PHOTO quiz answers John Mascaro President of Turf-Tec International PROBLEM A This 18-hole golf course in southwest Florida is wall-to-wall seashore paspalum, selected because of water-quality issues. This particular unused and largely out-of-sight area was soon to be completely renovated to native landscape, as shown in the photo below. After a very wet summer, this area was hit with take-all root rot (Gaeumannomyces graminis var. graminis), but the superintendent was not too concerned because of the pending renovation. When the turf died, he noticed this green strip down the center of the dead area and had to investigate. As it turned out, a few months before this popped up, a member of the crew set his rotary walk mower way too low and scalped a pass. He then set the correct height and fnished mowing. The crew topdressed the scalped pass immediately, and it grew back in a couple of weeks. After that very wet summer, the brown grass you see around it started to decline, but that stripe remained emerald green. That scalping turned out to be great medicine for this grass, as the majority of the thatch and biomass was removed at the time of scalping, and the topdressing prevented the disease from occurring in that mower strip. The superintendent commented that this is living proof that thatch removal and topdressing, through cultural practices (accidental, in this case) really is the best stress and disease prevention.

PROBLEM B The material found on these walls in the pump station is actually salt. Toward the end of the season, the pump started shooting water from one of the bushings, requiring service. The irrigation water for this golf course is pumped from an underground well, and the water is high in pH, bicarbonate/carbonate (HCO3/CO3) ions, sodium (Na) and total dissolved salts (TDS). When the water sprayed from the pump, it wet the walls and penetrated the more porous grout between the cement blocks. When the water evaporated, it left this salt residue on the inside of the pump station. Because the water is high in Na and HCO3/CO3, an acid injection system is currently being installed to remove the excess HCO3. This will not only help with the longevity of the pump station, but will also be a huge beneft for the overall health of the turf.
