About Us

• Founded 25 years ago by horse owners John Clark and Teri Coss-Clark, TRC & Associates offers environmentally safe products to provide solutions to equine essentials problems, such as dust and mud. Our horse supplies products include ARENACLEAR to control dust, and PastureDRY to reduce mud. For us, offering a safe way to reduce dangerous dust is personal. After Teri had a serious reaction during a dusty outdoor horse event and woke up in an emergency room diagnosed with asthma and COPD, she wanted to find a way to continue riding. Teri’s passion is to help other horse lovers and their horses through effective arena dust control. She and John did their research, investigating formulas from agricultural supplies and came up with ARENACLEAR. The formula was first invented in California as a conditioner to make soil healthier and purer after it had been depleted. Designed to remove fertilizers and chemicals from the soil, this organic product is safe for animals and people, as well as dogs’ paws, horses’ hooves, saddles, blankets, stalls and anywhere else you use it. Other dust-inhibitors on the market contain magnesium chloride, can be corrosive and are expensive. Not ARENACLEAR, which is the least expensive product of its kind on the market for horse arena dust control. One gallon covers 10,000 square feet at a depth of 3-4 inches of footing. We sell to clients all over the world and are proud of our reputation for time-tested non-toxic products. Teri has published numerous articles in industry publications and given seminars at equine trade shows. An irritant found in dust, crystalline silica, looks like broken glass under a microscope. Once inhaled into the lungs it can cause irritation, and in some cases form nodules. Not only does dust affect you and your horses, but can spread to your neighbors too. Today, there is a slew of acronyms for respiratory issues horses are facing: Inflammatory Airway Disease (IAD), Reactive Airway Disease (RAD) and Exercise Induced Pulmonary Hemmoraging (EIPH). Ideal for indoor or outdoor use, on all types of surfaces including sand, sand/clay, dirt or sand/fiber footings, arenas, paddocks, dirt roads, athletic fields—the product won’t wash away. It saves time as well as money. Our clients report that an application of the product “drastically cut down on the time it took to prep the arena” and that they “have more riders in the arena at one time and ride for longer.” Use of the product can reduce the amount of watering needed by up to 50%. Their other product, PastureDRY, eliminates mud indoors and outdoors by breaking up the soil’s barrier that stops water from penetrating. It’s beneficial to animals who dwell in areas that are muddy, which can cause skin conditions and infections. While the majority of our business lies in equestrian applications, we also sell to dog training facilities, ATV and motocross racetracks and practice facilities. Another one of our products, FAIRWAY-MAGIC, helps golf courses save water and reduce fertilizer by helping water penetrate more efficiently into the soil. Give TRC & Associates a call today.
