Abstract/Contents:Presents a study conducted to investigate "the effects of a soil surfactant on the wetting and grass performance of a fairway soil in The Netherlands." Details methods and materials used in the study, stating that "this study was conducted on a fairway of golf club 'De Pan', located near Utrecht in the Netherlands. The golf course is constructed on inland dunes of fine sand. In 2004 as well as in 2005 one half of the fairway was treated 4 times with a soil surfactant, whereas the other half was left untreated. The volumetric soil water contents of the upper 5 cm [centimeters] of the soil were measured with a portable TDR [time domain reflectrometry]-device in transects across the untreated and treated part of the fairway." Reports that "two applications of the surfactant resulted in an observable difference in grass color and grass density. The soil water content in the surface layer was clearly higher and the spatial variability was evidently lower in the surfactant treated part compared to the untreated part on several sampling dates." Concludes that "treatments with surfactants tackled water repellency in the surface layer and in the rootzone, improved the infiltration rate of irrigation water, increased the volumetric soil water content in the rootzone, and resulted in a more homogeneously wetted soil. So, water repellency and the development of dry spots and preferential flow paths can be prevented or cured by applying surfactants regularly. An additional strategy would be to manage irrigation frequency and quantity to prevent the soil profile from dropping below its critical soil water content."
