Tensile strength of aggregates, defined as the force per unit of area required to cause rupture of aggregates, is useful to quantify the effects of both use and management on soil quality. The present study considered the hypothesis that the evaluator’s perception, combined with the force applied to break the aggregate, measured by the TS-Soil device, can be used to define ranges of tensile strength for the degrees of dry soil consistency. The objective in this study was to define ranges of tensile strength for the degrees of dry soil consistency. For this purpose, aggregates (mean diameter of 22 mm after preparation) were collected in five horizons: A and Bi of a Cambissolo Háplico (Cambisol), Bt with a cohesive character of an Argissolo Vermelho Amarelo (Lixisol), Bt of a Luvissolo Crômico (Luvisol) and Bw of a Latossolo Vermelho-Amarelo (Ferralsol). One hundred aggregates of each horizon were evaluated for tensile strength, measured in the TS-Soil device, and, concomitantly, when pressed, were analyzed by an evaluator to assign the following scores to their consistency: 1- loose, 2- soft, 3- slightly hard, 4- hard, 5- very hard, and 6- extremely hard. Data were initially analyzed by descriptive statistics. Then, evaluator’s scores and tensile strength measured by the TS-Soil device were considered to define the ranges of values for the degrees of dry soil consistency. The following tensile strength (kPa) ranges were obtained: >0 to <21 for soft consistency, ≥21 to <38 for slightly hard, ≥38 to <65 for hard, ≥65 to <110 for very hard and ≥110 for extremely hard. It was concluded that the TS-Soil device makes it possible to combine the evaluator’s perception with the force applied to break the aggregate, enabling the definition of ranges of values for the degrees of dry soil consistency, and that the qualitative perception (evaluator) associated with tensile strength values (TS-soil device) gives better quality to the process of evaluating dry soil consistency.

骨料的抗张强度定义为导致骨料破裂所需的每单位面积的力，可用于量化使用和管理对土壤质量的影响。本研究考虑了这样一个假设：评估者的感知力与通过TS-Soil设备测得的破坏​​集料的力相结合，可用于定义抗拉强度范围，以适应干燥土壤的稠度。这项研究的目的是确定干土稠度程度的拉伸强度范围。为此，在五个视野中收集了聚集体（制备后平均直径为22 mm）：CambissoloHáplico（Cambisol）的A和Bi ，具有Argissolo Vermelho Amarelo（Lixisol）的凝聚力的Bt，LuvissoloCrômico（Luvisol）和Latossolo Vermelho-Amarelo的Bw （Ferralsol）。在TS-Soil设备中评估每个视野的一百个骨料的抗张强度，并在评估时，通过评估器进行分析，以为其稠度分配以下得分：1-松散，2-软化，3 -稍微硬，4-硬，5-非常硬和6-非常硬。最初对数据进行描述性统计分析。然后，考虑使用TS-Soil设备测得的评估者得分和抗拉强度来定义干燥土壤稠度的值范围。以下的拉伸强度，得到（千帕）范围：> 0至<21软稠度，≥21至<38为略硬，≥38至<65硬，≥65至<110为非常硬和≥110为极硬。结论是，TS-Soil设备可以将评估者的感知力与破坏骨料的力相结合，从而能够定义干燥土壤稠度程度的值范围，并确定与之相关的定性感知（评估者）具有抗张强度值（TS-土壤设备）的产品可以更好地评估干燥土壤的稠度。
