In recent years, it has become a very common application for the purpose of obtaining biocarbon (BC) from various organic waste and improving the properties of agricultural soils. Although there are many studies on the use of biocarbon in the healing of alkaline soils, studies on its effects on acidic soils are limited. Therefore, an incubation trial was conducted to investigate the properties of a acidic soil and its effects on carbon (C) mineralization. The soil samples were added by weight 0 (control), biokemur of wing-down (PLBC) at 2% and 5% according to the weight basis, and were left in incubation for 120 days at 27 °C for a period of 30 days. The pH of the soil with the application of PLBC ends the incubation time from 4.38 to 5. It rose to 31. The value of electrical conductivity (EC) has also increased. The CO2 emissions (CO2) reached the maximum in the 30th day of incubation for each of the control and PLBC applied soil samples. PLBC has significantly increased the organic content of the soil. The values were controlled at a level of 3.51, 4.70 and 6.27 per cent for 2 and 5 per cent respectively. The application of PLBC has shown an increasing negative effect on soil's C mineralization. Particular organic substance (POM) values have shown that PLBC applications increase organic carbon storage. PLBC applications have shown a carbon storage in the soil as well as a soil-regulating effect. The results obtained by a short-term incubation work under controlled conditions will be more beneficial to support by greenhouse and land work.

During the last years, biochar (BC) from various organic wastes and its application to soil to improve soil properties have been a very common treatment in agricultural soils. While many studies have been conducted on the effects of biochar on the improvement of alkaline soils, studies on acid soils are limited. An incubation experiment was conducted to investigate the effects of poultry litter biochar (PLBC) on acidic soil properties and C mineralization. Biochar derived from poultry litter (PLBC) through slow pyrolysis was mixed with soil in three different doses (0, 2, and 5%) and subjected to a 120-day incubation period. pH increased from 4.38 to 5.31 at the end of the incubation. Electrical conductivity (EC) values also increased. Carbon dioxide (CO2) emission reached its maximum on the 30th day of the incubation in control and with PLBC applied to the soil. PLBC increased the organic matter (OM) content of the soil. Values were 3.51%, 4.70%, 6.27% for control, PLBC 2% and 5% treatments, respectively. PLBC does have an increasing negative priming effect on the carbon (C) mineralization of the soil. Particulate organic matter (POM) increased the storage of organic carbon (OC) in the POM fraction for both PLBC applications. It is revealed that PLBC showed soil conditioning effect as well as C storage in the soil. This study was on the short-term incubation under controlled conditions, varying results would be obtained in field conditions.
