High‐Resolution Soil Total Phosphorus Mapping for the Conterminous USA Using Machine Learning

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Accurate estimates of soil total phosphorus (TP) concentrations are essential for sustainable nutrient management, food security, and water quality protection. This study predicts and maps the spatial distribution of TP in the top 5 cm and C horizon of soils across the conterminous USA (CONUS) using data from the Geochemical and Mineralogical ...

Unravelling Subsoil Acidification: Mechanisms, Consequences and Remediation

open access: yesSoil Use and Management, Volume 42, Issue 1, January‐March 2026.
ABSTRACT Subsoil acidification is an intractable agronomic challenge worldwide, and its amelioration is costly and often practically infeasible. Because most studies are confined to the topsoil, acidity development in subsoil commonly remains undetected until it becomes severe.

Systematic Review on the Impact of Climate Change on Soil Properties: Implications for Sustainable Land Management

open access: yesApplied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Climate change significantly affects soil properties, posing challenges for sustainable land management. This review synthesizes recent findings on the impact of climate change rising temperatures, altered precipitation patterns, and an increased frequency of extreme weather events—on key soil attributes, including organic carbon content, pH, bulk ...

Land use and soil characteristics are associated with increased risk of treponeme‐associated hoof disease in elk

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Environments can shape the occurrence and extent of disease outbreaks in wildlife. We studied the effects of environmental features on the occurrence of treponeme‐associated hoof disease (TAHD), an emerging infectious disease of free‐ranging elk (Cervus canadensis), in southwestern Washington, USA.
