REUSING WOODS AND LEAVES – THE RAMIAL CHIP WOOD
Applying RCW on a seedbed
One of the key methods of
going green is to reuse things around us. This week I write about an innovative
method of reusing wood. This I learnt during my training at the Songhai Centre
Port- Novo, Benin Republic. You can read about my Songhai Experience here. This
very interesting method is referred to as Ramial Chip Wood Application (RCW).
CHIP WOOD (RCW)
Ramial chip woods are
gotten from the crushing of stems, branches and leaves that are non- acidic for
fertilization of the soil. The application of chipped wood is done to replicate
the effect of natural falling leaves from a tree to the soil and the effect it
has after decomposition. Non-acidic wood is said to be used here majorly and
decomposition start at about 7 to 8 months. It should be noted that one could
have 80% - 20% ratio of non- acidic to acidic wood.
Ramial chipped wood is
considered the number one means of fertilizing the soil. There is also a
secretion of various antibiotics from bacteria in the chip wood. This helps to
protect crop from certain attacks.
Ramial chipped wood is not
immediately functional. Thus it is good to mix the use of both RCW and compose.
It actually takes 2-3 yrs to start fertilizing the soil. The interesting thing
however is that research work shows that such soil fertilized by RCW remains
same for another five (5) years.
·Maintains soil humidity
·Contributes to destroying weeds
·Fertilization of the soil
·Long time preservation of soil nutrients
·Protection of crop from certain attacks.
·A good material for mulching
It is however important to note that RCW result in
carrying out deforestation especially when entire trees are cut down. Thus it
is emphasis to replant after cutting down old tress.
