Soil Compaction Due to Agricultural Field Traffic: An Overview of Current Knowledge and Techniques for Compaction Quantification and Mapping [PDF]

open access: yes, 2022
Soil compaction caused by agricultural vehicles is a global problem affecting a considerable proportion of all arable land and causing tremendous costs to farmers and society.

The effect of soil compaction on growth, yield and nitrogen use efficiency of maize in black soil

open access: yesGuan'gai paishui xuebao
【Objective】 Black soil is widely distributed in northeastern China and other countries. Machinery operations in agricultural production in these regions has resulted in soil compaction.

Using small-angle X-ray scattering to investigate the compaction behaviour of a granulated clay [PDF]

open access: yes, 2015
The compaction behaviour of a commercial granulated clay (magnesium aluminium smectite, gMgSm) was investigated using macroscopic pressure-density measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray microtomography (XμT) and ...

Study of the effect of the compaction level on the hydrodynamic properties of loamy sand soil in an agricultural context

open access: yesFrontiers in Water, 2023
Agricultural soil compaction adversely affects crop water use and yield performance and should be avoided or remediated through appropriate soil management strategies.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Soil compaction and soil tillage - studies in agricultural soil mechanics [PDF]

open access: yes, 2004
This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Subsoil Compaction: A hidden form of Soil Sealing in Europe [PDF]

open access: yes, 2001
There are two definitions of ‘soil sealing’: (I) ‘covering (sealing) the soil surface by impervious materials, e.g. concrete, metal, glass, tarmac and plastic’; and (II) ‘changing the nature of the soil such that it behaves as an impermeable medium, e ...

A modeling framework to quantify the effects of compaction on soil water retention and infiltration [PDF]

open access: yes, 2021
The water retention curve (WRC) of arable soils from the southeastern United States at different levels of compaction (no compaction, and 10 and 20% increases in soil bulk density) was estimated using the van Genuchten-Mualem (VG) model.
