Analytical modelling of soil porosity and bulk density across the soil organic matter and land-use continuum [PDF]

Scientific Reports, 2022
The thin layer of soil at the earth’s surface supports life, storing water and nutrients for plant uptake. These processes occur in the soil pore space, often half the soil volume, but our understanding of how this volume responds to environmental change

Pedotransfer functions for soil organic carbon stock and soil porosity interpretation in diverse palm oil plantation soils

Sains Tanah: Journal of Soil Science and Agroclimatology
The accurate estimation of soil organic carbon stocks (SOCs) is crucial in sustainable oil palm plantation management. Pedotransfer functions (PTFs) serve as an essential predictive tool for enhancing the interpretation and estimation of soil organic ...

THE VOLUME AND POROSITY OF SOIL CRUMBS

Journal of Soil Science, 1966
Summary A simple and inexpensive apparatus (a test‐tube, burette, and pin) is described for measuring volumes by liquid displacement to an accuracy of greater than 0.5 per cent. This has been adapted to measure soil crumb porosities, ε c

Quantitative Models to Study the Soil Porosity as Function of Soil Resistivity

Open Journal of Modern Hydrology, 2016
Soil degradation is a phenomenon of land subsidence caused by humans. The purpose of this study was to determine the quantitative models of soil porosity. The method used in this research was to measure ground resistance, and determine the value of soil resistivity.

Empirical Model for Estimation of Soil Permeability Based on Soil Texture and Porosity

Jurnal Teknik Pertanian Lampung, 2023
Soil permeability is the ability of the soil to pass water or air. Soil permeability is affected by texture, structure, and soil porosity. This study aims to develop a mathematical model to predict the value of soil permeability as a function of the ...

Influences of Soil Water Content and Porosity on Lightning Electromagnetic Fields and Lightning-Induced Voltages on Overhead Lines

Frontiers in Environmental Science, 2022
This study is performed to analyze the effects of both soil water content and porosity, two of the influencing factors of the finite conductivity, on the propagation of lightning electromagnetic fields (LEMFs) and lightning-induced voltages (LIVs) on ...

Derivation of a macroscopic model for transport of strongly sorbed solutes in the soil using homogenization theory [PDF]

, 2010
In this paper we derive a model for the diffusion of strongly sorbed solutes in soil taking into account diffusion within both the soil fluid phase and the soil particles.
