There is an increasing concern for the potential movement of chemicals from the treated sites following the use of certain management strategies for turfgrass maintenance. In some areas, these concerns are being translated into proposed government regulations for turfgrass management that could reduce amounts of chemicals available for the management strategies. The objective of this study was to develop a lysimeter system with a controlled environment for measuring the potential movement of pesticides through golf course greens designed to simulate United States Golf Association specifications. A track irrigation system was mounted above 36 lysimeters to simulate irrigation and rainfall common to the golf courses in the Piedmont region of Georgia. The system was tested for a 52-wk period using ‘Tifdwarf’ bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy]. An excellent turfgrass sod was maintained during the trial period. The coefficient of variation (CV) in water delivery within the growth boxes was 5.6% and the average Cv of water delivery between the 36 growth boxes was 6.2%. The two rows of lysimeters contained either a 80:20 or 85:15 (sand/sphagnum peat moss) mixture. The average Cv for differences in volume of effluent exiting the lysimeter bases was 22%. Data for determining the potential movement of applied chemicals from golf course greens can be obtained from this system.

This study was funded by U.S. Golf Assoc.
