PHOTO A: The thin and discolored bermudagrass turf outside this golf shop patio is a result of copper toxicity. The copper level in the weak turf tested at 193.2 ppm. The reason for the high levels is a copper gutter and downspout that dumps rainwater off the roof of the golf shop and into the drain you can see in this picture. Since the downspout is over the adjacent concrete and not directly over the drain basin, much of the water coming out of the downspout goes onto the turf. You can also see what appear to be copper deposits on the concrete under the downspout as well. Because this area of the country sees an average of more than 50 inches of rain a year, each rain allows copper to leach from the downspout and into the rainwater, ultimately building up in the soil around the drain to toxic levels, causing the turf decline. The superintendent suspected what was causing the problem and did a soil test to confirm his suspicions.
