The objective of this study was to design, using field data, a filter to correct the soil penetration resistance (PR) values by considering all the effects (penetration friction component [PFC], varying penetration rate, and shocks) that bias PR interpretation. The data used were collected in cultivated peatlands of Montérégie (Canada) known for their advanced state of compaction. Penetration resistance (standard measurements) and cone resistance (CR) measurements (successive measurements per 10‐cm layer) were carried out on four peatlands (five stations per peatland). The filter components, a multi‐resolution analysis (AMR), a polynomial model, and a quantification and removal of PFC were identified and were used to design the filter and tested by cross‐validation. Our study showed that PFC exists (p value < 5%) and does not depend on the peatland on which the measurements are made. An average filter has therefore been designed for the entire site and its effectiveness has been demonstrated. An application to the data collected in 10 fields on the site made it possible to identify the main soil density profiles existing in Montérégie and to quantify the average PFC characterizing these soils. We noticed that, on average, PFC represents between 18.6 and 41% of the PR value. The combined results of the statistical and physical analyses of the filter made it possible to recommend degrees 2 (D2), 3 (D3), and 5 (D5) of the polynomial model to adjust density profiles of cultivated Histosols when there are no, one, or two compact layers.

过滤器，用于校正耕种和压实的组织溶胶中的渗透阻力

这项研究的目的是使用现场数据设计一种过滤器，以通过考虑所有影响PR解释的因素（渗透摩擦分量[PFC]，变化的渗透率和冲击）来校正土壤渗透阻力（PR）值。所使用的数据是在Montérégie（加拿大）的耕地中收集的，这些泥炭地的压实程度很高。在四个泥炭地（每个泥炭地五个站点）上进行了抗渗透性（标准测量）和锥形阻力（CR）测量（每10厘米层的连续测量）。过滤器组件，多分辨率分析（AMR），多项式模型以及PFC的定量和去除被识别出来，并用于设计过滤器并通过交叉验证进行测试。我们的研究表明，PFC存在（p值<5％），并且不依赖于进行测量的泥炭地。因此，为整个站点设计了一个平均过滤器，并证明了其有效性。通过对站点上10个字段中收集的数据的应用，可以确定Montérégie中存在的主要土壤密度剖面，并量化表征这些土壤的平均PFC。我们注意到，PFC平均代表PR值的18.6％至41％。过滤器统计和物理分析的综合结果使得可以推荐多项式模型的2级（D2），3级（D3）和5级（D5），以在不存在时调整培养的组织溶胶的密度分布。 ，或两个紧凑层。
