Biochar: Pemanfaatan dan Aplikasi Praktis

Biochar is a carbon-rich solid produced from the pyrolysis of biomass such as wood, manure, and leaves under high temperature low oxygen conditions which used for agricultural applications soil amendment. This paper reviews utilization practical application biochar. The biochar into can improve physical, chemical biological properties soil, namely increasing porosity, water holding capacity, aggregation, pH, cation exchange organic carbon, nutrient retention availability, microbial life, meso macrofauna. Aside being amendment, has function on issues global warming, climate change, environment, its role in carbon sequestration stabilization, greenhouse gas emissions, pollutant remediation. If applied properly, using right feedstock materials, method manufacture, dosage, application, place, it will affect agronomic performance crop yields. Reduced yields are mostly occured temperate climates significantly increases pH causing an effect excessive liming resulting immobilization key nutrients Mg, Fe, B, P. needs to be mixed or together with fertilizer ingredients fertilizers, bio-fertilizers, compost, manure. Another effort enrich those materials so that categorized biochar-based higher selling price. Key words : Application, biochar, benefit, method, yield
