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

Scientia 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 ...

Porosity of tropical soils for subgrade of urban roads

Geotecnia, 2022
Nowadays, floods can occur in large urban centers. Consequently, it is necessary to reduce the flow of surface water. A promising solution would be the use of permeable pavements. This article studies the influence that the water infiltrated by a permeable pavement without drainage system would have on the subgrade surface layer of porous lateritic ...

Physical-hydric attributes in areas under forest-pasture conversion in southern Amazon, Brazil

Biotechnologie, Agronomie, Société et Environnement
Description of the subject. The increasing occupation and exploitation of the Amazon has resulted in the increased conversion of forest areas into agricultural land or pasture. This often has negative impacts on soil and water dynamics.

Structural differences between bulk and rhizosphere soil

, 2005
The physical characteristics of the soil at the root–soil interface are crucial because they determine both physical aspects of root function such as water and nutrient uptake and the microbial activity that is most relevant to root growth.

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.

Soil Compaction on Forest Soils from Different Kinds of Tires and tracks and Possibility of Accurate Estimate

Croatian Journal of Forest Engineering, 2008
An 8-WD forwarder loaded with 9,520 kg of timber, and fitted with low or high tire pressures, or tires rounded with tracks, was repeatedly driven on soil for 1, 8 and 24 passes to investigate mechanistic influences on soil compaction.

Research on the Influence of Floods on the Physical Characteristics of Soil

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science
The paper presents research on the influence of floods in the hydrographic basin of Siret River, on the soil. Soil moisture and porosity were determined to observe the influence of excess water in the floodplain area, where the soil is marshy, on the ...
