In The Philippines I stumbled upon a technique, introduced by a company
that started leasing 400 hectares from local farmers to grow rice on it.
They say that because the soil has become very acidic due to the abundant
use of chemical fertilisers in the past, it needs de-acidification first.
How do they do it, agricultural lime? No, that costs about US$200 / ha in
purchasing it alone.
What they say is that culturing lactobacillus in water and mixing it with
carbonised rice hull, that will do the trick at a fraction of the costs.
Is there anybody in this group that could confirm that it really works
that way?
thanks.
