Assessing pedotransfer functions to estimate the soil water retention

Bioscience Journal, 2018
Considering the importance of soil water retention for agricultural and environmental purposes, the objective of this study was to assess three pedotransfer functions (PTFs) used to estimate the soil moisture at field capacity (FC) based on soil ...

A PEDOTRANSFER FUNCTION FOR ESTIMATING THE SOIL ERODIBILITY FACTOR IN SICILY

Journal of Agricultural Engineering, 2009
The soil erodibility factor, K, of the Universal Soil Loss Equation (USLE) is a simple descriptor of the soil susceptibility to rill and interrill erosion. The original procedure for determining K needs a knowledge of soil particle size distribution (PSD)

Calibrating the wetting front pressure head of the Green and Ampt infiltration model

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The Green–Ampt (GA) model is a classical analytical solution of the Richards equation used to predict soil water infiltration. Based on a modified form of Darcy's law, it assumes piston‐like flow with a constant pressure head at the soil surface and in the saturated zone, separated from the unsaturated region by a sharp wetting front.

Toward a structured workflow to harmonize soil water content products: A comparative study across different methods

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract This study introduces a structured, multi‐step workflow for harmonizing diverse soil water content (SWC) datasets to improve their meaningful comparability while preserving their intrinsic characteristics. The workflow addresses four components: unit, temporal, vertical, and lateral spatial harmonization, and is applied to point‐scale (PS ...

Do data from the RISMA soil monitoring network support agricultural modeling requirements?

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract The Real‐Time In‐Situ Soil Monitoring for Agriculture (RISMA) network provides soil water and agri‐environmental data for conceptualization, calibration, and validation of remote sensing and modeling products for Canadian agriculture at 32 stations in seven watersheds in Saskatchewan, Manitoba, and Ontario.

Assessing the Relative Roles of Soil Water Potential and Atmospheric Demand on Vegetation Water Stress in Semi‐arid Ecosystems

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Understanding vegetation's response to soil water availability and atmospheric demand is critical for assessing the impact of drought and climate change on semi‐arid ecosystems. However, limited field‐based research has been conducted to assess the relative importance of these drivers on vegetation productivity.

Natural Vegetation Dynamics Confound the Impact of Ecological Restoration on Dryland Hydrology

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Large‐scale ecological restoration (ER) projects have increased shrub and grass cover and growth in arid and semi‐arid regions, but concurrently reduced terrestrial water storage (TWS) through enhanced evapotranspiration (ET). However, the impact of ER on TWS remains unclear due to the confounding effect of natural vegetation dynamics (driven ...

An evaluation of soil retention potential as an important factor of water balance in the landscape

Moravian Geographical Reports, 2016
The ability of soil to retain water in its profile is one of the most important soil functions. It is expressed as the water storage capacity or retention capacity of the soil, and it is primarily affected by the physical properties of the soil.
