| Abstract | ||
| Biochar ash is a waste product of traditional charcoal production process in the absence of oxygen and consists of cement-like organic matter dust collected from traditional kilns floor. This study tested the changes in some soil physical properties and the establishment of ryegrass cover area as a natural landscape resulting from the application of biochar ash mixed with organic waste in clay and sandy soil. Biochar ash (BA) collected from kiln dust waste was applied as an equal mixture with farmyard manure (BA/FM) and poultry manure (BA/PM) at dry weight basis to 10 kg soil pots in the greenhouse at different rates of 0, 2, 4, 6, 10%. Mixtures of BA/FM or BA/PM addition increased clay and sandy soils water holding and available water capacities at all application rates compared to control. Soil aggregate stability against water increased significantly as the mixture rate addition increased. Relative to the control, mixture of biochar ash and manure amendment decreased the dispersibility of soil aggregates and had significant effects on soil aggregate stability. Soil physical improvements were not significantly different when BA mixed with FM or PM. Incorporation of biochar ash mixture into sandy or clay soil has established sufficient landscape of ryegrass covering area to prevent erosion compared to control. Once the agronomic benefits and environmental impacts of using biochar ash as a soil amendment have been identified, an environmental and economic feasibility study should be conducted to determine whether landfilling biochar by-products is better or using them in sandy soil reclamation projects. | ||
