Summary: The existing method for assessing phosphorus release risk from well-drained soils underestimates the risk in poorly-drained soils, indicating the need for specific risk assessment tools.

Summary: Cypress domes, characterized by cypress trees and other subdominant species, are declining due to changes in land use and climate. This study found that the structure of cypress dome tree communities is correlated with hydroperiod and water depth, and wetland tree recruitment is affected by altered hydroperiods and water depths.

Summary: This study utilized Sentinel-1 coherence maps to map the wetland hydroperiod in the entire province of Alberta, Canada. The results showed that a coherence value of 0.45 was the optimum threshold to distinguish flooded and non-flooded wetlands. Most wetlands were inundated less than 50% of the time, with around 40% being seasonally inundated and approximately 5% never being flooded. The study demonstrated the high capability of InSAR coherence products for wetland hydroperiod analysis and provided suggestions for future improvements.

Summary: Soil bulk density (BD) is an important physical parameter for soil quality control and calculation of soil organic carbon (SOC) stock. However, laboratory analysis of BD is time-consuming and expensive, making it difficult for national-scale soil assessments. This study used chemometric and machine learning algorithms to estimate BD in Irish soil based on MIR spectral libraries. The best performance was achieved with a SVM model, which had a RPIQ of 3.61, R2 value of 0.81, and RMSEP of 0.132. The spectral soil BD model outperformed traditional pedo-transfer functions overall and showed similar accuracy for the A horizon but improved performance for other horizons.

Summary: The study reveals that in arable soils, P, Fe2+, and OC mobilize at E-H <= 200 mV, while P immobilizes at E-H > 200 mV due to strong binding with Fe3+. Additionally, pH changes and interactions with Fe3+, organic carbon, and carbonates play a key role in the migration and retention of P during redox processes.

Summary: In hardwood floodplain forests, significant relationships exist between soil organic carbon (SOC) stocks and hydromorphic features, soil texture, C/N ratio, pH, and forest age. The complexity of interactions among heterogeneous microrelief, anthropogenic effects, and hydrologic situation make it challenging to predict SOC stocks accurately without field validation. Profiling the controlling factors for SOC storage in these environments suggests that relief and sedimentation proxies are the strongest factors influencing SOC stocks, while vegetation plays a subordinate role.

Summary: This study examines the ability of Phragmites australis Cav. to indicate soil pollution with heavy metals (HMs) and priority polycyclic aromatic hydrocarbons (PAHs) through changes in the plant's ultrastructure. The results show that the concentrations of HMs and PAHs increase as the distance from the power station decreases and the direction of the prevailing wind (northwest) is approached. The highest concentrations of pollutants are found in the roots of the plants. The study also reveals changes in the ultrastructure of chloroplasts in P. australis affected by the accumulation of HMs and PAHs. The most severe damage to the cellular organelles is observed in plants located within 2.5 km from the emissions source and in the direction of the predominant wind.

Summary: The South African National Wetlands Map version 5 shows 87% more extent of wetlands compared to the Global Surface Water products. Both South African and global statistics indicate a decreasing trend in the extent of wetlands, particularly in lacustrine wetlands. Further investigation is needed to confirm these trends in relation to decadal drought periods.

Summary: The production of waste by mining companies poses a complex environmental challenge, and constructing Technosols from mining waste could be a viable solution. However, there is a lack of knowledge about the soil formation processes that govern the functioning of these Technosols. This study analyzed the pedogenic processes in Technosols formed unintentionally from Fe-rich tailings deposited in a river estuary after a mining disaster, providing valuable insights into the factors influencing Technosol formation and functioning.

Summary: The study developed a system for determining loose and tapped bulk density through measuring material volume during tapping compaction, exploring the effects of number, frequency, and amplitude on tapped bulk density, and evaluating material flowability. Tapped bulk density increases with the number of taps, but the increase in frequency and amplitude leads to a subsequent reduction in the response variable.

Summary: An improved explosive consolidation device was used to fabricate bulk nano-aluminum materials with high density, hardness, and strength. By adjusting the detonation velocity, the production of Mach holes was reduced, resulting in aluminum with uniform microstructure and a grain size of 80 nm. The explosively consolidated aluminum had four times the hardness and double the compressive strength compared to industrially prepared aluminum.

Summary: Traffic-induced soil compaction in the field has become an important constraint to sustainable agricultural development. This study found that tractors with small axle-loads generate higher soil additional stress at 0-20 cm depth, while tractors with large axle-loads generate higher soil additional stress at 20-80 cm depth. The compaction by different levels of tractor load inhibited key growth indicators of maize, resulting in yield reductions.

Summary: The study evaluated the natural recovery of soil physical attributes in a clayey Oxisol under different intensities of dairy cattle grazing in southern Brazil. It was found that increased grazing intensity negatively affected soil physical quality, but increases in total porosity and macroporosity were observed 90 days after grazing exclusion.

Summary: The degradation of soil in the UK is affecting ecosystem services, particularly water flow regulation. This pilot study found that changes in livestock management, such as mixed sheep and cattle grazing, can lead to rapid improvements in soil physical properties, potentially enhancing soil health and water flow regulation on grazed land in the UK.

Summary: This study presents a novel procedure and mathematical model using four artificial intelligence algorithms to predict the cumulative degree of soil compaction during dynamic compaction. The AI models, including ANN, SVR, GBM, and RF, show high prediction metrics with accuracy. The best-performing model, ANN, is utilized to develop a new mathematical model for CDSC prediction.
