An Algebraic Pedotransfer Function to Calculate Standardized in situ Determined Field Capacity [PDF]

, 2016
Despite the large applicability of the field capacity (FC) concept in hydrology and engineering, it presents various ambiguities and inconsistencies due to a lack of methodological procedure standardization.

Using of pedotransfer functions for assessment of hydrolimits [PDF]

Plant, Soil and Environment, 2002
Soil hydrologic coefficients, also called hydrolimits, are soil water contents defined for certain values of water potentials. Closer attention is paid to three hydrolimits: field capacity, point of decreased availability, and wilting point.

Using data assimilation to optimize pedotransfer functions using field-scale in situ soil moisture observations [PDF]

Hydrology and Earth System Sciences, 2021
Soil moisture predictions from land surface models are important in hydrological, ecological, and meteorological applications. In recent years, the availability of wide-area soil moisture measurements has increased, but few studies have combined model ...

Analyzing dual porosity in soil hydraulic properties using soil databases for pedotransfer function development

Vadose Zone Journal, 2022
Current databases of soil hydraulic properties (SHPs) have typically been used to develop pedotransfer functions (PTFs) to estimate water retention [θ(h)] assuming a unimodal pore‐size distribution.

Visible Near-Infrared Spectroscopy and Pedotransfer Function Well Predict Soil Sorption Coefficient of Glyphosate [PDF]

, 2023
The soil sorption coefficient (Kd) of glyphosate mainly controls its transport and fate in the environment. Laboratory-based analysis of Kd is laborious and expensive.

A generally applicable pedotransfer function that estimates field capacity and permanent wilting point from soil texture and bulk density

, 2008
Hydrological models require the determination of fitting parameters that are tedious and time consuming to acquire. A rapid alternative method of estimating the fitting parameters is to use pedotransfer functions.

Controls on Saturated Hydraulic Conductivity in a Degrading Permafrost Peatland Complex

Water Resources Research, 2023
Permafrost peatlands are vulnerable to rapid structural changes under climatic warming, including vertical collapse. Peatland water budgets, and therefore peat hydraulic properties, are important determinants of vegetation and carbon fluxes. Measurements

Determination of the best model for predicting soil available phosphorus based on soil organic carbon

Tikrit Journal for Agricultural Sciences, 2023
There are several methods for determining the determination of soil available phosphorous. These methods require many chemicals and different devices, and determining soil available phosphorous in the laboratory is difficult, time-consuming, and costly ...
