Why Water Isn't Enough — Dust Control in Equestrian Arenas

Ask any yard manager about dust and you'll get a knowing look. It's one of those problems that never quite goes away — especially in summer, or during dry spells when the arena surface turns to powder underfoot.

Most yards rely on water. A bowser or sprinkler system, applied before exercise, takes the edge off the dust. But it's a short-term fix. A resting horse inhales around 16 gallons of air per minute — and during vigorous exercise, this can increase to 600 gallons per minute. That means even moderate dust levels during a schooling session represent a significant respiratory load for the horse.

The problem with fine particles

The main cause of dust in equestrian centres is a dry surface. Whilst it may look fine, dust particles become airborne as soon as a horse or rider begins working on the surface or the wind blows across it. Larger particles settle back down — but the finer granular particles stay airborne.

Those fine particles are the dangerous ones. They're small enough to be inhaled deep into the lungs. Research has shown that respirable crystalline silica exposures in equestrian work environments fall within the range associated with increased risk of serious lung conditions — including lung cancer. Horses are particularly susceptible to equine asthma and chronic obstructive pulmonary disease (COPD), which can cause coughing, wheezing, and reduced lung function, directly affecting performance and welfare.

Common solutions and their limitations

Salt draws moisture effectively but eventually washes away, and prolonged use can dry out tack and horses' hooves. Waxed surfaces work well but a quality wax treatment can cost upwards of £5,000 per year. Rubber and wood chippings help weigh down particles but degrade over time.

Water remains the most common approach, but it comes with its own problems. Arenas that are watered frequently to suppress dust can face increased humidity — and in enclosed spaces, that creates conditions where microbes, mould and fungi thrive. Getting the balance right with a bowser is time-consuming, expensive and inconsistent, particularly outdoors where evaporation undoes your work within hours.

A longer-lasting alternative

Dusra is a biodegradable liquid dust suppressant that binds surface particles together and retains moisture more effectively than water alone. Unlike a bowser treatment that evaporates within a few hours, Dusra stays active in the surface for significantly longer — meaning fewer applications, less water consumption, and a more consistent, rideable surface throughout the day.

It's safe for horses, riders, yard staff and the environment — no synthetic chemicals, no harmful residue. And it's straightforward to apply: spray it on like water and let it do the work. Whether you run a competition yard, a livery centre or a riding school, Dusra helps you maintain a consistent, safe surface all year round.
