According to a report by the DOST, 2.5 million tons of rice hull or "ipa" are just thrown or burned from the milling of 13 million tons of palay. The regulated burning of raw rice hull produces carbonized rice hull (CRH).
CRH contains calcium, potassium, phosphorus, calcium, magnesium, and other elements necessary for soil conditioning. It also enhances water retention. Also, because CRH is sterile, it is free from disease organisms.
We saw the design of the carbonizer after attending the organic farming seminar conducted by the Department of Agriculture. Because we want to use bioorganic fertilizers in the farm, we made our own carbonizer so we can convert the rice hull into CRH. Here is our own version.
|After making some fire, we cover the fire with our DIY carbonizer. Then we put rice hull around the carbonizer until the mound reaches the chimney.|
|After 30 minutes, we mix the mound and move the rice hull from below to the top of the burning mound.|
