Relative soil water content as a factor for wind erodibility in soils with different texture and aggregation
(Elsevier, 2019-02)
The soil water content is one of the main factors influencing the beginning of soil particle movement by the wind. Although, some authors studied the effect of soil water content on threshold wind velocity and have defined ...
The Flat Dilatometer Test in an Unsaturated Tropical Soil Site
(2021-01-01)
The site characterization of unsaturated soils is well stablished based on laboratory tests, which are expensive and time-consuming. In-situ testing methods, such as the flat dilatometer test (DMT), are an alternative to ...
Root volume and dry matter of peanut plants as a function of soil bulk density and soil water stress
(2008-04-01)
Soil compaction may be defined as the pressing of soil to make it denser. Soil compaction makes the soil denser, decreases permeability of gas and water exchange as well as alterations in thermal relations, and increases ...

Deep Soil Water Content and Forage Production in a Tropical Agroforestry System
(2022-03-01)
Agroforestry systems integrating tree and forage growth are important for maintaining soil health but may change the soil’s physical-hydric properties. Our goal was to investigate the impact of introducing Eucalyptus trees ...
Corn root length density and root diameter as affected by soil compaction and soil water content
(2007-01-01)
Negative effects of soil compaction have been recognized as one of the problems restricting the root system and consequently impairing yields, especially in the Southern Coastal Plain of the USA. Simulations of the root ...

Soil volumetric changes in natric soils caused by air entrapment following seasonal ponding and water table rises
(Elsevier Science, 2001-11)
Soil volumetric changes have been seldom studied in seasonally ponded soils subjected to periodic water table rises. In the Flooding Pampa of Argentina the topsoils develop significant swelling and shrinkage, despite their ...
Strength and Stiffness Parameters of an Unsaturated Tropical Soil
(Amer Soc Civil Engineers, 2018-01-01)
The interpretation of in-situ tests for site characterization of unsaturated tropical soil sites should consider both the spatial and the seasonal variability caused by the soil suction on the strength and stiffness ...
Water table effects on bean yield and nitrate distribution in the soil profile
(2008-07-01)
In order to evaluate the bean yield under different water table levels as well as the moisture and nitrate distribution in the soil profile, a field experiment was carried out in the experimental area of the College of ...
