The Podzol and Podzolic Soils

open access: yes, 1961
Publisher Summary This chapter discusses podozol and podzolic soils. The term podzol is applied to the bleached horizon that occurs near the surface of soils in the taiga zone. The word was by no means restricted to soils that were well drained. The appreciation of “illuviation” as an important feature of soils with bleached surface horizons led to ...

Fast High-Resolution pKa Spectrotitrimetry for Quantification of Surface Functional Groups of Retisols

open access: yesSoil Systems
Potentiometric titration in a fast and simultaneously high-resolution modality was proposed for the identification and quantification of protolytic groups of variable strength at the surface of primary soil particles.

Context‐aware UAV LiDAR reveals forest structure and improves tree diameter estimates in subalpine forest

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
In this study we show how, in natural forests, tree heights adapt across environmental gradients as a response to environmental and biotic factors. Awareness of such local adaptations can be encoded into predictive features and leveraged by shallow learning methods to enhance predictions of tree diameter and tree‐level aboveground biomass.

Changes in the Composition of Soil Organic Matter after the Transformation of Natural Beech Stands into Spruce Monoculture

open access: yesSoil Systems
The composition of soil organic matter is considered to have a key influence on C sequestration and global climate change and can be associated with changes in vegetation cover in the terrestrial ecosystem.

Using high‐resolution imagery to map Scots pine regeneration in the Scottish uplands

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
This study utilizes high‐resolution imagery to map over 90,000 naturally regenerating Scots pines across a 3360‐ha area in the Scottish Uplands. Our approach demonstrates that remote sensing can accurately quantify landscape‐scale forest expansion, identifying nearly 85% of saplings over 2 m tall.

Modelling the genesis of equatorial podzols: age and implications for carbon fluxes [PDF]

open access: yesBiogeosciences, 2017
Amazonian podzols store huge amounts of carbon and play a key role in transferring organic matter to the Amazon River. In order to better understand their C dynamics, we modelled the formation of representative Amazonian podzol profiles by constraining ...

Continuous Stem Water Potential Measurements With Microtensiometry Reveal Species Identity and Soil Matric Potential Control of Stem Water Potential in Temperate Forests

open access: yesEcohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Water potential gradients govern water fluxes, and plants respond with species‐specific hydraulic traits that influence ecosystem function. While understanding these traits is key to predicting vegetation responses to climate change, traditional methods like the pressure chamber limit temporal resolution and continuity.

Successful Implementation of Environmental Policy and Governance: Understanding and Modeling Micro Governance

open access: yesEnvironmental Policy and Governance, Volume 36, Issue 2, Page 221-239, April 2026.
ABSTRACT Successful implementation of environmental policy and governance highly depends on the capacity to know about, build new and utilize existing governance structures. However, the theoretical tools and available methods to assess the complexity of emerging or existing structures are rather limited.

Validation of transfer functions predicting Cd and Pb free metal ion activity in soil solution as a function of soil characteristics and reactive metal content. [PDF]

open access: yes, 2007
According to recent insight, the toxicity of metals in soils is better related to the free metal ion (FMI) activity in the soil solution than to the total metal concentration in soil.
