GO GREEN HUSKCHAR
Rice husk charcoal has an important role as a soil-improving material, especially in improving soil physical properties such as porosity, aeration of soil and drainage so as to make it easier for roots to develop and absorb nutrients.
RHC has potential for carbon sequestration, and improv soil fertility and increasing crop production. Biochar is a carbon rich compound produced by the pyrolysis of biomass in a limited oxygen environment. Application of biochar to soil not only improves soil fertility, but also increases water and nutrient retention.
RHC also improve the soil condition and crop production by improving soil chemical characteristics. The addition of RHC to the soil was found to increase the soil pH, available phosphorus (P), soil porosity, Plant Available Water, and also increase the exchangeable potassium (K) and magnesium (Mg).
RHC is characterized by high silicon (Si) content as compared to the other biochar derived from woody materials. Therefore, biochar derived from rice plant can be applied as a source of bio-available Si for Si accumulator crops while increasing organic C storage and soil fertility.
