Abstract/Contents:"Clean water is a national concern, particularly in growing urban areas where large population concentrations may strongly impact water resources. Within the urban areas, nonpoint pollution varies according to the land use. The objective of this study was to quantify the degree of chemical runoff from residential landscapes using Resource Efficient Plants (REPs) as compared to more conventional plant communities. Four management systems were investigated: 1)Xeriscape, consisting of 'Prairie' buffalograss [Buchloa dactyloides (Nutt.) Engelm.], autumn sage [Salvia greggii (A. Gray)] and southern wax myrtle [Myrica cerifera (L.)], with no irrigation, fertilizer or herbicide applied; 2) Low Maintenance, consisting of the same microlandscape plants but with 87 lb N/, 22 lb P/ and 15 g 2,4-D/acre/yr with irrigation at 25% pan; 3) Medium Maintenance, with 'Tifgreen' bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis (Burtt-Davy)], 'Nana' dwarf yaupon holly [Ilex vomitoria (Ait.)] and eastern wax myrtle [Myrica heterophylla (Raf.)], with 261 lb N/, 65 lb P/ and 75 g 2,4-D/acre/yr irrigated at 50% of pan and 4) High Maintenance, with the same plants as Medium, but with 392 lb N/, 97 lb P/ and 151 g 2,4-D/acre/yr with irrigation at 70% of pan. Data was collected from late 1993 through 1996. The amount of runoff from a residential landscape is closely associated with the level of irrigation practiced. Our findings show, the more irrigation practiced, the greater the potential for runoff. Selecting plant materials (REPs) which have a lower inherent water need will impact the amount of water, fertilizer and pesticides used and potentially lost as contaminants. The success of efforts to switch to REPs depends entirely upon consumer acceptance of alternative landscapes. These results suggest that either consumer demand for lush turfgrass needs to be moderated or that grass varieties forming denser, greener stands under reduced irrigation and inputs need to be identified."
