Carbonized Rice Hull (RCH) prepared with a Rice Hull Carbonizer (RHC)

Jun Guarin was resourceful enough to have our improvised Rice Hull Carbonizer (RHC) prepared by one of his friends. Mang Brillante Pascual has been using the RHC since to prepare Carbonized Rice Hull (CRH) from the free rice hull requisitioned by our core volunteer team from one of the rice mills in Naguilian (?).

The process of preparing Carbonized Rice Hull (CRH) using the Rice Hull Carbonizer (RHC) was based from a video prepared by PhilRice. Carbonized Rice Hull (CRH) would be a good source of phosphorus (P) and potassium (K) plus some other trace nutrients coming from an organic waste of farming. Relying on and recycling back the waste products of the farm systems is a key component of the EcoCulture system that we are espousing.

The Carbonized Rice Hull (CRH) prepared using the  Rice Hull Carbonizer (RHC) has higher "carbon" (more black in color) than the  Carbonized Rice Hull  and Rice Hull Ash (CRH-RHA) mix coming from the rice mill dryer system. The CRH-RHA mix (grayish black in color) may have higher percentage of whatever nutrients present in mix compared with the  Carbonized Rice Hull (CRH).

Activated carbon is known for its high adsorbing capacity, thus the abiiity to "sequester" organics and ions. This property is exploited in the "Biochar" approach in an attempt to sequester nutrients in the soil that may otherwise be leached out and carried away due to water runoff during the monsoon season.  The efficacy of "Biochar" however is controversial and will need further study.

Photos in this series were taken by Jun Guarin and Dhom Pascual.
