Spatiotemporal Droughts Propagation and Direct Driving Variables Under Climate Change Projections: A Case Study of Tunisia

open access: yesInternational Journal of Climatology, Volume 46, Issue 6, May 2026.
Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under

Updating carbon pool initialization within DSSAT‐CENTURY

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Allocation of C to conceptual C pools in the Decision Support System for Agrotechnology Transfer (DSSAT)‐CENTURY model determines the proportion of organic matter available for nutrient cycling. DSSAT‐CENTURY defaults to a pedotransfer function if relevant field history is unknown or a stable C value has not been provided.

A Pedotransfer Function to Map Soil Bulk Density from Limited Data

open access: yes, 2015
Soil bulk density is an important soil parameter directly related to a number of soil properties and processes and required to estimate element stocks in soils on an area basis.

The role of the water regime in a reclaimed limestone quarry

open access: yesJournal of Forest Science
This study focused on the hydrophysical characteristics of an abandoned limestone quarry in Czechia. Six sites were examined; two sites were undergoing natural succession (the Quarry Wall and Reed Canary Grass plots, which had undeveloped arboreal layers)

Introducing a Kriging-based Gaussian Process approach in pedotransfer functions : evaluation for the prediction of soil water retention with temperate and tropical datasets

open access: yes, 2021
Data mining algorithms such as Artificial Neural Networks (ANN) and k-Nearest Neighbour (kNN) have proven their merits in pedotransfer function modelling. Kriging is a well-known algorithm for spatial interpolation, but in this study it is proposed as an

Prediction of soil available phosphorus based on soil organic carbon [PDF]

open access: yes, 2008
There are many cases in which it is desirable to determine relationships among some soil physical and chemical properties. In soil studies, soil available phosphorous (AP) are often determined using laboratory tests, but it may be more suitable and ...

Spatial evaluation of pedotransfer functions using wavelet analysis

open access: yesJournal of Hydrology, 2007
If predictions of pedotransfer functions (PTFs) are distributed in space, then they require a spatial evaluation. Three aspects of performance can be considered in the evaluation of a spatially distributed PTF: (i) the correlation of observed and predicted quantities across different spatial scales; (ii) the reproduction of observed variance across ...

Simulating Soil Moisture Dynamics in a Diversified Cropping System Under Heterogeneous Soil Conditions

open access: yesAgronomy
Agro-ecosystem models are useful tools to assess crop diversification strategies or management adaptations to within-field heterogeneities, but require proper simulation of soil water dynamics, which are crucial for crop growth.
