Data are means ± standard errors. Different letters and bold words indicate statistically significant differences among sections (p < 0.05). OM, organic matter (mg/kg); TN, total nitrogen (mg/kg); TP, total phosphorus (mg/kg); OP, organic phosphorus (mg/kg); NO3−-N, nitrate nitrogen (mg/kg); NH4+-N, ammonium nitrogen (mg/kg); ORP, oxidation–reduction potential (mV).
