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

open access: yesJournal 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

open access: yesAdvanced 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.

Evidence for non‐primary macronutrient limitations on cherry yields in young robusta agroforestry systems in the Ecuadorian Amazon

open access: yesAgricultural &Environmental Letters, Volume 10, Issue 2, December 2025.
Abstract Robusta (Coffea canephora Pierre ex Froehner) is a vital cash crop for smallholder farmers in the Ecuadorian Amazon. However, fertility recommendations for robusta production are highly variable across contexts, necessitating regionally tailored recommendations to better diagnose yield‐limiting nutrients. Across a gradient of input intensities

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

open access: yesAgricultural &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.
