This photo illustrates two things about salinity problems. First, the salinity stress is most evident in the low areas, because the salts drain with the water. Second—and this one can be counterintuitive at first—the solution to an irrigation water salinity problem is to add even more1 of that “bad” water as irrigation.
I participated in a pitch performance workshop put on by the Football Association of Thailand and the Thai League.
John Ledwidge answers a question during the FA Thailand & Thai League’s Pitch Performance Workshop on August 5.
One of the most interesting articles I read last year was Drought responses of above-ground and below-ground characteristics in warm-season turfgrass by Zhang et al. That article describes the drought response after 3 weeks with irrigation withheld:
I noticed something interesting on the lawn of a resort at Ko Kood earlier this month. Looking down from the “Beware of falling coconuts” signs, I noticed that the southern section of lawn was primarily seashore paspalum, and that section of lawn was infested with a variety of weeds.
There are a variety of grasses used for lawns and sports turf in central Thailand. I gave a presentation last week at the American Society for Horticultural Science annual meeting about the growth of three of those grasses:
Do you remember the amazing story from Thomas Sedlmeier who wrote to me last November? He introduced himself, explained how he had started using MLSN and GP, informed me that the grass conditions were beautiful, and also shared some information about maintenance expenses.
Does adding more potassium improve drought resistance? This article by Rowland et al. takes an in-depth look at that important question.
They looked at bermudagrass (Tifeagle and Tifdwarf), seashore paspalum (SeaDwarf), and zoysia (PristineFlora) grown in a USGA sand rootzone.
