“…The result is improved growing environments, more efficient irrigation, reduced environmental risk from preferential flow and water savings of up to 30% or more. This has been extensively studied and documented in turfgrass management (Cisar et al, 2000;Karnok and Tucker 2002;Park et al, 2004;Dekker et al, 2005;Oostindie et al, 2005;Karcher et al, 2006;Aamlid et al, 2009;Hallet, 2007;Leinauer et al, 2007) and is now being explored in agricultural crops as well (Hopkins and Cook, 2007;Speth et al, 2005;Rowland et al, 2007).

Soil water repellency causes at least temporal changes in the hydrological properties of a soil which result in, among other things, suboptimal growing conditions and increased irrigation requirements. Water repellency in soil is more widespread than previously thought and has been identified in many soil types under a wide array of climatic conditions worldwide. Consequences of soil water repellency include loss of wettability, increased runoff and preferential flow, reduced access to water for plants, reduced irrigation efficiency, increased requirement for water and other inputs, and increased potential for non-point source pollution. Research indicates that certain soil surfactants can be used to manage soil water repellency by modifying the flow dynamics of water and restoring soil wettability. This results in improved hydrological behavior of those soils. Consequently, the plant growth environment is also improved and significant water conservation is possible through more efficient functioning of the soil. Vodoodpudivosť pôdy spôsobuje prinajmenšom dočasné zmeny v hydrologických vlastnostiach pôdy, ktoré okrem iného môžu viesť k suboptimálnym podmienkam rastu rastlín a k zvýšenej potrebe závlah. Vodoodpudivosť pôdy je rozšírenejší jav, ako sa pôvodne predpokladalo; bola identifikovaná v mnohých pôdnych typoch a klimatických podmienkach na celom svete. Dôsledkom vodoodpudivosti pôdy je strata zmáčavosti, zvýšený povrchový odtok a preferenčné prúdenie, znížená dostupnosť vody a iných vstupov pre rastliny, znížený účinok závlah, zvýšené požiadavky na vodu a iné vstupy, ako aj zvýšené riziko plošného znečistenia. Výskum naznačuje, že niektoré povrchovo aktívne látky (soil surfactants) môžu upraviť vodoodpudivosť pôdy obnovením omáčania a modifikáciou dynamiky vody. Výsledkom je zlepšenie hydrologických vlastností pôdy. Podobne, výsledkom je zlepšenie prostredia pre rast rastlín, zvýšenie retencie vody v pôde a teda aj efektívnejšia funkcia pôdy.KĽÚČOVÉ SLOVÁ: vodoodpudivosť pôdy, efektívnosť závlahy, povrchovo aktívne látky, preferované prúdenie, retencia pôdy.

“…In severe cases SWR can render soils non-usable for crop production (Hallett et al, 2001). In less severe cases, it can cause reduced plant performance (Cisar et al, 2000;Hopkins and Cook, 2007;Leinauer et al, 2007). Unaddressed, this reduced PAW also reduces irrigation efficiency.…”

“…As many amenity soils, particularly golf greens, are constructed from sandy soils, they are very prone to the development of water repellency (Cisar et al 2000). These soils also provide a better habitat for fungi than bacteria because the small particle surface area and pore size distribution provides poor bacterial habitat (Hallett et al 2001a).…”

This article describes the phenomenon of soil water repellency, starting from the fundamental principals of water transport and storage in soil. Soil water repellency is a reduction in the rate of wetting and retention of water in soil caused by the presence of hydrophobic coatings on soil particles. For crop production and the maintenance of amenity turf, water repellency can stress plants resulting in poorer yield quality or grass 'playability' , respectively. The biological causes of water repellency, primarily the influence of fungi, will be discussed, as an understanding of the source of the problem will be beneficial in developing solutions. Exacerbation of repellency through climate change and the use of 'engineered' soils for amenity surfaces will be demonstrated using research findings from around the globe. In developing solutions to soil water repellency, its positive benefits, if maintained at very low levels, need to be considered. Water repellency is a key process in the physical stabilisation of soil and its impact on evaporation also needs to be considered. Before developing a rapid solution to repellency based only on water transport rates, a holistic understanding of the impacts on soil water relations is essential.

“…An effective method to prevent soil water repellency, which is often used in sport turfs to prevent dry patches, or localised dry spotting, is to irrigate frequently, thus maintaining high soil moisture levels (Cisar et al 2000). Other methods to mitigate this include the use of surfactants as commonly applied to golf greens (Cisar et al 2000, Kostka 2000 and the addition of clay to the top soil (claying) either by deep ploughing into a clayey subsoil, or by a top dressing with clay, as used successfully in some regions in Australia (Carter et al 1998).…”

Effect of kaolinite and Ca-montmorillonite on the alleviation of soil water repellency

The effects of adding 1-3% (weight) kaolinite or Ca-montmorillonite on the we�ability of silica sand, made highly water repellent with stearic acid, was studied during we�ing and prolonged drying phases at 50°C. The persistence of water repellency was estimated with the water drop penetration time (WDPT) test. A�er we�ing water repellency disappeared in all the samples. During the drying phase, water repellency re-appeared in all samples (untreated and clay-treated) as the water content decreased below 1%. Repellency did, however, not reach pre-we�ing levels. The effect of clay additions on water repellency differed strongly between the two clay types. Kaolinite reduced WDPT, while Ca-montmorillonite caused an increase in WDPT in the already highly repellent sand. Potential mechanisms for the alleviation effectiveness of kaolinite are proposed, with key factors being the high adhesion forces between water and clay mineral surfaces, and the ability kaolinite to disperse. In the case of Ca-montmorillonite, its lower affinity for water may lead to a displacement of water molecules at mineral surfaces by amphiphilic organic compounds, which may result in increased repellency. This phenomenon clearly requires further investigation.
