Investigations of carbon dynamics of Eucalyptus and Phragmites feedstock’s made biochar amendments require laboratory soil incubations that provide controlled conditions. The aim was to evaluate the effects of two different biochar amendments on carbon mineralization potential of two different soils. Biochars were produced at 550 °C from the Eucalyptus and Phragmites feedstock materials and at 0, 10, 20, and 40 t ha⁻¹ of doses were mixed with silty loam texture Balcalı and clay texture, Kızıltapır soils. The soil + biochar amendments were incubated under constant temperature (28 °C) and moisture (80% of soil field capacity) conditions for 48 days. In both treatments, the biochar doses significantly increased CO₂ emission After 48 days, both biochars increased cumulative carbon mineralization (Cmin) by more than 20% in Balcalı soil (P < 0.001). The two introduced biochar had a significant impact on Cmin at the end of the incubation period in Kızıltapır soil. Biochars, on the other hand, considerably reduced the rate of Cmin in both soils at a dose of 40 t ha⁻¹. Eucalyptus and Phragmites biochars prepared with concentrations of 10, 20, and 40 t ha⁻¹ have varied effects on soil organic carbon mineralization for both Balcalı and Kızıltapır soils. In general, with increasing biochar doses addition, Cmin significantly increased.

桉树和芦苇原料制成的生物炭改良剂的碳动力学研究需要提供受控条件的实验室土壤孵化。目的是评估两种不同的生物炭改良剂对两种不同土壤碳矿化潜力的影响。生物炭是在 550 °C 下从桉树和芦苇原料生产的，并且在0、10、20 和40 t ha ^-1的剂量下与粉质壤土质地 Balcalı 和粘土质地 Kızıltapır 土壤混合。土壤 + 生物炭改良剂在恒温 (28 °C) 和湿度（土壤田间容量的 80%）条件下培养 48 天。在这两种处理中，生物炭剂量显着增加了 CO ₂排放 48 天后，两种生物炭在 Balcalı 土壤中的累积碳矿化 (Cmin) 增加了 20% 以上 ( P  < 0.001)。两种引入的生物炭在 Kızıltapır 土壤中的潜伏期结束时对 Cmin 产生了显着影响。另一方面，生物炭在 40 t ha ^-1的剂量下显着降低了两种土壤中 Cmin 的速率。以 10、20 和 40 t ha ^{-1 的}浓度制备的桉树和芦苇生物炭对 Balcalı 和 Kızıltapır 土壤的土壤有机碳矿化具有不同的影响。一般来说，随着 biochar 剂量添加的增加，Cmin 显着增加。
