Saturated Soil Hydraulic Conductivity is not Constant But Varies with the Time It is Measured

open access: yesGuan'gai paishui xuebao, 2021
【Background and objective】 Saturated soil hydraulic conductivity (KS) is an important parameter characterizing the ability of soil to conduct water. It is often assumed to depend on soil structure and is hence constant for a given soil.

Deriving regional pedotransfer functions to estimate soil bulk density in Austria

open access: yesDie 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

Soil Structure under Forest and Pasture Land-Uses Affecting Compressive Behavior and Air Permeability in a Subtropical Soil

open access: yesSoil Systems, 2022
Machinery traffic and animal trampling can deform the soil and, consequently, impair soil pore functioning. This study aimed to evaluate how soil structure affects the compressibility, physical properties and air permeability of a Typic Paleudalf under ...

A procedure for determining the minimum bulk density of soils [PDF]

open access: yesSouth African Journal of Plant and Soil, 2001
The purpose of this study was to establish a procedure and develop equipment for determining the minimum bulk density of soils. Six soils with silt-plus-clay contents varying between 8 and 41% were selected. The determination consisted of pouring the soil samples into moulds 100 mm high with 106 and 158 mm diameters from three different falling heights,
