Enhancing the tree-boosting-based pedotransfer function for saturated hydraulic conductivity using data preprocessing and predictor importance using game theory

open access: yesGeoderma, 2022
Machine learning (ML)-based pedotransfer function (PTF) has become a promising alternative to the generic PTFs for predicting the saturated hydraulic conductivity of soils (Ks). This study enhanced the performance of ML-PTF for predicting Ks by utilizing

Development of a New Pedotransfer Function Addressing Limitations in Soil Hydraulic Models and Observations

Water Resources Research, 2022
The most applied pedotransfer functions (PTFs) often suffer from two main limitations: (a) the soil hydraulic models (SHMs) only account for capillary forces and/or the models show an unrealistic decrease near saturation for fine‐textured soils; (b) the ...

Toward Developing a Generalizable Pedotransfer Function for Saturated Hydraulic Conductivity Using Transfer Learning and Predictor Selector Algorithm

Water Resources Research, 2021
Pedotransfer functions (PTFs) are being instrumental in saturated hydraulic conductivity (Ks) estimation. Despite various advancements, the performance of existing generic Ks predicting PTFs need augmentation.

Estimating Soil Particle Density using Visible Near-infrared Spectroscopy and a Simple, Two-compartment Pedotransfer Function

open access: yesSoil Science Society of America Journal, 2019
The average particle density (ρd) is a fundamental soil property, used for calculating the total porosity. Traditional ρd measurement by pycnometer method is tedious and time-consuming.

Glyphosate sorption to soils of Argentina. Estimation of affinity coefficient by pedotransfer function [PDF]

open access: yesGeoderma, 2017
Argentine agricultural production is fundamentally based on a technological package that combines direct seeding and glyphosate with transgenic crops (soybean, maize and cotton), which makes glyphosate the most widely employed herbicide in the country ...

A Saturated Excess Runoff Pedotransfer Function for Vegetated Watersheds

open access: yes, 2013
Since Hewlett and Hibbert's publication in 1967, there has been a slow recognition that saturated excess runoff is the main runoff mechanism in vegetated watersheds.

Reduce uncertainty in soil hydrological modeling: A comparison of soil hydraulic parameters generated by random sampling and pedotransfer function

open access: yesJournal of Hydrology, 2023
Numerical simulation of unsaturated soil hydrology relies on calibrated soil hydraulic parameters, which are subject to uncertainty due to imperfect information during the inverse modelling. This study investigates the effectiveness of reducing parameter
