Stall DRY® can reduce your bedding costs and reduce the labor required to clean out your stalls.Ammonia From Urine and Manure is a Health Risk to Animals! Safe, non-toxic Stall DRY® has been providing the best in equine bedding management for over twenty-five years. Chemical free Stall DRY® helps keep stalls and pens fresh and extends the life of bedding. Stall DRY® works in two different ways, making it a highly effective management tool. Stall DRY’s high absorbency works quickly on moisture and wetness. In addition, Stall DRY’s slightly acidic pH helps to neutralize ammonia. Less airborne ammonia means a healthier, fresher barn environment. Experts agree that ammonia exposure is detrimental to a horse’s respiratory function and overall performance. Minimizing ammonia helps safeguard the health of your horse. Ammonia levels are significantly higher near the source – the urine and feces that accumulate on the stall floor. Ammonia is the most heavily concentrated in the bottom 24” of the stall. Horses lying down, or foraging dropped food bits off the floor, are exposed to higher ammonia levels. Not only can ammonia cause direct damage to the respiratory system, compromised airways are more vulnerable to bacterial and viral infections.What Is The STALL DRY® Advantage?• Omri® Listed for use in organic production

What makes Stall DRY a smarter stall-management tool?
Stall DRY® is a safe, natural ammonia-control and deodorizing granule engineered to keep barns, stalls, and trailers fresher and drier. Rather than masking odor with fragrance, it goes after the source by absorbing moisture and neutralizing the ammonia that builds up in soiled bedding. The result is a healthier breathing zone for both horses and the people who care for them, plus measurably longer-lasting bedding.

Who makes Stall DRY?
Stall DRY® is produced by Progressive Planet, the Kamloops, British Columbia company formerly known as Absorbent Products Ltd., with more than 30 years in the natural mineral products industry. Progressive Planet (Tsxv: Plan; Otcqb: Ashxf) operates under the tagline "Products for a Healthy Planet™" and manufactures a family of mineral-based animal-health and absorbent products.

What is Stall DRY made of?
Stall DRY® is a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay, with no harmful additives, making it safe to use around large and small animals alike. Both minerals are prized for their high porosity and natural absorbency, which is what lets the granules pull moisture out of bedding and the stall floor. Because the formula is all-natural mineral, it is Omri Listed, with both US and Canadian Omri certificates available from the manufacturer.

How does Stall DRY neutralize ammonia and moisture?
The granules absorb up to 125% of their own weight in liquid, drawing dampness away from bedding and footing where bacteria and odor thrive. Stall DRY's naturally low pH attracts and neutralizes airborne ammonia molecules at their source rather than simply covering the smell. By keeping wet spots dry and ammonia in check, it also helps reduce flies and creates a cleaner, lower-irritant environment for a horse's lungs and hooves.
Who is Stall DRY for?
Stall DRY® is trusted across stables, animal shelters, zoos, veterinary clinics, pet stores, and racetracks, and works equally well in small-animal enclosures. Horse owners sprinkle it on stripped stall floors and wet spots before re-bedding; it is also used for poultry coops, rabbit hutches, and other livestock and small-pet spaces. Beyond odor control, it extends the life of bedding so you replace shavings or straw less often, and the spent material can be added to compost for sustainable waste management.
How do you buy Stall DRY?
Stall DRY® is sold in two convenient sizes: a 25 lb bag (item W134) and a 40 lb bag (item W135). It is stocked by feed and farm-supply retailers and major marketplaces, and Progressive Planet's website lists where to buy along with downloadable SDS sheets and Omri certificates for documentation. For dealer or volume inquiries, contact Progressive Planet directly.
Stall DRY® by Progressive Planet Products is an absorbent deodorizer for horse stalls, barns, and trailers. It is made from a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay, which together neutralize ammonia and absorb odors and moisture. It is non-toxic, non-corrosive, low dust, and chemical-free, so it can be used on any surface.
How does Stall DRY® control ammonia in a horse stall?
Stall DRY® works in two ways. Its high absorbency quickly soaks up moisture and wetness, and its slightly acidic pH helps neutralize ammonia and inhibit the bacterial growth that causes ammonia to form. Its microscopic porous structure also helps lock in ammonia-causing compounds, so there is less airborne ammonia and a fresher barn environment.
Why does ammonia in stalls matter for my horse's health?
Experts agree that ammonia exposure is detrimental to a horse's respiratory function and overall performance. Ammonia is most concentrated in the bottom 24 inches of the stall, so horses lying down or foraging dropped food off the floor are exposed to higher levels. Beyond direct respiratory damage, compromised airways become more vulnerable to bacterial and viral infections, so minimizing ammonia helps safeguard your horse.
How much Stall DRY® do I use and how do I apply it?
Apply approximately 4 to 5 lbs of Stall DRY® over a 10' x 10' stall, then place your usual bedding on top. For daily maintenance, apply 1/2 to 1 lb over the wet bedding only, pick out the manure, and toss the bedding with your muck fork where you applied it. Used daily, it can also help reduce your bedding costs and the labor needed to clean stalls.
Is Stall DRY® safe and approved for organic use?
Yes. Stall DRY® is OMRI® listed for use in organic production and is safe, non-toxic, non-corrosive, low dust, and chemical-free. Clinical testing has shown it immediately reduces ammonia levels, and it absorbs up to 125% of its own weight in liquid. It has been providing equine bedding management for over twenty-five years.
Can Stall DRY® help with manure composting and fly control?
Yes. Sprinkling 1 to 2 lbs of Stall DRY® over the manure pile every 2 to 3 days controls odors, speeds up composting, and binds nutrients so the manure can be used safely in fields or gardens. Lowering moisture levels in stalls and stables also discourages fly production, helping keep your barn cleaner.
Where besides horse stalls can I use Stall DRY®?
Stall DRY® is ideal for stalls, barns, trailers, kennels, paddocks, pens, and more. It can be used as non-clumping cat litter or to refresh pet bedding, and as an all-purpose absorbent it cleans up oil, fuel, paint, coolant, grease, and other spills. Cover a spill with a generous amount of Stall DRY® and sweep it up once dry.

What is Stall DRY?
Stall DRY® is a safe, natural absorbent and deodorizer made by Progressive Planet for ammonia control and moisture management in barns, horse stalls, trailers, pens, and small-animal spaces. It is a stall-management tool made from a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay. Rather than masking odor, it absorbs liquid and neutralizes the ammonia that causes barn smell.
What is Stall DRY made of?
Stall DRY® is a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay, with no harmful additives. Both are natural minerals known for high porosity and absorbency. Because it contains no synthetic chemicals or added fragrance, it is safe to use around large and small animals alike.
How much liquid does Stall DRY absorb?
Stall DRY® absorbs up to 125% of its own weight in liquid. This high absorption capacity lets it pull dampness out of bedding and the stall floor, drying out the wet spots where bacteria, odor, and flies tend to develop. Keeping the stall drier is the foundation of its odor and ammonia control.
How does Stall DRY control ammonia odor?
Stall DRY® has a naturally low pH, which allows it to attract and neutralize ammonia molecules at their source instead of just covering the smell with fragrance. Ammonia is alkaline, so the low-pH granules chemically counteract it. By absorbing the urine and moisture that generate ammonia and then neutralizing the gas, it reduces the harmful effects of ammonia in the breathing zone.
Who makes Stall DRY?
Stall DRY® is made by Progressive Planet, a natural mineral products manufacturer based in Kamloops, British Columbia, Canada. The company was formerly known as Absorbent Products Ltd. and has over 30 years of experience in the industry. Progressive Planet trades publicly (TSXV: PLAN; OTCQB: ASHXF) under the tagline 'Products for a Healthy Planet™.'
Is Stall DRY safe for horses and other animals?
Yes. Stall DRY® is made from premium food-grade diatomaceous earth and montmorillonite clay with no harmful additives, making it safe to use around large and small animals. It is used in stalls for horses as well as in spaces for poultry, rabbits, and other small pets and livestock. As with any fine mineral powder, applying it to the floor before re-bedding helps minimize airborne dust.
What sizes does Stall DRY come in?
Stall DRY® is available in two sizes: a 25 lb bag (manufacturer item W134) and a 40 lb bag (manufacturer item W135). The size you choose typically depends on how many stalls you maintain and how frequently you re-apply. Both contain the same natural diatomaceous earth and montmorillonite clay formula.
Is Stall DRY organic or OMRI listed?
Stall DRY® is an all-natural mineral product and is OMRI Listed. Progressive Planet provides both US and Canadian OMRI certificates for the product, which can be downloaded from the product page. OMRI listing indicates the product has been reviewed as suitable for use in certified organic operations.
How do you use Stall DRY in a horse stall?
After cleaning and stripping the stall, sprinkle Stall DRY® on the bare floor and on any wet or urine-soaked spots, then re-bed over it with your normal shavings or straw. The granules absorb residual moisture and neutralize ammonia beneath the bedding. Reapply during routine stall cleaning as needed to keep the floor dry and odor under control.
Does Stall DRY reduce flies?
Yes. Stall DRY® helps reduce flies as one of its listed benefits. Because flies breed in damp, ammonia-rich manure and bedding, keeping the stall dry and neutralizing ammonia removes much of the environment they rely on. Drier bedding is naturally less attractive to flies and other barn pests.
Can Stall DRY save money on bedding?
Yes. By keeping stalls drier for longer, Stall DRY® extends the usable life of bedding so shavings or straw need to be replaced less frequently, which reduces bedding costs over time. The upfront cost of the absorbent is offset by buying and hauling less bedding. Many barn operators use it specifically as a cost-saving stall-management tool.
Can spent Stall DRY be composted?
Yes. Stall DRY® aids in composting and can be added to a compost pile along with soiled bedding for sustainable waste management. Because it is a natural mineral blend with no harmful additives, it breaks down within the manure-and-bedding compost stream. This makes it a more environmentally responsible choice for disposal.
Where can I buy Stall DRY?
Stall DRY® is sold through feed stores, farm and ranch supply retailers, and major online marketplaces, and Progressive Planet's website lists where to buy. The 25 lb (W134) and 40 lb (W135) bags are both widely stocked. For dealer accounts or larger volume orders, you can contact Progressive Planet directly at 1-800-910-3072.
Why is ammonia in a barn a health concern?
Ammonia gas builds up as urine breaks down in bedding, and prolonged exposure can irritate a horse's eyes and respiratory system, contributing to coughing and airway inflammation. It is also unpleasant and harmful for the people working in the barn. Stall DRY® addresses these health risks by absorbing the moisture that produces ammonia and neutralizing the gas at its source.
How is Stall DRY different from regular stall fresheners?
Many stall fresheners rely on added fragrance to mask odor, while Stall DRY® works on the actual cause: it absorbs the liquid and chemically neutralizes ammonia using its low pH and natural mineral structure. It is also a single-ingredient-class natural product, food-grade diatomaceous earth and montmorillonite clay, rather than a perfumed chemical blend. That makes it both more effective at the source and safer around animals.
What other products does Progressive Planet make?
Alongside Stall DRY®, Progressive Planet manufactures a range of natural mineral products including Activated Barn Fresh, Red Lake Earth animal feed additive, WunderCat cat litter, Last Crawl pest control, and the Can Dry industrial absorbent line. The company also develops PozGlass™ 100G, a low-carbon, glass-based cement replacement. All of these reflect its mission of turning natural minerals into sustainable solutions.
Is documentation like an SDS available for Stall DRY?
Yes. Progressive Planet provides a Safety Data Sheet (SDS) for Stall DRY®, along with both US and Canadian OMRI certificates, available for download from the official product page. These documents are useful for barns, stables, and commercial facilities that need product safety and compliance records on file. You can also request documentation by calling 1-800-910-3072.
