“…According to [34], the weak spatial dependence is related to the external factors (e.g., soil tillage and agricultural machinery traffic), while the well-defined spatial dependence is more related to intrinsic factors associated with the natural soil structure. In other similar studies [24,26,44], the authors found spatial dependence of PR in areas under eucalyptus production. However, in these studies, the PR readings were carried out in eucalyptus stands before harvesting and soil tillage.…”

“…However, in these studies, the PR readings were carried out in eucalyptus stands before harvesting and soil tillage. Even under these conditions, [26] also observed a decrease in the PR spatial dependence from the bottom to the soil's top layer. In the present study, the geospatial assessment allowed inferences about the spatial distribution of the PR measured after soil tillage.…”

“…Additionally, the geospatial evaluation of PR can allow the identification of compacted sites for specific management operations [23,24]. Such detailed PR information can improve soil physical quality evaluation in mechanized planted forest areas [24][25][26].…”

This study aimed to evaluate the impacts of mechanized harvesting and soil tillage on soil penetration resistance (PR), influenced by the eucalypt straw management under sandy clay Oxisol in Southern Brazil. The study was conducted in a eucalyptus production area under Oxisol in Paraná State, Brazil. The treatments consisted of two harvesting systems: harvester + forwarder (HF) and feller + skidder (FS) both applied in areas under coppicing and stand renewal eucalypt cultivation systems. For stand renewal areas, eucalypt straw was managed on the soil surface at levels of 100, 50, and 0% before soil tillage. PR and soil moisture measurements were made in points distributed in regular grid for all treatments. This grid also was used to evaluate the geospatial behavior of PR in the stand renewal areas. During the measuring of PR, the averages (± confidence interval) of soil moisture up to 0–0.60 m depth were 0.20 ± 0.01 and 0.24 ± 0.01 in coppicing and stand renewal areas, respectively. In areas under coppicing, the PR mean ± confidence interval at 0–0.05 m layer in HF (1.28 ± 0.24 MPa) was lower than in FS treatment (2.11 ± 0.44 MPa). However, the PR values were similar between treatments in stand renewal areas, regardless of the forest straw level on the soil surface. For both harvesting systems, there was a lack of spatial dependence of PR up to 0.40 m soil depth, indicating some physical and mechanical homogenization induced by the soil tillage in the layer. Eucalypt straw contributed to mitigating effects of harvest traffic on PR level in coppicing forest systems. However, different levels of eucalypt straw managed before soil tillage did not influence PR levels in stand renewal forest systems.
