Soil chemical properties at 15–30 cm depth from spring of 2012 influenced by different treatments that included tillage treatments: No-tillage (NT); shallow tillage (ST), deep tillage every other year (DT-2); deep tillage once at the initiation of the experiment (DT-6); grass (Gr); and grass + legume (Gr + L) mixtures under different amendments: Chemical fertilizer at high rate (HF) and low rate (LF); beef manure at high rate (HM) and low rate (LM); and no nitrogen added, control (0N).

本数据集包含2012年春季采集的15~30厘米土层土壤化学性质数据，相关数据受多组处理的影响，处理类型涵盖：耕作处理（免耕（No-tillage, NT）、浅耕（Shallow Tillage, ST）、隔年深耕（Deep Tillage Every Other Year, DT-2）、实验启动时一次性深耕（Deep Tillage Once at Experiment Initiation, DT-6））、单播草地（Grass, Gr）以及禾草-豆科混播草地（Grass + Legume Mixtures, Gr+L）；所有上述处理均配套不同的土壤改良施肥措施：高用量化肥（High-rate Chemical Fertilizer, HF）、低用量化肥（Low-rate Chemical Fertilizer, LF）、高用量肉牛粪肥（High-rate Beef Manure, HM）、低用量肉牛粪肥（Low-rate Beef Manure, LM）以及无氮添加对照组（0N Control, 0N）。
