Deriving regional pedotransfer functions to estimate soil bulk density in Austria

Die Bodenkultur, 2021
Soil bulk density is a required variable for quantifying stocks of elements in soils and is therefore instrumental for the evaluation of land-use related climate change mitigation measures. Our motivation was to derive a set of pedotransfer functions for

Pedotransfer function application for estimation of soil hydrophysical properties using parametric methods

Plant, Soil and Environment, 2007
Soil hydraulic properties are needed as input data to describe and simulate the transport of water and solutes in the soil profile. The most important characteristics are the soil moisture retention curve (SMRC) θ(h) and the hydraulic conductivity ...

Prediction of soil evaporation measured with weighable lysimeters using the FAO Penman–Monteith method in combination with Richards’ equation

Vadose Zone Journal, 2021
Multiannual data (2016–2018) from 12 weighed lysimeters (four soil types with textures ranging from sandy loam to silt loam, three replicates) of the TERENO SOILCan network were used to evaluate if evaporation (E) rates could be predicted from weather ...

Refining pedotransfer functions for estimating peat bulk density [PDF]

Mires and Peat, 2017
Several previous studies have demonstrated the close relationship between peat dry bulk density and gravimetric moisture content. However, the basis for including peat ash (mineral) content or variation in the specific gravity of peat solids has not been

Estimation of the soil water retention curve (SWRC) using pedotransfer functions (PTFs)

Soil and Water Research, 2007
Soil hydraulic characteristics, especially the soil water retention curve and hydraulic conductivity, are essential for many agricultural, environmental, and engineering applications. Their measurement is time-consuming and thus costly.
