
• Small animal holding per household
• One cattle produces 9-15 kg cow dung and 2-4 litre of
urine-not properly used due to lack of knowledge
• Lack of technology and investment to reuse the waste of
animals in the agricultural field
• Lack of incentivization and encouragement to the
farmers to use animal waste as fertilizer
• Failure of previous bio-gas model.

3. INTEGRATED FARMING SYSTEM
•Farmers have knowledge of keeping animals
along with the crop production- need
scientific management
•Integrated farming can be :
 Crop with Dairy, goat and poultry
 Crop with goat, duck
 Crop with Poultry and fish
 Crop with Sheep management

4. Waste to Wealth: a big opportunity
Rural India generates enormous quantities of bio-waste including animal waste, crop residue, etc.
According to the 20th Livestock Census of India, 2019:
303.31 million
bovines
74.26 million sheep
148.88 million goats
9.06 million pigs
India has
1700 million
metric tonnes
(MMT)
Total dung production (2018-
19)
Biogas = 50% of
India's present LPG
consumption per year
(value Rs. 4400 cr)
Bio slurry = 44% of
India's NPK
requirement (value
Rs. 4250 cr)

5. GOBARDHAN
Pillar to generate wealth and energy by converting cattle dung into biogas and bio-fertilizers
• Aggregate cattle waste and convert it to biogas for domestic and industrial
purposes
• Bio-slurry as a by product of the biogas process, used as bio-fertilizer
• Actively involve the community / SHG / milk coops in management and
operations
• Focus on making the process economically viable for all in the value chain
• Entrepreneurship for large scale production of compressed biogas and
bio-fertilizers

Guiding Principles

6. Gobardhan: Cooperative Led Model
(Zakariyapura, Anand, Gujarat)
• Small-scale or family size biogas
plants in households that have 3 or
more cattle
• Gas generated is purified using a
filter and is used for cooking
• Households get paid for good quality
slurry output is 500-1000 litre, per
month
• Slurry desludged by coop and
transported to a slurry
management unit (for village
cluster)
• The slurry is separated into its solid
and liquid parts ;and converted to 6
types of bio-fertilizers
• Marketed through the milk
cooperative society
HOUSEHOL LEVEL COMMUNITY LEVEL
Household biogas plants in 368 house holds which have three or more cattle

7. Slurry mixed with salt and microbes
Phosphate Rich Organic Manure (PROM)
Solid Liquid Separation
(Mix with more salts)
Solid Liquid
Addition of Rock phosphate
using drum mixer.
Using CSTR, add different
active ingredients to make 6
different products
•Phosphate Rich Organic
Manure (PROM) is considered
as substitute for DAP fertilizer
and costs less than DAP
•Product testing on wheat
crop: significant improvement
in yield by 20%
•Better yield on Napier grass,
banana, chilli, sunflower.

8. Gobardhan: Central Anaerobic digester model
(Banaskantha Milk Union, Gujarat)
• 2000 Cu. M/ day raw biogas produced which is purified as
800 Cu. M/day
• Purified gas is compressed & dispensed as cylinder for
running vehicles
• Dung & spoiled potato collected from farm & households
• Liquid and solid fertilizer produced gets sold to farmers
which is highly ric in nutrients.
• Total investment in one plant is Rs. 800 lakh is recovered
in 6 years.

9. IMPACT OF ABOVE MODELS
• Will help in natural farming by replacing
chemical fertilizer (50-75 % DAP/SSP can be
replaced)
• Help in addressing the stray cattle issue
• Will help in making gaushalas sustainable
• 30 % cost reduction in chemical fertilizer inter-
alia reduce input cost.

10. Natural Farming with Livestock: Way Forward
• An MoU is being signed with Department of Drinking
water & Sanitation (under SBM-2 Gobardhan Project)
and NDDB to translate the above projects into
reality.
• Funding is being tied up under Swachchh Bharat
Mission -2 Gobardhan Scheme.
• Funding from other Departmental Schemes such as
Agri Infrastructure, Paramparagat Krishi Yojna of DAC,
Manure Management Scheme of MNRE and Relevant
component of MNREGA being explored.
