  1. Values are means ± standard deviations (n = 3). Values within the same column followed by different letters indicate significant differences (P < 0.05) according to Tukey’s multiple comparison
  2. Treatment: CK, no fertilizer; M, manure; NPK, chemical nitrogen, phosphorus and potassium fertilizer; MNPK, chemical nitrogen, phosphorus and potassium fertilizer plus manure
  3. Soil properties: AP, available P; AK, available K; TN, total nitrogen; NH4+, ammonium nitrogen; NO3-N, nitrate nitrogen; OM, organic matter
