Droplet infiltration dynamics and soil wettability related to soil organic matter of soil aggregate coatings and interiors

Journal of Hydrology and Hydromechanics, 2016
The organo-mineral coatings of soil aggregates, cracks, and biopores control sorption and macropore-matrix exchange during preferential flow, in particular in the clay-illuvial Bt-horizon of Luvisols.

Water stable aggregates of Japanese Andisol as affected by hydrophobicity and drying temperature

Journal of Hydrology and Hydromechanics, 2014
Hydrophobicity is a property of soils that reduces their affinity for water, which may help impeding the pressure build-up within aggregates, and reducing aggregate disruption.

Mildly hydrophobic biobased mulch: A sustainable approach to controlling bare soil evaporation

Vadose Zone Journal, 2020
Mulching with polyethylene film is the conventional approach to decrease evaporative water loss from agricultural soils, but it is not environmentally sustainable.

Extent and persistence of soil water repellency induced by pines in different geographic regions

Journal of Hydrology and Hydromechanics, 2018
The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions.

Soil hydrophobicity: comparative study of usual determination methods

Ciência Rural, 2015
Hydrophobic or water repellent soils slowly absorb water because of the low wett ability of the soil particles which are coated with hydrophobic organic substances. These pose significant effects on plant growth, water infiltration and retention, surface

Soil water repellency changes with depth and relationship to physical properties within wettable and repellent soil profiles

Journal of Hydrology and Hydromechanics, 2017
This study explored the effect of soil water repellency (SWR) on soil hydrophysical properties with depth. Soils were sampled from two distinctly wettable and water repellent soil profiles at depth increments from 0-60 cm. The soils were selected because

Dynamic contact angle as a new metric for the water repellency evaluation of biochar-amended soil

Biochar
Biochar hydrophobicity is crucial for understanding its interaction with environmental substances (e.g., soil, water, pollutants). Contact angle (CA) and water droplet penetration time (WDPT) are commonly used methods for assessing biochar hydrophobicity.

HIDROFOBICIDAD EN ANDISOLES BAJO ROBLEDAL (Quercus humboldtii) Y PLANTACIONES FORESTALES (Pinus patula y Cupressus lusitanica) EN LA CUENCA DE LA QUEBRADA PIEDRAS BLANCAS (MEDELLÍN, COLOMBIA) HYDROPHOBICITY OF ANDISOLS OF OAK GROVES (Quercus humboldtii) AND TREE PLANTATIONS (Pinus patula and Cupressus lusitanica) IN THE PIEDRAS BLANCAS WATERSHED ( MEDELLÍN, COLOMBIA )

Revista Facultad Nacional de Agronomía Medellín, 2004
En la cuenca de la quebrada Piedras Blancas se evaluó la persistencia de la repelencia al agua en el horizonte A de Andisoles bajo tres coberturas vegetales: Pinus patula, Cupressus lusitanica y Quercus humboldtii y en tres posiciones topográficas ...

HUMEDAD CRÍTICA Y REPELENCIA AL AGUA EN ANDISOLES COLOMBIANOS BAJO COBERTURA DE Pinus patula Schltdl y Cham CRITICAL MOISTURE AND WATER REPELLENCY OF COLOMBIAN ANDISOLS COVERED WITH Pinus patula Schltdl and Cham

Revista Facultad Nacional de Agronomía Medellín, 2005
En un lote con Andisoles bajo cobertura de Pinus patula Schltdl y Cham se ubicaron 4 transectos sobre los cuales se hizo un muestreo horizontal cada 5 cm, en 4 profundidades, con el fin de establecer si había una zona de transición de humedad crítica en ...
