Bacterial polyextremotolerant bioemulsifiers from arid soils improve water retention capacity and humidity uptake in sandy soil

open access: yesMicrobial Cell Factories, 2018
Background Water stress is a critical issue for plant growth in arid sandy soils. Here, we aimed to select bacteria producing polyextremotolerant surface-active compounds capable of improving water retention and humidity uptake in sandy soils.

Electrochemical Impedance Spectroscopy of Sandy Soil Containing Cl-, SO42- and HCO3-

open access: yesInternational Journal of Electrochemical Science, 2021
Based on orthogonal experiments, electrochemical impedance spectroscopy was used to study the characteristics of sandy soils containing Cl-, SO42- and HCO3-, and the universality of the equivalent circuit was also studied. The influence of Cl-, SO42- and

An Estimated Correlation between California Bearing Ratio (CBR) with some Soil Parameters of Gypseous Silty Sandy Soils

open access: yesTikrit Journal of Engineering Sciences, 2020
California Bearing Ratio (CBR) value represents the main soil characteristic factor for paving design of flexible pavements & paving of airport sites. It should be used to determine subgrade modulus of crust soil layer, by using certain correlations.

Comparison of indices for the prediction of nitrogen mineralization after destruction of managed grassland [PDF]

open access: yes, 2010
Intensively managed grasslands are occasionally chemically killed with herbicide and ploughed in order to grow an arable crop. After this management, large N mineralization rates with large losses to the environment are commonly observed.

Effects of clayish and sandy soils on the growth of Prosopis argentina and P. alpataco seedlings

open access: yesEcología Austral, 2000
Prosopis alpataco Burk. and P. argentina Phil. occupy areas with different soil characteristics within the arid zone of Argentina. Prosopis alpataco occurs in periodically flooded, clayish and saline soils, whereas P. argentina occurs in non-saline sand

A Rhizogenic Biostimulant Effect on Soil Fertility and Roots Growth of Turfgrass

open access: yesAgronomy, 2021
The excessive use of chemical fertilizers can lead to severe environmental damages. In recent decades, the application of biostimulants to improve soil composition and stimulate plant growth has contributed significantly to environmental preservation. In

Characterization of active layer water contents in the McMurdo Sound region, Antarctica [PDF]

open access: yes, 2010
The liquid soil water contents in the seasonally thawed layer (active layer) were characterized from seven soil climate monitoring sites - four coastal sites from south to north (Minna Bluff, Scott Base, Marble Point and Granite Harbour), and inland ...

Thermal conductivity of a sandy soil [PDF]

open access: yesApplied Thermal Engineering, 2016
The thermal properties of soils are of great importance in many thermo-active ground structures such as energy piles and borehole heat exchangers. In this paper the effect of the porosity and degree of saturation on the thermal conductivity of a sandy soil that has not been previously thermally tested is investigated using steady state experimental ...

Organic matter and biofunctioning in tropical sandy soils and implications for their management [PDF]

open access: yes, 2005
Tropical sandy soils (or upper sandy horizons of tropical soils) have diverse physical and chemical constraints: poor structural stability (making soils sensitive to crusting, and compaction), poor nutrient holding capacity and low cation exchange ...
