Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.Abstract Soil microbial biomass (MB) generally exhibits a narrower C:N than soil organic matter (SOM), creating a stoichiometric discrepancy hypothesized to be reconciled in part by C‐ and N‐acquiring enzyme activities. We used soils from an at‐equilibrium long‐term experiment to evaluate the degree to which MB C:N plasticity and enzyme activities ...

Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.Abstract Crop rotational diversity is hypothesized to enhance soil organic carbon (SOC) surface stocks, yet the long‐term SOC response to maize (Zea mays L.)–soybean [Glycine max (L.) Merr.] (MS) relative to continuous maize (MM) is inconsistent despite the greater residue C inputs in MM.

DTPA‐extractable zinc threshold for wheat grain yield response to zinc fertilization in Mollisols
, 2021 Determining soil Zn thresholds for wheat (Triticum aestivum L.) is still challenging since soil Zn tests have been poorly calibrated. Therefore, this work aimed to determine, under field conditions, the DTPA-Zn critical threshold for wheat grain yield ...

Cropping system and nitrogen fertilization modulate soil enzyme kinetics
Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.Abstract The decomposition of soil organic matter and nutrient cycling are largely mediated by extracellular enzymes, yet the effect of soil management on enzyme kinetic (Michaelis constant [Km] and maximum velocity [Vmax]) remains poorly understood.

Changing soil carbon: influencing factors, sequestration strategy and research direction
Carbon Balance and Management, 2020 Soil carbon (C) plays a critical role in the global C cycle and has a profound effect on climate change. To obtain an in-depth and comprehensive understanding of global soil C changes and better manage soil C, all meta-analysis results published during ...

Land Degradation &Development, Volume 37, Issue 14, Page 10355-10370, 30 August 2026.ABSTRACT Although numerous prediction methods have been developed, scientific estimation of the spatiotemporal pattern of soil erosion at the watershed scale remains challenging. In this study, fallout radionuclides of 210Pbex and 137Cs were used to estimate average annual soil erosion and deposition in a Mollisol watershed in Northeast China ...

Decadal effects of fuel treatments and annual grass invasion on sagebrush ecosystem carbon stocks
Ecosphere, Volume 17, Issue 8, August 2026.Abstract Fuel treatments are implemented across large spatial scales in sagebrush (Artemisia spp.) ecosystems of the US Intermountain West to limit wildfire risk and spread, but treatment effects on ecosystem carbon storage remain poorly understood. Fuel treatments can reduce aboveground carbon storage and may also influence belowground carbon storage ...

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.Abstract Measured activities of soil enzymes such as phosphomonoesterase (PHO) can be affected by when and where soils are sampled, and how soils are stored prior to analysis. While these factors have been evaluated individually, simultaneous assessment is needed to determine the relative importance of sampling decisions and sample storage for measured
