Heavy Metals in Soils: An Investigation of the Contaminated Floodplains Around the Sinu River, Colombia. [PDF]

Geohealth
Abstract Heavy metal contamination in rivers mostly originates from anthropogenic sources such as industrial activities, mining, agriculture, and urban runoff. These metals accumulate in river sediments and impact living organisms and the surrounding ecosystem. Historically, some rivers in Colombia have faced issues related to heavy metal contamination,

Wet Season Environments Drive Local Adaptation in the Timber Tree Dicorynia guianensis in French Guiana. [PDF]

Mol Ecol
ABSTRACT The vast tropical rainforests of the Guiana Shield in Northern South America play a vital role in maintaining the region's ecological balance and economy. Increasing pressure from selective logging, gold mining and climate variability threatens these ecosystems. Sustainable rainforest management requires understanding the genetic diversity and

The German Soil Systematics and the Rationale Behind Its Revision

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Understanding cation exchange capacity through the landscape lens of the Busoga Catena, Uganda

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study identifies the parent material (PM) and examines cation exchange capacity (CEC) across the Busoga catena. In 2022 and 2023, we described 32 pedons and collected 147 samples. Laboratory analyses were particle size analysis, organic carbon (OC) content, pH, and CEC.

Pedogeomorphology of semiarid soils of Ulu Peninsula, James Ross Island, Antarctica

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Located in a transitional climatic zone of the Antarctic continent, James Ross Island (JRI) presents soils that reflect complex interactions between lithology, topography, and pedogenesis. This study characterizes soils along a toposequence to evaluate how slope position and parent material control soil properties and weathering patterns in a ...

Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Soil waters are a central component of the terrestrial water cycle. Their δ2H, δ18O, and d‐excess values contain rich information about hydroclimate, including the source of moisture and its evaporative history. Paleoclimate workers seek to investigate ancient hydroclimates via triple oxygen isotope geochemistry, termed Δ′17O, which is ...

Soil Diversity and Climate: An Overview of Profile Data and Acquisition With the WoSIS Global Legacy Dataset

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT Soil profiles are the primary field evidence from which pedogenesis, soil classification and land‐use effects are interpreted, yet their availability remains uneven across climates and land‐cover contexts. Here, we analyse the World Soil Information Service (WoSIS) 2023 snapshot together with Copernicus Global Land Cover 2015 and the global ...

Toward a Unified Soil–Bedrock Continuum: Building a Systems Understanding

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT Soil is the foundation of life itself, and without healthy soils our day‐to‐day lives would be forever changed. A significant proportion of soil science focuses on the topsoil, overlooking much of the soil profile. If soil science is to fully serve society, we must expand our understanding to the full soil–bedrock continuum, extending beyond ...

Spatial Variation of Acidic Sodic Soils in High‐Andean Environments and Theoretical Estimation of Gypsum Requirement

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT High‐Andean forage systems are characterized by extensive management of cultivated forages, primarily through rotation of forage oats (Avena sativa) and alfalfa (Medicago sativa), under marginal edaphoclimatic conditions. Within this context, soil sodicity severely constrains the productivity of these systems in the districts of Ayaviri and ...

Integrating Soil Taxonomy With Soil and Remote Sensing Indices for Site‐Specific Management in the Egyptian Nile Delta Fringes

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT Sustainable soil management in arid regions is constrained by the limited translation of subgroup‐level soil taxonomy into site‐specific agronomic recommendations. Hence, this study integrated field observations and laboratory analyses from 18 soil profiles with freely available Google Earth Engine (GEE) datasets.
