Dynamic penetrometers are largely used for studies of soil compaction caused by agricultural practices. In this paper, some critical factors affecting precision, operation time, and ease of use of dynamic penetrometers were evaluated. An alternative procedure recording the number of strikes for pre-defined layers (NL) was proposed and compared to the conventional procedure that records depths per strike (Dn). Mass and falling height variability of commercial penetrometers were assessed and the effects on the penetration resistance (PR) equations were evaluated. Comparisons between dynamic and static penetrometers were performed for soils of different textures and a device to extract dynamic penetrometers from very compacted soils was proposed. The alternative procedure-NL presented no statistical difference to the conventional procedure-Dn, shorter acquisition times and simple data post-processing, which was recommended for routine analysis. Mass and falling height variability of 22 Stolf/IAA penetrometers significantly impacted the equations to calculate PR, with variations from −5 to +10% compared to the standard equation. Thus, users should utilize their own equations to transform raw data in PR. The dynamic penetrometer performance was significantly affected by soil texture as compared to the static penetrometer. The puller device was effective for extracting the dynamic penetrometers from soils with PR higher than 5 MPa.

动态渗透仪主要用于研究由农业实践引起的土壤压实。本文评估了影响动态测深仪精度、操作时间和易用性的一些关键因素。提出了一种记录预定义层（NL）的打击次数的替代程序，并与记录每次打击深度（Dn）的传统程序进行了比较。评估了商业穿透计的质量和下降高度变化，并评估了对穿透阻力 (PR) 方程的影响。对不同质地的土壤进行了动态和静态贯入仪的比较，并提出了一种从非常压实的土壤中提取动态贯入仪的装置。替代程序-NL 与传统程序-Dn 没有统计学差异，更短的采集时间和简单的数据后处理，推荐用于常规分析。22 个 Stolf/IAA 针入度计的质量和下落高度变化显着影响计算 PR 的方程，与标准方程相比变化范围为 -5 至 +10%。因此，用户应该利用他们自己的方程来转换 PR 中的原始数据。与静态贯入仪相比，动态贯入仪性能受到土壤质地的显着影响。拉拔器装置可有效地从 PR 高于 5 MPa 的土壤中提取动态渗透计。与标准方程相比，变化范围为 -5 至 +10%。因此，用户应该利用他们自己的方程来转换 PR 中的原始数据。与静态贯入仪相比，动态贯入仪性能受到土壤质地的显着影响。拉拔器装置可有效地从 PR 高于 5 MPa 的土壤中提取动态渗透计。与标准方程相比，变化范围为 -5 至 +10%。因此，用户应该利用他们自己的方程来转换 PR 中的原始数据。与静态贯入仪相比，动态贯入仪性能受到土壤质地的显着影响。拉拔器装置可有效地从 PR 高于 5 MPa 的土壤中提取动态渗透计。
