Variation of Oriental Oak (Quercus variabilis) Leaf δ13C across Temperate and Subtropical China: Spatial Patterns and Sensitivity to Precipitation [PDF]

, 2015
The concentration of the carbon-13 isotope (leaf δ13C) in leaves is negatively correlated with the mean annual precipitation (MAP) atlarge geographical scales.

Entisol Chemical Properties on the System Organic Agriculture

International Journal of Science and Society, 2020
Agricultural systems based on high input energy materials (fossil materials) such as chemical fertilizers and pesticides can damage soil properties and will ultimately reduce soil productivity in the future. Alternative agricultural systems that use low input energy (low input energy) are believed to be able to maintain soil fertility and environmental

Leaf nitrogen and wood density, but not root traits, explain the growth and survival of temperate tree species

Journal of Ecology, Volume 114, Issue 1, January 2026.
The relative importance of different root traits for tree growth and survival may be contingent on the soil environment, so that species' demographic strategies cannot be confidently inferred from below‐ground traits without biotic or abiotic environmental context.

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.

A random forest model for predicting soil properties using Landsat 9 bare soil images

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Digital soil mapping (DSM) provides a low‐cost approach for characterizing the spatial variation in soil properties, which contributes to inconsistent productivity. This study utilized random forest (RF) models to facilitate the DSM of apparent soil electrical conductivity (ECa), cation exchange capacity (CEC), and soil organic matter (SOM) in

Root‐zone enrichment of particulate and nonparticulate organic carbon and nitrogen under grassland management and woodlands across a soil texture gradient in North Carolina, USA

Grassland Research, Volume 4, Issue 4, Page 341-351, December 2025.
Particulate organic carbon and nitrogen are sensitive indicators of long‐term management influence on soil organic matter. A unique calculation method separated pedogenic from management contributions by establishing a baseline at 30‐cm depth in each soil profile.
