Values indicate mean ± SE (n = 3). Different superscript letters in the columns represent significant differences among fertilizer treatments according to one-way ANOVA (Duncan’s test, p < 0.05). EC, electrical conductivity; SOM, soil organic matter; TN:, total nitrogen; TP, total phosphorus; TK, total potassium; CK, chemical fertilizer with conventional fertilization rate; T1, chemical fertilizer reduction by 30% + 6,000 kg ha^–1 bio-organic fertilizer; T2, chemical fertilizer reduction by 30% + 9,000 kg ha^–1 bio-organic fertilizer; T3, chemical fertilizer reduction by 40% + 6,000 kg ha^–1 bio-organic fertilizer; T4, chemical fertilizer reduction by 40% + 9,000 kg ha^–1 bio-organic fertilizer.
