Topdressing – why , when and how
L ike a lot of turf maintenance activities , topdressing techniques have evolved over the years as thoughts around the benefits of lighter , more frequent dressings have resulted in proven improvements in surface health and playability . Redexim UK explore the ‘ why , when and how ’ of topdressing to ensure optimum results from every operation .
Why ?
The application of sand will bring multiple benefits to a surface . Looking at golf greens in particular , topdressing will modify the soil structure by adding a medium that will improve the porosity - meaning infiltration rates , oxygen movement and nutrient retention within the soil are all increased . A good soil structure is the backbone for many a successful maintenance activity , not least overseeding , where topdressing provides a high-quality medium for new roots to grow . Not only does the dressing introduce new minerals to stimulate growth , the loose particles provide a tilth for the roots and shoots to get a foothold in the early stages of establishment and germination .
It also plays a key role in stabilising a surface , particularly when conducted in conjunction with aeration programmes . Topdressing following tining or hollow coring can help to speed up recovery and provide a level , truer surface for golfers to play on . This ability to smooth a playing surface means it can also be utilised during the recovery and repair of divots , pitch marks or other damage .
Topdressing should also be employed for the control and prevention of the issues associated with excess levels of organic matter . Along with mechanical intervention in the form of scarification and verti-cutting , topdressing can effectively dilute thatch accumulations to improve the growing environment .
