Abstract/Contents:Presents a study that "evaluated the effects of 10 intensive type green roof substrates and 2 different drainage systems on green roof weight, turf growth, water consumption, and NO3-, Br-, and metalaxyl-m leaching." Explains that "green roof systems have been proved to be beneficial to the urban environment in several ways." Details methods and materials used in the study, stating that "several studies were performed from July 2004 to December 2006 in outdoor lysimeters having an internal diameter of 30 cm [centimeters]. The lysimeters had a height of 45 cm and they were filled with 2 different drainage systems and 10 different substrates...The lysimeters were seeded with Festuca arundinacea Scherb." Reports that "it was found that evapotranspiration was not significantly different between the substrates in both studies. In contrast, it was found that geotextile drainage system on average had 7.1% more evapotranspiration compared with the sand system. These differences could be attributed to the moisture content distribution of the substrate profile that was affected by the porosity alteration at the interface between the drainage layer and the rootzone." Concludes that "extreme caution should prevail in suggesting the best system for turfgrass growth in green roofs. The approach should be holistic and take into account all turfgrass growth perameters as well as the fate of the agrochemicals in the environment."
