Software for micromorphometric characterization of soil pores obtained from 2-D image analysis

open access: yesScientia Agricola, 2016
Studies of soil porosity through image analysis are important to an understanding of how the soil functions. However, the lack of a simplified methodology for the quantification of the shape, number, and size of soil pores has limited the use of ...

Porous materials in building energy technologies—a review of the applications, modelling and experiments [PDF]

open access: yes, 2018
Improving energy efficiency in buildings is central to achieving the goals set by Paris agreement in 2015, as it reduces the energy consumption and consequently the emission of greenhouse gases without jeopardising human comfort.

Soil structure and earthworm activity under different tillage systems in organic farming [PDF]

open access: yes, 2007
Organic farmers are encouraged to adopt conservation tillage to preserve soil quality and fertility and prevent erosion. However, many studies in different soil and climate conditions have demonstrated that the compaction of the untilled layer is higher ...

Simulating microbial degradation of organic matter in a simple porous system using the 3-D diffusion-based model MOSAIC [PDF]

open access: yes, 2013
This paper deals with the simulation of microbial degradation of organic matter in soil within the pore space at a microscopic scale. Pore space was analysed with micro-computed tomography and described using a sphere network coming from a geometrical ...

Grass Clippings Mulching Improves Infiltrability of Low-Permeability Dryland Soils

open access: yesAir, Soil and Water Research
In arid and semiarid regions, the high compactness and poor water permeability of the soils severely limit agricultural production. This study aims to shed light on techniques to enhance the permeability of these soils—specifically, by improving soil ...
