Soil pH, EC, and CEC analysis in the biochar and inorganic fertilizer treatment.

Treatment	pH1	EC1	CEC1
Wfbb	4.92 ± 0.8	0.2 ± 0.03	16.28 ± 1.9
Bcb	5.38 ± 0.9	0.23 ± 0.01	18.23 ± 2.1
Bga	6.43 ± 1.2	0.42 ± 0.02	28.08 ± 3.8
If a	6.74 ± 1.0	0.33 ± 0.03	25.36 ± 3.5

Bg = biochar grass; Bc = biochar chat; If = inorganic fertilizer; Wfb = control plot (free from biochar and fertilizer). ¹Mean of the four-treatment pH, electric conductivity (EC), and cation exchange capacity (CEC). Treatments with the same letters were not significantly different at p ≤ 0.05.
