Vegetation effects on soil pore structure and hydraulic properties in volcanic ash soils of the high Andes
(2022)
Soil hydraulic properties control the provision of hydrological services. Vegetationand topography influence these properties by altering soil structure and porosity. Theunderlying mechanisms are not yet fully understood ...
FRACTAL CHARACTERISTICS OF THE HORIZONTAL MOVEMENT OF WATER IN SOILS
(World Scientific Publ Co Pte Ltd, 1994-09-01)
Observed deviations from traditional concepts of soil-water movement are considered in terms of fractals. A connection is made between this movement and a Brownian motion, a random and self-affine type of fractal, to account ...

Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
(Elsevier Science, 2015-12)
Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ...

Espaço poroso avaliado por tomografia e propriedades hídricas e mecânicas em solos argilosos sob culturas anuais e campo natural
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2020-07-16)
The growing demand for food and energy causes an intensification in agriculture, which uses
larger machines and results in high pressures applied to the soil. As the pressures increases there
are changes in the soil ...
Autonomous Soil Water Content Sensors Based on Bipolar Transistors Encapsulated in Porous Ceramic Blocks
(Mdpi, 2019-03-22)
We present an autonomous sensor to measure soil water content that uses a single heat pulse probe based on a transistor encapsulated in a porous block. The sensor uses a bipolar junction transistor, which performs as both ...
A influência da saturação pós-compactação no comportamento resiliente de dois solos do Rio Grande do Sul empregados em subleito rodoviário
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-12-16)
Aiming to correct one of the predominant defects on brazilian pavements, the fatigue cracking, the National Dimensioning Method was developed, extinguishing the empirical approach applied to highways so far. The new method ...
