Abstract

Charcoal production is the process of converting wood or other organic material into charcoal through the application of heat in absence of oxygen. To investigate the effect of charcoal production on soil properties, soil samples from ten soil sampling points were collected at a depth of 0-15 cm at kiln site and adjacent fields (control). The study revealed that the earth kiln method used by charcoal producers has significantly increased pH of soil (< 5.5) to be acidic. Soil organic matter (OM) and organic carbon (OC) was high at most areas of the site (74.2%), while others fall within the ranges of low to medium. Available macronutrient status for Nitrogen (0.06 % - 0.23 %) falls within moderate to high ranges while (P, K, Ca, Mg) falls within moderate to high ranges (0.22 Cmol/kg –7.15 Cmol/kg), having few points low in these contents. The availability of micronutrients was highly variable. Zinc (Zn) were moderate at almost all areas, iron (Fe) was low (41.9%), while copper (Cu) was moderate and high respectively across the site (0.18 mg/kg – 0.31 mg/kg). Base on this result it was understood that the coarsening particles resulting from charcoal production has implication for nutrient availability resulting in less nutrients available for crops use. Therefore, the study suggest for an improved method of charcoal production should be used, regulation of indiscriminate felling of trees and woodlot should be established in areas of charcoal production.
