2. CARBONIZED RICE HULL
•Carbonized rice hull (CRH) is made from
incomplete or partial burning of rice hull.
•It is porous and bulky with uniform intact black
particles.
•It contains phosphorous (P), potassium (K),
calcium (Ca), magnesium (Mg), and micronutrients
vital to growing crops.
•Because it is also sterilized, it is free from disease
organisms.
3. USES OF CRH
1. As substrate to
organic fertilizer
•When mixed with other
organic materials like
bokashi, CRH can be a
good source of organic
fertilizer (OF)
4. USES OF CRH
2. As soil conditioner
• Makes the clay soil porous
• Replenish nutrients and other microelements in
the soil that were lost due to continuous cropping.
• Improves soil structure by increasing bulk density,
water holding capacity, and aeration.
• It is a good potting media when mixed with other
materials
5. USES OF CRH
3. As water purifier
•Activated carbon from CRH filters the dirty
particles in water, making it effective in
purifying household/drinking water.
6. USES OF CRH
4. As base material for making microbial
inoculants, Effective Micro Organisms(EM)
• When 30-50% of CRH is mixed with EM
Bokashi , it becomes more useful. Naturally,
CRH is a habitat for beneficial micro
organisms that facilitate composting.
• CRH can be used as inoculant-carrier for
rhizobia, a nitrogen-fixing bacteria found in
the roots of legumes
7. USES OF CRH
5. As Pest Control Agent
•Contains silica that irritates the golden
kuhol.
•When applied after leveling, snails are
forced to come out, making handpicking
faster and easier.
8. USES OF CRH
6. As charcoal for fuel
•Charcoal briquettes from CRH are good
alternative sources of fuel. Compared with
plain rice hull that takes relatively more time
to produce heat, CRH can easily be ignited to
produce heat or convert heat into fuel for
cooking
9. USES OF CRH
7. As deodorizer / odor suppressant
• CRH also cleanses and deodorizes bad air smell through
its activated carbon that absorbs foul odors in the air.
The same principle applies when a charcoal is placed
inside a refrigerator.
• CRH is used as mulch bed in animal pen and poultry
houses to reduce foul smell from urine and manure
11. Dry RICE HULL Carbonizer Shovel
Watering pale
Fire wood (fuel) Lighter or match sticks
12. STEP 1
Start a fire using the
lighter and firewood and
let it kindle
13. STEP 2
Make sure that
the fire won’t die out
before covering it with
the Carbonizer
14. STEP 3
Pour and stack the dried
rice hull around the
carbonizer.
15. STEP 4
When the rice hull at the
top are carbonized, use the shovel
to cover it with the dried rice hull
from the bottom
16. STEP 5
When the rice hull is almost carbonized (80%). Remove the
carbonizer by tipping it over to the side using the long shovel. Extra
caution is exercised for the carbonizer is extremely hot
17. STEP 6
Mix the rice hull and let
the remaining embers to
carbonize the rest of the
mixture until all of it (100%)
are carbonized
18. STEP 7
When all of the rice
hull
sprinkle
are carbonized,
water onto the
the watering
CRH using
pale to extinguish the
remaining embers
19. STEP 8
Lay the CRH
thinly and make sure
that the embers have
died out to prevent
the carbonized rice
hull turn to ash
20. STEP 9
When its dry, collect and store the CRH into sacks. After
that, its ready to be used or sold
22. FOR THE CHAMBER:
Get any 20 L used oil can,
about 40 cm height.
Remove the top cover and
make a hole at the bottom of
the can about9-10 cm
diameter for the chimney
