Characteristics of soil samples in monocropping and intercropping systems with different fertilization treatments. CK, plots without fertilizer added; CF_I, plots with 60 kg N ha-1 of urea; CF_II, plots with 120 kg N ha-1 of urea; OF_I, plots with sheep manure (0.035% N, equals 60 kg N ha-1 year-1); OF_II, plots with sheep manure (0.035% N, equals 120 kg N ha-1 year-1)..Different lowcase letters denote significant differences between treatment at the 0.05 probability level on the basis of Kruskal-Wallis tests corrected for multiple testing. Soil nutrients include total Carbon (TC), total nitrogen (TN), dissolved organic nitrogen (DON), dissolved organic carbon (DOC), nitrate (NO3--N), ammonium (NH4+-N), soil available phosphorus (AP), soil available potassium (AK), soil total phosphorus (TP), soil total potassium (AK), microbial biomass carbon (MBC) and nitrogen (MBN).
