Abstract

Biochar shows interesting and environmentally useful properties, among which is its relatively high cation exchange capacity (CEC). High CEC may lower the easily plant available heavy metals in soils due to the increase in the soil adsorption capacity resulted from biochar application. Quite a lot of current researches reveal that the extracted heavy metals in tropical soils particularly Cu and Zn were significantly lowered in the presence of biochar at 5-10 Mg ha-1. Heavy metal contaminated tropical soils planted with corn plant (Zea mays L.) show significant decreases in Cu and Zn concentrations at moderate and high-level addition of heavy metal containing waste. The growth and dry-masses of roots and shoot of corn plant improved immediately as a result of biochar amendment. Planting heavy metal polluted soils treated with biochar with thorny amaranthus (Amaranthus spinosus) also demonstrated similar phenomenon.
