Terrain Aeration celebrates 50 years
Terrain Aeration’s Terralift system celebrates 50 years of successful deep aeration treatment of bowling greens, sports turf, golf clubs, parks, trees and more.
At the end of September, when bowling clubs are thinking about carrying out end of season maintenance, aeration is a concept that is thought about but rarely addressed. Scarifying, re-seeding, and top dressing are on the front line of the main budget planning. Forgotten are the days when games had to stop play because the ground was waterlogged. A nuisance at the time, but now is the time to bring this problem up at a committee meeting and address it.
The Terrain Aeration Scamper Terralift machine was designed 20 years ago to be able to access most bowling greens. The Scamper Terralift machine hammers a hollow probe (1 1/2" ( 37mm width) one metre into the soil before releasing a controlled blast of compressed air, to a maximum of 20Bar/280 psi. This pressure is monitored or changed by the operator, so there is a slight movement of the top surface before the turf settles back down. Then, the operator knows that he has aerated the ground from one metre to the top surface. On the tail end of the release of compressed air, dried seaweed is incorporated which sticks to the walls of the fractures and fissures created by the main air blast.
Over a period, the seaweed expands and contracts with the moisture content of the soil, swelling and contracting - similar to breathing underground, helping to keep the fissures open longer. The machine uses 2m centre spacings on a staggered grid pattern, each shot interconnecting with the previous ones, ensuring the whole area is aerated and decompacted. The probe holes are backfilled with an aggregate, with the top 1"-2" backfilled with normal top dressing material. Once this deep aeration treatment has taken place, it would not be required for at least another 10-12 years, so it is extremely cost-effective. Deep aeration treatment of a green takes around 5 to 6 hours. The engine/compressor unit is kept off the green with an umbilical air hose to supply the compressed air, thus reducing weight on the green as well as having to start and stop the machine every two metres.
It is preferable that the greenkeeper slits or hollow tines before the Terrain Aeration treatment, to relieve the surface tension so the air can gently blow through those top holes. The treatment can take place before top dressing and re-seed. but if ground conditions at that time deem the green too wet, then the end of season maintenance can continue and later, the Scamper Terralift can come in and aerate the green. There is enough time to fit this in before March of the following year. Terrain Aeration has at times even treated a bowling green mid-season - one had a black squidge where the bowler's back foot was placed. If the treatment hadn't taken place, that green would have played itself out until the end of the season. It would not have been repaired/replaced. That green survived and is going strong many years later. One club commented that after Terrain aerated their green on one of their matches, rain stopped play. They found that they could only have one pint from the bar before the green had drained away of water and play could continue.
A final point. Clubs considering laying in drains will have disruption to their green, but still have compaction panning in between the drain runs. With a track record of treating greens for over thirty years, it's certainly worth Terrain Aeration taking a look before committing to the expense of laying drains.
Terrain Aeration works nationwide, providing deep aeration relief for waterlogging and flooding for bowling greens, sports grounds, amenity areas, golf courses, public spaces and house builders.
