Effect of tea waste biochar (TBC) and Zeolite (ZL) on catalase (CAT), superoxide dismutase (SOD), glyphosate residue in soil, and glyphosate residue in leaf in maize. Mean values (± SD) are based on three independent replicates. Variations among treatments were statistically verified using Fisher’s LSD at a 5% probability level, where non-matching letters denote significant differences.
