“…Moreover, this method effectively solves the shortcomings of the fuzzy underground structures and uncertain levels encountered in previous studies, and it can gradually be extended to farmland soil thickness detection based on this study. In recent years, GPR has gradually been applied to the non-destructive and rapid acquisition of the SWC [28,55]. Therefore, some research has been conducted on the acquisition of the water content of the cultivated layer while studying the identification of the TCS.…”

Rapid, accurate, and non-destructive monitoring after land reclamation is the basis of and key to realizing land restoration evaluation, as well as land use direction decision-making and improvement. However, the biggest problem with the filling reclamation method is the poor soil water retention caused by the insufficient thickness of covering soil (TCS), which results in the loss of soil nutrients. In addition, the cost of filling reclamation has also increased due to the excessive TCS. In this study, multi-source remote sensing data acquisition methods were used to assess the impacts of the TCS of the filling reclamation method on soil water retention and crop growth (CG). We found that as the TCS increases, the overall trend of the CG gradually increases, and the overall trend of the soil water content slowly increases. However, considering the huge economic costs and the cost of soil sources, we suggest that the optimal TCS for the filling reclamation method should be controlled within 40-50 cm. The results of this study provide a reference for the use of multi-source remote sensing technology for rapid evaluation of the restoration effects of reclaimed areas and for the rational utilization of coal chemical wastes.

“…Generally, stressed trees are more susceptible to attacks by insects than their healthy counterparts [47]. Since white birch shows little tolerance to flooding [48], the trees in the wind-shelter belts might be stressed with age due to relatively high ground water level in the drained peatland [49]. This may increase the susceptibility to white-spotted longicorn beetle.…”

A widespread decline of white birch (Betula platyphylla var. japonica) shelterbelts was observed in central Hokkaido, Japan. Many exit holes bored by white-spotted longicorn beetles (Anoplophora malasiaca) were found at the base of the trunks of trees in these stands. The present study aims to evaluate the effects of infestation on the degradation, and demonstrates whether the number of exit holes (Nholes) can be used as an index of the decline of trees. We selected 35 healthy appearing stands and 16 degraded stands in the study area. A generalized linear mixed model with zero inflation revealed that Nholes of standing dead trees tended to be greater than that of living trees, and the tree vigor decreased with increasing Nholes. These results implied that the degradation of the shelterbelts was caused by the beetle. We also found size-dependent mortality, i.e., only a few larvae can cause the death of smaller trees, but not larger trees. Furthermore, evaluation of the degradation at the stand level (Nholes) using a logistic regression analysis revealed that the degradation at the stand level could be predicted by Nholes. Our findings can be used as a useful index marker for diagnosing white birch shelterbelts.

“…Soil compaction is a significant determinant of plants' plant growth and mortality rates (Hattori et al, 2013). Furthermore, it can provide a fundamental component that indicates land degradation as it reflects the productivity of the land areas (Iwasaki et al, 2020). Overuse of heavy machinery, intensive cropping, short crop rotations, intensive grazing and inappropriate soil management will lead to compaction (Adnan et al, 2017).…”

In-situ soil assessment such as field soil compaction can often be a helpful approach in help determining soil suitability for certain crops. In this study, an assessment was conducted to characterize the Soil Penetration Resistance (SPR) in planted sago palm (Metroxylon spp.) plantation at different growth of rosette and trunking stages under mineral soils ecosystem. SPR in-situ assessment would provide a beneficial guideline and site indicator in determining land suitability before establishing sago plantations, especially on mineral soils. The study was conducted in Mukah, Sarawak, with two study sites at Oya and Talau. The growth stage of sago palm at Oya and Talau site were at the rosette and trunking stage, respectively. The soil types at both study sites consisted of Gley soils (clayey) with significant mineral development at the subsoil horizon. SPR measurements were taken using a Hasegawa-type cone penetrometer. Soil compaction in SSSED Oya was more compact than Talau river research station from shallow depth to subsurface soils. SPR at SSSED Oya ranged between 7.5 to 46.8 J cm-1, while Talau river research station ranged between 1.9 J cm -1 to 11.1 J cm -1 . Although there was a significant difference between the growth stage of 0-20 cm and 80-100 cm soils depths, both SSSED Oya and Talau river research station are considered suitable areas for sago palm plantations. Using a practical and convenient approach in assessing soil suitability for sago cultivation, SPR assessment to identify potential areas for the establishment of sago cultivation area can be the fundamental tools for landowners in preparing their land for future cultivation.
