The spatial extent of water repellence
was derived from the soils and their properties described in DAFWA's soil-landscape mapping of the southwest of WA.
The severity of water repellence
of the surface sand was assessed in the laboratory on the 10 undisturbed (air-dry) samples collected from the field according to methods outlined in Dekker et al.
However, in conventional cropping systems, water repellence
reduces grain yields by preventing some seeds from imbibing water at germination.

in sandy soils of southwestern Australia.
There are a lot of biocides that can generate repellence
and/or that can work as an insecticide.
The "Nanofics 110" coatings are highly water repellent (water contact angle of 110 degrees according to ASTM D5964) and highly oil repellent (oil repellence
level 6 according to ISO 14419) fluoropolymer type of nanocoatings deposited by low pressure plasma technology.
Nonwoven fabrics provide specific functions such as absorbency, liquid repellence
, resilience, stretch, softness, strength, flame re-tardancy, washability, cushioning, filtering, use as a bacterial barrier and sterility.
The ExoFit NEX[TM] is constructed with REPEL[TM] Technology Webbing, providing extreme durability with up to five times more abrasion resistance and water repellence
than previous generations of harnesses.
Fluorinated polymers have always been attracting significant attentions because of their distinct properties, including high thermal and chemical resistance, superior weatherability, oil and water repellence
, low flammability.
The soil often shows some buildup of salts (especially sodium) in the subsoil, has a potential for structural breakdown, and is subject to water repellence
The severe water repellence
would also be influenced by the sandy soils.
