Pyrolysis Charcoal Using for Soil Amendment

Abstract

Charcoal is suitable material for soil amendment of tropical areas which is high weathering, enhance low organic matter content and unfertile. Recent investigations gave evidence that incorporation of carbonized material from incomplete combustion of organic substance in the soils leading to higher quality of chemical, physical and biological properties of soil. Such as raise and maintain cation exchange capacity. Elevation of soil pH leading higher base saturation as well as plant nutrient availability, especially phosphorus and calcium. Charcoal from incomplete combustion make a great number of porous and large surface area enhance well aeration as the same time capable to hold some water in the fine pore. Such condition is appropriate for the growth and activity of beneficail microorganisms such as mycorrhiza and nitrogen fixing bacteria. Pyrogenic carbon in charcoal is hardly decay. So that it’s decrease CO2 emission. There for provide using of pyrolysis charcoal as soil amendment have a potentail of decreasing global worming from green house effect.
