Abstract: 

The fertility of agricultural land is a function of the amount of organic material available in the soil. Due to the low amount of this material in the agriculture soil, use of organic materials is important. Biochar is a kind of organic materials which has high stable properties, in recent years attracts the attention of researchers. The goal of this research was to study the effect of sugarcane bagasse biochar on some chemical properties of a sandy loam soil. For this purpose, from prepared biochar in different temperatures of 200-600°C, biochar products in temperature of 300 °C which had the highest stable organic matter yield index (7.2%) was selected as the optimum biochar. Then the effect of this organic matter, after mixing it with a sandy loam soil at 4 levels (0, 2, 5 and 10 g per kg soil), on chemical characteristics of this soil, such as organic carbon, total nitrogen, available phosphorus, cation and anion exchange capacity were determined. The results showed that the addition of sugarcane bagasse biochar in all levels caused increasing significant of organic carbon, total nitrogen, available phosphorus, anion exchange capacity, EC, cation Exchange capacity and decreased pH of the soil. Sugarcane bagasse biochar with treatment of 10 g per kg soil showed greatest impact on anion exchange capacity of the soil (7.4 times compared to the control) and the lowest impact on the reduction of soil pH (0.01 times compared to the control).
