It absorbs moisture and urine, controls odors and helps to reduce the harmful effects of ammonia. As a result of controlling odors and ammonia, you will notice a reduction of flies in stalls and pens.

Made from a natural diatomaceous earth deposit enhanced with montmorillonite clay (also known as calcium bentonite), this product can absorb more than its own weight in liquid. It also has a low pH, allowing it to attract and neutralize ammonia molecules. When sprinkled over bedding, it will absorb moisture from the bedding, keeping it dryer so the bedding can be used longer.

Sprinkle a light coat over the stall floor (wood, concrete, dirt etc). Spread additional Stall DRY on wet spots until the surface is dry. Leave this in place. Finally, place the bedding in the stall.

Daily, as you are cleaning the stall, take out the solids and sprinkle about 16 oz on the wet spots. Allow a short time to dry and put the bedding back in the stall. As a result, the bedding will usually last an extra day or so.

Sprinkle on manure piles regularly to reduce flies.

Yes, it can be used in organic production. It is listed by the Organic Materials Review Institute (OMRI) for use in organic production.
Diatomaceous earth is recognized as a non-chemical fly control material. Stall DRY also binds nitrogen and phosphorus which helps to control odors and reduces runoff which may have a detrimental affect on groundwater.
Stall DRY is an all natural product that contains only diatomaceous earth and calcium montmorillonite clay (also known as calcium bentonite) in a granular form, developed specifically to be highly effective at absorbing odors and moisture.

Likewise, Stall DRY Plus offers all the features and benefits provided by our original Stall DRY Deodorizer. However, in addition to the natural blend of DE and calcium montmorillonite, it also contains an added antimicrobial ingredient that kills bacterial odors, as well as a moisture-activated scenting agent.
