Biochar has gained significant attention for its potential in carbon sequestration, soil health improvement, and crop production sustainability. However, the existing studies predominantly focus on short-term experiments conducted acidic or neutral soils. This study investigates long-term effects of biochar application a calcaric cambisol field experiment with four treatments: CK (no fertilizer biochar), B (only NPK (chemical fertilizer), NPKB (combination chemical biochar). assessed organic (SOC), sorghum yield, bacteria, plant nutrient accumulation 2020 2022, properties after 12 years consecutive 2022. The results revealed increase SOC due to both 2022 compared treatments without biochar. 12-year also significantly enhanced total nitrogen (N), available phosphorus (P), potassium (K), irrespective application. Notably, N P remained unaffected by biochar, induced was even lower than that treatment Furthermore, bacterial diversity composition, as well showed no alterations years, despite increased content. These findings affirmed benefits through cambisols, but positive were found be negligible.
