Mechanical Soil Database—Part I: Impact of Bulk Density and Organic Matter on Precompression Stress and Consequences for Saturated Hydraulic Conductivity

open access: yesFrontiers in Environmental Science, 2022
The mechanical strength of agricultural soils depends on many soil properties and functions. The database, “soil strength and consequences for sustainable land use and soil management SOILMECHDAT-Kiel”, originates from the “Horn Research Group” includes ...

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 ...

Compressibility of a Cambisol Submitted to Periods of Rotational Grazing and Strategies to Avoid Additional Soil Compaction

open access: yesConservation, 2023
Soil compaction is one of the main causes of soil degradation, and some parameters have been used to characterize it, like those related to compressibility and the degree of compactness.

Prediction of geotechnical properties of deltaic clays by using regression analysis models [PDF]

open access: yesEgyptian Journal of Pure and Applied Science, 2022
Establishment of any engineering structure on a compressible clay leads to settlement and/or failure through this clay. The amount of settlement is related mainly to the compressibility parameters while the failure to the undrained strength.

Spatial variability of precompression stress and volumetric water content of a red-yellow latosol (Oxisol)

open access: yesBioscience Journal, 2020
The intensive agricultural machinery traffic to which soils under coffee crops are exposed may cause significant changes in soil structure. The goals of this study were to: a) characterize the spatial variability of precompression stress (σp) and ...

Estimation of precompression stress in an Ultisol cultivated with sugarcane

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2019
Compressive soil properties are typically used for the understanding of compaction process. As an alternative to laboratory tests, pedo-transfer functions have been used to estimate the mechanical behaviour of soil as a function of soil physical ...
