usage
Use of fertilizer is very low standing at 2-8%
for inorganic fertilizer and 24.9% for organic
fertilizer. IF 1 kg/ha and is below the Sub-
Saharan Africa average of 9.6 kg/ha.

Ag/household waste
Organic fertilizer is largely
‘home grown’
ISFM techniques such as
mulching, fallowing;
submersion of crop residues,
bunds (soil, grass and stone) to
control soil erosion.
Some use of animal manure
and compost
With these practices plus
supplementary CS
technologies such as UDP
good increases in yield

initiatives
• Landfill in Kampala (3 sites)
• Uganda solid waste
composting program,
funded by World Bank and
managed by National
Environmental Management
Authority (NEMA).
• Biogas
• Biochar – R&D

SWM - Lira composting facility
Aerobic windrow composting;
leachate is applied to windrow
as a source of composting
inoculum
35 tonnes p/d SW generated
from 2/4 divisions.
95% of waste received is
biodegradable
C/N ratio is too low at 12.
Two revenue sources; carbon
credits. 2,500 USD received
from 2011; sales 9MT per week,
but, demand is low
9. IFDC
Case study..challenges
Collection and sweeping
isn’t done efficiently
(managed by divisions)
Waste segregation is
done on site manually.
Some hazardous
Operational funds
required to cover repairs
15 USD p/t plus transport
High application rates. 2-3
tons p/a for heavy feeder
crops maize, potatoes.
A large percentage of
solid waste still dumped
10. IFDCCase study 2 – Biochar research,
5km from central Kampala
Raw Materials used to make Biochar organic
fertilizer.
• Charcoal powder- helps in retaining water and
nutrients in the soil, stabilizes soil PH. Terra preta.
• Inoculated animal / municipal waste from a bio-
digester.- free from CH4 gases, and rich in Nitrogen.
• Vermiculite and Betonite. –Rich in K, Mg, Ca, P,
and other micro nutrients.
• Ash- Rich in K.
• Phosphates mixed with bamboo vinegar to convert
P to P2O5.

Biochar cont
Min factory set up of capacity 3 tones daily, Three outlets,
in Uganda.
Demonstrations and field trials on different crops in
collaboration with other government research institutions
like UIRI, MUK, NFA, Agriculture etc.
We have also done several laboratory tests
We are in process of securing product certification from
Ministry of Agriculture of Uganda and IMO.
NFA sole supplier of forest inputs.
15. IFDC
General challenges
In general awareness about benefits of composting
limited
Lack of collection and sorting systems
Lack of incentives for private sector
Transportation costs
Poor market research/lack of marketing
More emphasis on safe disposal than compost quality
Negative balances may not be offset by MSW (1-3%)
however potential from human excreta greater (17-60%)
16. IFDC
Opportunities
Some skepticism about use of inorganic fertilizers
Problems with inorganic fertilizer supply chain
In Kampala 28,000 tons of waste is collected and
delivered to landfill sites every month most of which is
simply burnt
Other urban areas high biodegradable content of SW
Middle class consumer interested in quality
More focus on higher value crops in peri urban use of
processed liquid fertilizer (by mixing and fermenting
molasses, animal droppings and plant tissues), for
orchards, banana plantations, horticulture crops, home
flower gardens.
