Surfactant longevity and wetting characteristics

California Agriculture, 1969
OBSERVATIONS of water repellency in soils made over the past 10 years throughout the world have indicated that this particular problem is more important than had previously been thought.

Runoff and erosion at the micro-plot and slope scale in a small burnt catchment, central Portugal [PDF]

, 2011
Wildfires can have important impacts on hydrological processes and soil erosion in forest catchments, due to the destruction of vegetation cover and changes to soil properties. However, the processes involved are non-linear and not fully understood. This

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.

Enhancing Soil Physical Quality with Compost Amendments: Effects of Particle Size and Additives

Agronomy
This research investigates the impact of compost particle size, compost additives, and application rate on the physical properties of loamy sand soil, particularly focusing on water retention characteristics. Compost, enriched with additives like zeolite,

Remediation Potential of Humic Acids [PDF]

, 2016
V předložené práci byly testovány modifikované lignitické huminové kyseliny za účelem zjištění jejich schopnosti remediace zemědělské půdy. Před samotnou extrakcí jednotlivých huminových kyselin byl lignit modifikován jednou ze série deseti organických ...

Factors injecting effectiveness of two surfactants on water-repellent soils

California Agriculture, 1970
WATER-REPELLENT soils are characterized by two undesirable physical properties: low water infiltration rate, and high runoff. Such soils have been reported in many parts of the world under various conditions, however, one of California's real practical ...
