. Biochar utilization is prospective land management to encourage optimization of sub-optimal land. The objective of this paper is to inform of potency of biochar in agricultural aspect especially for rehabilitating of degraded land in Indonesia. In Indonesia, the various sources of raw materials such as agricultural wastes available biochar is quite large reaching 10.7 million t / year, such as rice husks, cacao shell, coconut shell, oil palm shell, and corn cob, etc. Quality of biochar produced depends on the type of raw materials, equipment used, combustion temperature, and duration of combustion. Biochar application on agricultural land serves as soil amendment that can improve soil chemical properties (pH, cation exchange capacity, total-N, available P and Alexch), soil physical properties (bulk density, porosity and water holding capacity). Improvement soil physical and chemical properties impacted on the nutrient availability and water availability through nutrient and water retention. Finally the addition of biochar have been impacted for increasing crop productivity. It is expected that addition of biochar will recover widespread of suboptimal land and then land productivity can be increased.
