Stall Dry Absorbent Deodorizer by Progressive Planet

Stall DRY® Absorbent Deodorizer an effective stall management tool made from a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay. It has the ability to neutralize ammonia and absorb odors and moisture. Stall DRY® is a trusted name brand used by all animal lovers. It is safe to use and is Omri® listed to use in organic production. Stall DRY® keeps animals safe from the harmful effects of ammonia and absorbs wetness while inhibiting bacteria and mold growth providing a cleaner, healthier, and fresher environment.

Keep your Pens, Calving and Foaling Stalls Clean, Dry and Ammonia Free with Stall DRY®
 Stall DRY® absorbs up to 125% of its own weight in liquid and its microscopic porous structure helps to lock in ammonia causing compounds. Stall DRY® when used daily can improve the environment your animals live in, by reducing ammonia, odors, and moisture. 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 exactly is Stall DRY® Absorbent & Deodorizer?

Stall DRY® is a dry, granular barn-floor product engineered to pull moisture and ammonia out of stalls, pens, coops and litter trays so the air your animals breathe stays cleaner. It is marketed plainly as “a safe and natural solution for ammonia control and deodorization,” and it works the moment you sprinkle it down — one reviewer noted “Works right away. It does!” Rather than masking odor with fragrance, the granules capture the liquid and neutralize the smell at the source.

The Maker Behind Stall DRY

Stall DRY® is manufactured by Progressive Planet Solutions, a Canadian natural-minerals company headquartered at 724 East Sarcee Street, Kamloops, BC, Canada V2H 1E7. The same company produces a family of diatomaceous-earth and clay products including Can Dry and Red Lake Earth, and it positions Stall DRY as part of a sustainable, mineral-based approach to animal management. You can reach Progressive Planet toll-free at with questions about the product or where to buy it.

The natural minerals inside the bag

Stall DRY® is made from a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay — with no harmful additives, so it is safe to use around large and small animals alike. Diatomaceous earth is a soft, porous fossilized mineral prized for its enormous liquid-holding surface area, while montmorillonite clay adds powerful odor-binding capacity. Together they let Stall DRY absorb up to 125% of its weight in liquid.

How Stall DRY neutralizes ammonia and odor

Wet bedding from urine and manure releases ammonia, a gas that can stress an animal’s respiratory system over time. Stall DRY® tackles the problem by absorbing the moisture that fuels ammonia and binding the odor-causing compounds, leaving the floor drier and the air fresher. Because it keeps bedding dry for longer, it also helps extend bedding life and reduce how often you have to replace shavings or straw.

Which animals and spaces it serves

Stall DRY® is built for far more than horse stalls. Owners use it in stables, shelters, zoos, vet clinics, pet stores, racetracks and small-animal enclosures, and across species from horses and livestock to chickens, rabbits, guinea pigs and hamsters. One chicken keeper lays “a thick layer under the roost bars” and scoops it out daily with a kitty-litter scoop; another uses it “on all our rabbit trays, litter boxes, and in the coops” to cut both odor and bugs.

Bag sizes, certification, and how to buy
Stall DRY® is sold in two retail sizes: the Stall DRY 40 lb (item W135) and the Stall Dry 25 lb (item W134). The product is Omri Listed for organic use in both the United States and Canada, and a Safety Data Sheet (SDS) is published on the Progressive Planet website.

The Solution Section (FAQ)
What is Stall DRY™ and what is it made of?
Stall DRY™ by Progressive Planet Products is an absorbent deodorizer for managing odor and moisture in barns, stalls, and horse trailers. It is made from a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay, which neutralizes ammonia and absorbs odors and moisture. It is OMRI listed for use in organic production.
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. Less airborne ammonia means a healthier, fresher barn environment, which matters because ammonia exposure is detrimental to a horse's respiratory function.
How much liquid can Stall DRY™ absorb?
Stall DRY™ absorbs up to 125% of its own weight in liquid. Its microscopic porous structure helps lock in ammonia-causing compounds while pulling moisture out of bedding, which can reduce bedding costs and the labor required to clean stalls.
How do I apply Stall DRY™ to a stall?
Apply approximately 4-5 lbs of Stall DRY™ over a 10' x 10' stall, then place your usual bedding on top. For daily maintenance, apply ½-1 lb over the wet bedding only, pick out the manure, and toss the bedding with a muck fork where you applied the product. Used daily, it helps reduce ammonia, odors, and moisture.
Is Stall DRY™ safe for horses and other animals?
Yes. Stall DRY™ is non-toxic, non-corrosive, low-dust, and chemical-free, and it can be used on any surface. It is OMRI listed for organic production and has been providing equine bedding management for over twenty-five years, helping keep animals safe from the harmful effects of ammonia while inhibiting bacteria and mold growth.
Can Stall DRY™ help with manure composting?
Yes. Every 2-3 days, sprinkle 1-2 lbs of Stall DRY™ over the manure pile, either in the spreader or on the pile itself. This controls odors, speeds up composting, and binds nutrients in the manure so it can be used safely in fields and gardens.
Where else can I use Stall DRY™ besides horse stalls?
Stall DRY™ is suited for stalls, barns, trailers, kennels, paddocks, and pens, and it also works as non-clumping cat litter and pet bedding. It can even be used as an all-purpose absorbent for oil, fuel, paint, coolant, grease, and water spills — cover the spill generously, then sweep it up once dry.
How can I learn more or order Stall DRY™?

What is Stall DRY made of?
Stall DRY is made from a naturally occurring blend of food-grade diatomaceous earth and montmorillonite clay. These two minerals are chosen for their high liquid-holding and odor-binding capacity. Progressive Planet states the formula contains no harmful additives, making it safe for both animals and the people handling it.
Who manufactures Stall DRY?
Stall DRY is manufactured by Progressive Planet Solutions, a natural-minerals company based at 724 East Sarcee Street, Kamloops, BC, Canada V2H 1E7. The company also makes related diatomaceous-earth and clay products such as Can Dry and Red Lake Earth. You can reach them toll-free at 1.800.910.3072.
How does Stall DRY control ammonia?
Urine and manure in bedding release ammonia, a gas that can irritate and stress an animal's respiratory system. Stall DRY absorbs the moisture that drives ammonia production and neutralizes the odor-causing compounds at the source. The result is a drier floor and noticeably fresher air, rather than odor simply being masked by fragrance.
Is Stall DRY safe for animals?
Yes. Stall DRY is made from food-grade diatomaceous earth and montmorillonite clay with no harmful additives, and Progressive Planet describes it as safe for both large and small animals. It is used around horses, livestock, poultry, rabbits and other small pets, as well as by zoos, vet clinics and pet stores.
Is Stall DRY OMRI Listed for organic use?
Yes. Stall DRY is OMRI Listed for organic use in both the United States and Canada, which means it has been reviewed for use in certified-organic operations. Progressive Planet publishes the current OMRI listing documents on the product page. A Safety Data Sheet (SDS) is also available on the site.
What sizes does Stall DRY come in?
Stall DRY is sold in two retail bag sizes: a 40 lb bag (item W135) and a 25 lb bag (item W134). The larger 40 lb size suits busy barns and multiple stalls, while the 25 lb bag is convenient for smaller setups, coops and litter trays.
Where can I use Stall DRY besides horse stalls?
Stall DRY is widely used beyond horse stalls. Owners apply it in stables, shelters, zoos, vet clinics, pet stores, racetracks and small-animal enclosures. It works for horses and livestock as well as chickens, rabbits, guinea pigs and hamsters, making it a versatile single product across an entire property.
Can Stall DRY be used in chicken coops?
Yes, and many poultry keepers do. One reviewer noted it works great in the coop by absorbing moisture and controlling smell, and that they put a thick layer under the roost bars and clean it daily with a kitty-litter scoop. It helps keep the coop drier and the air fresher between cleanings.
Does Stall DRY work for rabbits and small animals?
Yes. A reviewer described using it on all their rabbit trays, litter boxes and coops, reporting that it helps keep bugs down and controls odor. Because it is food-grade and additive-free, it suits the enclosed spaces of small animals like rabbits, guinea pigs and hamsters.
How does Stall DRY save money on bedding?
By keeping stalls and pens drier for longer, Stall DRY extends the usable life of shavings, straw or other bedding. That means you replace bedding less often, which reduces both bedding costs and the labor of mucking out. It effectively makes each bag of bedding go further.
Does Stall DRY help with flies and pests?
Stall DRY helps reduce fly populations because it dries out the wet, soiled bedding that flies need to breed in. Several users also report that it helps keep bugs down in coops and around rabbit enclosures. By removing the moisture pests rely on, it makes the environment less hospitable to them.
Can Stall DRY be composted?
Yes. Stall DRY aids in composting, so soiled bedding treated with it can be added to a compost pile as part of sustainable waste management. This fits Progressive Planet's broader focus on natural, environmentally minded mineral products.
How quickly does Stall DRY start working?
It works on contact. One customer wrote that, just as the product says, it 'Works right away. It does!' Because the granules immediately begin absorbing liquid and binding odor when sprinkled onto wet spots, you typically notice a drier, fresher stall almost immediately.
What do customers say about Stall DRY?
Reviews are strongly positive. A horse owner said it not only sucks up urine in the stall but takes the odor away; a poultry keeper praised how easy it is to scoop out daily; and another reviewer said they'd give it ten stars if the limit weren't five. The recurring themes are fast moisture absorption and genuine odor elimination across species.
What makes diatomaceous earth and montmorillonite clay effective together?
Diatomaceous earth is a soft, porous fossilized mineral with an enormous internal surface area, which makes it exceptional at soaking up liquid. Montmorillonite clay adds strong odor-binding and absorbency. Combining the two gives Stall DRY both its high liquid capacity, up to 125% of its weight, and its ability to neutralize ammonia and other barn odors.
Where can I buy Stall DRY?
You can learn more and find purchasing options at the official product page, progressiveplanet.com/product/stall-dry/, or by calling Progressive Planet toll-free at 1.800.910.3072. The product is also carried by various livestock, pet and farm-supply retailers in the 40 lb (W135) and 25 lb (W134) sizes.
