4.1MAKING OF CRH.pptx
1.
2. 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. 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. 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. 3.As water purifier
Activated carbon from CRH filters the dirty
particles in water, making it effective in
purifying household/drinking water.
6. 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. 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. 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. 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

12. Start a fire using the lighter
and firewood and let it kindle
13. Make sure that the fire won’t
die out before covering it
with the Carbonizer
14. Pour and stack the dried rice
hull around the carbonizer.
15. When the rice hull at the top
are carbonized, use the
shovel to cover it with the
dried rice hull from the
bottom
16. 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. Mix the rice hull and let the
remaining embers to
carbonize the rest of the
mixture until all of it (100%)
are carbonized
18. When all of the rice hull are
carbonized, sprinkle water
onto the CRH using the
watering pale to extinguish
the remaining embers
19. Lay the CRH thinly and make
sure that the embers have
died out to prevent the
carbonized rice hull turn to
ash
20. 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
23. Alternative: Make use of defective pressure
tanks. Cut in half to make two carbonizers.
24. Use a metal puncher to make 30-40
holes at 2-cm diameter aligned at 12 x
20 cm distance
