Summary: This study focused on the cultivated organic soils in Montreal's southwest plain and characterized their physical, chemical, and pedological properties. The maximum peat thickness (MPT) was used as a proxy for soil degradation, and it was found to be moderately related to soil degradation. By dividing the study area into different management zones based on MPT thresholds, spatial differences in soil degradation were observed, highlighting the need for precision agriculture techniques for soil conservation interventions.

Summary: Postshaking settlements of model levees on soft compressible peat during centrifuge tests were compared with numerical solutions, showing that secondary compression is the main contributor to levee settlement and cyclic straining increases secondary compression rate.

Summary: This study analyzed the spatial variability of hydro-physical properties of peat soils and established pedotransfer functions to estimate hydraulic properties. The results show that soil physical and hydraulic properties exhibit different levels of spatial heterogeneity depending on the peat degradation stage.

Summary: Tackling the global carbon deficit through soil organic carbon sequestration in agricultural systems has been a recent focus. However, there is still a lack of comprehensive understanding of on-farm SOC sequestration potentials in order to derive effective strategies.

Summary: Increasing elephant populations result in a loss of tree carbon storage, but contrary to the second hypothesis, soil organic carbon stocks actually increase with higher elephant densities. This increase in SOC is mainly found in the topsoil and is due to the formation of SOC from woody biomass.

Summary: This study provides a new interpretation of pesticide soil standards by introducing average and ceiling legal limits, revealing their implications. It shows that most pesticides can be regulated by both average and ceiling limits. Additionally, a case study on chlorpyrifos soil standards demonstrates that they can protect population health contrary to previous findings.

Summary: This study assessed the effects of different intensity Eucalyptus harvest residue management on soil quality and forest productivity. The results indicated that removing Eucalyptus harvest residues from sandy soils can have adverse impacts on soil quality and forest productivity.

Summary: Monitoring the evolution of soil chemical properties over 20 years revealed that changes in soil management, such as transitioning from rainfed to irrigated model and incorporating organic amendments and crop rotation, can improve soil functions and mitigate soil degradation.

Summary: In this study, nematode diversity in forest soils was found to be mainly influenced by soil organic carbon content, but climatic factors such as temperature, soil phosphorus content, soil pH, and precipitation also played significant roles. Furthermore, there were differences in nematode diversity between different climatic zones. Therefore, high-resolution studies are necessary to accurately predict the response of soil functions when climate conditions exceed the coping range of soil organisms.

Summary: Veterinary antimicrobials (VAs) used in livestock production are excreted in manure, which when applied to agricultural lands increases the risk of contaminating the ecosystem. This review focuses on the sorption mechanisms and transport of VAs in soil, as well as the impact of on-farm management practices.

Summary: This research aimed to determine the effect of agricultural management practices on the total organic carbon (TOC) in the soil in three study locations in the Altos Sur region of Jalisco, Mexico. Results showed significant differences in TOC percentages between the study locations, with recommendations for long-term studies to develop crop management strategies.

Summary: This study used remote sensing data and machine learning models to estimate the soil thickness of cultivated peatlands in the southwestern plain of Montreal. The results showed that the Cubist model performed the best in predicting the depth and thickness. However, the interpretation of the drivers for coprogenous layer thickness was limited by the predictive power of the model.

Summary: Earthworm activity, organic additives, and soil texture are important factors affecting soil aggregate formation, with compost containing active bacteria being the most efficient additive. Earthworm activity promotes aggregate formation, while wet-sieve and laser diffraction methods are comparable for measuring aggregate stability in silty, clayey, and loamy soils.

Summary: A study on the physicochemical properties of agricultural soils in Valle del Cauca (n = 489) found that the saturated hydraulic conductivity (Ks) and electrical conductivity (EC) showed high variability. Soil compaction, nutrients availability, and movement of cations were identified as important factors affecting soil degradation. Soil compaction was observed in 19% of the evaluated sites, while most soils had excellent physicochemical properties, such as organic matter (MO), cation exchange capacity (CEC), and pH.

Summary: Subsurface drainage is commonly used in the Midwest U.S. and can significantly impact soil properties. This study examined the effects of different drainage treatments on soil properties in continuous corn production. The results showed that drainage plus subirrigation increased clay content and accelerated soil organic matter mineralization compared to no drainage and drainage only treatments. Changes in water table conditions also influenced soil properties.

Summary: In the Canadian System of Soil Classification, the classification of soils in the Organic order is primarily based on the dominant organic material in the middle tier. However, there are issues with classifying soils that have predominantly limnic materials. This has implications for agricultural production and crop yields. Therefore, it is proposed to add a new great group called "Limnisol" and further integrate limnic materials into other great groups.
