Improving the Reliability of Groundwater Recharge Estimates by Modelling Stable Water Isotope Transport in Soils

Hydrological Processes, Volume 40, Issue 7, July 2026.
Three 1‐D unsaturated zone models (HYDRUS‐1D with isotope fractionation) were calibrated with volumetric water content (θ) alone versus θ and δ18O δ2H from soil water. Adding isotopes constrains the parameter spaces and reproduces isotope profiles despite θ extremes, and reveals heterogeneous recharge in semi‐arid Tamil Nadu, South India.

Stratified Data Reconstruction and Spatial Pattern Analyses of Soil Bulk Density in the Northern Grasslands of China

ISPRS International Journal of Geo-Information, 2020
The spatial pattern of soil bulk density in the grasslands of northern China largely remains undefined, which raised uncertainty in understanding and modeling various soil processes in large spatial scale.

A meta‐analysis of soil carbon fraction response to organic amendments in annual croplands

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Organic amendments are key sources of nutrients in croplands and play an important role in maintaining soil organic carbon (SOC) stocks. Stabilization of SOC is mediated by environmental and management factors and may differ between mineral‐associated organic carbon (MAOC) and particulate organic carbon (POC).

Understanding cation exchange capacity through the landscape lens of the Busoga Catena, Uganda

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study identifies the parent material (PM) and examines cation exchange capacity (CEC) across the Busoga catena. In 2022 and 2023, we described 32 pedons and collected 147 samples. Laboratory analyses were particle size analysis, organic carbon (OC) content, pH, and CEC.

Can one‐dimensional infiltration models reproduce soil moisture variations in landslide‐prone hillslopes? Evidence from Petrópolis, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The distribution of soil moisture, resulting from the movement of infiltrated water, plays a fundamental role in the hydrological dynamics of hillslopes and in the triggering of landslides. Although water flow in soils occurs in multiple directions due to combined vertical and lateral fluxes, one‐dimensional (1D) flow models are widely adopted

Pedotransfer functions for estimating the maximum bulk density of major Brazilian agricultural soils: Model comparison and validation

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The Proctor compaction test is the standard method for determining the maximum bulk density (Dbmax) of a soil, a key parameter for obtaining the degree of compaction. However, this method is labor‐intensive and time‐consuming, making it impractical for routine soil quality assessment.
