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.

Phosphorus Sorption Capacity of Six Iowa Soils Before and After Five Years of Use as Vegetative Treatment Areas [PDF]

open access: yes, 2011
Accumulation of phosphorus in soil is a major factor limiting the operational life of land application waste disposal systems. Moreover, for nutrient management purposes and evaluation of potential environmental problems it is necessary to understand the

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.

Phosphorus Management on ‘Extensive' Organic Farms with Infertile Soils [PDF]

open access: yes, 2007
Two case-study farms with negative P balances maintained acceptable productivity without fertilisers, apparently by ‘mining’ ‘available’ P reserves in surface and subsoil.

Short‐term tillage effects on greenhouse gas emissions and global warming potential from soybean in southeast Arkansas

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Reduced tillage (RT) is a common conservation agriculture practice, generally regarded to be a valuable greenhouse gas (GHG) mitigation approach through increasing soil carbon (C) stocks. However, direct GHG measurements from RT compared to conventional tillage (CT) treatments can vary greatly depending on site‐specific soil properties and ...

Soil‐applied carbon‐based biostimulants differentially affect maize and soybean grain yield and quality

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract The use of carbon‐based biostimulants (e.g., humic acid [HA] and molasses/yeast extract [MYE]) to enhance grain yield and/or quality of maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] is increasing. The objectives of this study were to (1) determine if MYE or HA use can consistently influence grain yield and quality of maize and ...
