He says it’s not an issue in the valley currently as courses do not use agricultural recycled water. They use water from the aquifer or course stored water. Not an issue.
Seashore paspalum can provide high-quality turf in reduced-light and waterlogged conditions, as well as in soils with wide pH levels. It also requires a lesser amount of nitrogen fertilizer to keep it healthy. But one of paspalum’s most powerful attributes is its ability to tolerate elevated salinity levels that would affect other turfgrass types much more negatively.[/color][/size]“It’s slowly but surely taking over the bermudagrass market for golf courses,” says Jarrett Eledge, golf course superintendent at King’s Crossing Golf & Country Club in Corpus Christi, Texas. “Its drought tolerance is amazing, and the color is stunning.”[/size][/font][/color]
I just finished Cadillac Desert: The American West and Its Disappearing Water. Besides being fairly bewildered by the complexity of water delivery in the American West, I was pretty surprised by the high and persistent salinity levels that come from long periods of irrigation. My question here is whether irrigation salinity is relevant to superintendents or even designers. I guess I'm just curious because it seems like farmland that's perpetually irrigated can have serious salinity problems, and I just wonder if it's an ongoing concern for long-lived courses in areas like the San Joaquin or Coachella Valleys. If so, what are the mitigation efforts? If not, why isn't it a concern. I'm really curious to understand how it relates to golf.
Thanks for this thorough responses everyone, it's really interesting to see how related it all is. Yea, I was fascinated (and a bit horrified) by the book, and the two chapter update from 2018 was pretty wild. It really put the recent Oroville Dam crisis into much better perspective, and I have a lot of respect for the folks out there trying to manage the water for the tens of millions of folks who have decided to live in the desert. I remain deeply concerned about the extent of groundwater pumping though.
Ian, when you say Saskatoon's soil is saline, do you mean alkaline?
