To evaluate the long-term effects of biochar application on soil acidity, organic carbon, and nutrient dynamics in a wheat-pea rotation system.
Applied biochar derived from forest waste at varying rates (11.2, 22.4, 44.8 t ha-1) only once in 2013.
Compared biochar-amended plots with non-amended control and nitrogen-only fertilized plots.
Measured key soil properties including pH, SOC, cation exchange capacity, and mineralization rates over 10 years.
Biochar application significantly increased soil pH by up to 0.9 units.
SOC stocks rose by 95-207% immediately and remained elevated for over a decade.
Higher biochar rates improved cation exchange capacity, enhancing nutrient availability.
