“…The central quality of biochar as a soil conditioner is its highly porous structure, which improves water retention and increases soil surface area (Abd El-Azeim et al, 2021;Nguyen et al, 2022). Study by Liang et al (2006) on sandy soil biochar inclusion demonstrated specific surface area and soil CEC increase relative to untreated soil, since the retention of nutrients in soils often depends on the ability of biochar to adsorb or transport nutrients (Khadem et al, 2021;Haddad et al, 2022)).…”

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 byproducts is better or using them in sandy soil reclamation projects.

“…Than sinh học có khả năng hấp phụ các cation trong đất [37], từ đó làm giảm lượng trao đổi các kim loại trong đất. Than sinh học đã được chứng minh là một chất hấp phụ hiệu quả đối với Al [38], Pb [39], Ni [40] and Zn [41,42]. Cơ chế giải thích cho việc hấp phụ các nguyên tố kim loại của than sinh học có liên quan đến các quá trình như khuếch tán nội hạt, tạo phức với các nhóm bề mặt hữu cơ, trao đổi ion và kết tủa với các nhóm vô cơ [37,42].…”

The presence of metals in soil may impact the environment, as well as agricultural products. Biochar can alter some physical and chemical properties of the soil, reducing the concentrations of exchangeable metals in the soil. The aim of this study was to examine the effects of biochar on the exchangeable metal concentration in two paddy soils that have different organic carbon (OC) contents. A pot experiment was conducted in a greenhouse using two soils with high (3.05%) and low (0.54%) OC content mixed with biochar at rates of 0, 1.5, 3, 6, and 12%, and planted with rice in two consecutive seasons. At the end of each season, 30 soil samples (2 soil types x 5 biochar rates x 3 replicates) were collected to determine the exchangeable concentration of Al, Fe, Mn, Cd, Ni, Pb, and Zn, as well as pH. The metal quality index was calculated using principal component/factor analysis. The results showed that biochar increased the pH value after the first rice crop but did not improve after the second rice season. Biochar reduced the exchangeable concentration of some metals, including Al, Fe, Ni, Cd, Pb, and Zn. Compared to the no-biochar treatment, biochar application increased the soil metal quality index from 4.1 to 12.8% after the first crop and from 9.6 to 188.7% after the second rice crop, depending on soil properties and used biochar rate. This effect could be related to the increased pH in biochar-added soil and biochar's adsorption capacity. In conclusion, biochar has promising prospects for reducing exchangeable metal content in arable soils, thus exhibiting the potential to be used in paddy fields to remediate metal-contaminated soils.
