Soil health metric values may vary across soil types and even within the same soil series under different management systems. The goal of this study was to determine the amount of variation present in Cecil sandy loam soils (fine, kaolinitic, thermic Typic Kanhapludults) under row crop and hay management systems via field (single‐ring infiltration, Cornell Sprinkle Infiltrometer, and a farmer score card) and laboratory soil health metrics [soil respiration, phospholipid fatty acid (PLFA) analysis, permanganate‐oxidizable C (POXC), β‐glucosidase, β‐glucosaminidase, alkaline and acid phosphatase, arylsulfatase, phosphodiesterase, soil organic C (SOC), total N (TN), autoclave citrate‐extractable (ACE) protein content, aggregate stability, mean weight diameter, and bulk density]. Soil samples were collected in three hay and three crop fields. ANOVA indicated significant variations between systems, with depth and interactions among system, field, and/or slope position, depending on the metric (p < 0.05). Infiltration measurements were highly variable and the measurement methods produced inconsistent values. The majority of laboratory metrics significantly decreased with depth. Soil respiration was significantly different between systems (crop > hay), whereas arylsulfatase, acid phosphatase, β‐glucosidase, β‐glucosaminidase, ACE, POXC, and aggregate stability had significant system × depth interactions (0–5 cm hay > crop) and POXC had a significant system × pedon interaction. Enzyme assays, PLFA measurements, POXC, TN, SOC, and ACE protein content were also significantly correlated with each other. Unexpected trends and variable results suggest that more data should be collected before effective soil health metrics and baseline values can be established.

北卡罗莱纳州皮埃蒙特塞西尔土壤的土壤健康指标比较

土壤健康指标值可能会因土壤类型而异，甚至在不同管理系统下的同一土壤系列中也可能不同。这项研究的目的是通过田间（单环渗入，康奈尔洒水渗入仪和农民评分）确定行作物和干草管理系统下塞西尔沙质壤土（精细，高岭土，热型典型北汉普达特）中存在的变异量。卡）和实验室土壤健康指标[土壤呼吸，磷脂脂肪酸（PLFA）分析，高锰酸盐可氧化C（POXC），β-葡糖苷酶，β-葡糖胺酶，碱性和酸性磷酸酶，芳基硫酸酯酶，磷酸二酯酶，土壤有机碳（SOC） ，总氮（TN），可高压灭菌的柠檬酸盐提取（ACE）蛋白含量，聚集体稳定性，平均重量直径和堆积密度]。在三个干草和三个农田中收集了土壤样品。p  ＜0.05）。渗透测量值变化很大，测量方法产生的值不一致。大多数实验室指标随深度显着降低。不同系统之间的土壤呼吸差异显着（作物>干草），而芳基硫酸酯酶，酸性磷酸酶，β-葡萄糖苷酶，β-葡萄糖酰胺酶，ACE，POXC和集聚稳定性具有显着的系统×深度相互作用（0-5 cm干草>作物）和POXC具有显着的系统×人机交互作用。酶测定，PLFA测量，POXC，TN，SOC和ACE蛋白含量也显着相关。出乎意料的趋势和变化的结果表明，在可以建立有效的土壤健康指标和基准值之前，应收集更多的数据。
