Selective sorption of dissolved organic carbon compounds by temperate soils. [PDF]

PLoS ONE, 2012
BACKGROUND: Physico-chemical sorption onto soil minerals is one of the major processes of dissolved organic carbon (OC) stabilization in deeper soils. The interaction of DOC on soil solids is related to the reactivity of soil minerals, the chemistry of ...

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

Journal 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 ...

Reconstructing Mollisol Formation Processes Through Quantified Pedoturbation

Geophysical Research Letters
AbstractMollisols are highly fertile soils and function as significant carbon reservoirs. However, determining their ages and formation processes is challenging due to extensive pedoturbation, which undermines conventional dating methods. Here, we employed luminescence, a light‐sensitive property of minerals widely used in geological dating, to ...

The E4/E6 Absorbance Ratio, Humification Index in Soil and Cereals Drought Tolerance After 26 Years of Fertilisation

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Applying organic fertilisers improves soil health and plant growth by improving the soil organic matter, soil structure, nutrient uptake and water‐holding capacity. Small‐plot stationary field experiments on four different soils in Central Europe evaluate the long‐term effect of organic amendments and/or mineral fertilisers on the soil organic matter ...

Biochar: A Sustainable Solution for Mitigating Greenhouse Gas Emissions and Enhancing Soil Productivity—A Review

Scientifica, Volume 2026, Issue 1, 2026.
Greenhouse gases (GHGs) resulting from human activities significantly impact crop production and agricultural sustainability, necessitating innovative solutions to mitigate their effects. One promising approach is employing biochar for GHG mitigation, providing a potential means to offset emissions and enhance crop productivity sustainably.

Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades

Advanced Science, Volume 12, Issue 47, December 18, 2025.
This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Defining soil‐health targets for root‐zone enrichment of soil organic carbon, nitrogen, and soil‐test biological activity in the southeastern United States

Agricultural &Environmental Letters, Volume 10, Issue 2, December 2025.
Abstract Quantifying soil organic carbon (SOC) and total soil nitrogen (TSN) at a cumulative depth of 0–30 cm under different land use and management scenarios remains a priority, particularly in the southeastern United States, where soil erosion can be intense with high rainfall and long history of intensive soil disturbance.

Comparative study of the mycorrhizal root transcriptomes of wild and cultivated rice in response to the pathogen Magnaporthe oryzae

Rice, 2019
Background Rice, which serves as a staple food for more than half of the world’s population, is very susceptible to the pathogenic fungus, Magnaporthe oryzae. However, common wild rice (Oryza rufipogon), which is the ancestor of Asian cultivated rice (O.
