PUMICE IS WIDELY USED to improve the growability of soils—combating compaction and runoff, improving friability and aeration, and holding moisture and nutrients in the root zone. The porous, foamy nature of pumice also makes for an ideal environment for beneficial microbes to thrive.
SoilRox™ works within the soil on two levels. The first is as a structural conditioner, physically amending poor soils—like heavy clay—to be less dense by holding the soil particles apart, creating elemental tilth and friability. This improvement in the distribution of the micro and macro spaces in the soil enhances root zone breathability and drainage.
The second benefit comes from the foamy, sponge-like nature of the pumice stones themselves: the stones—including the tiny fines—are riven with nooks and crannies and pockets that hold moisture and nutrients in the root zone and available to the root systems over a longer period of time.
Though lightweight, SoilRox is somewhat heavier than expanded perlite and vermiculite, and so does not tend to work its way to the surface over time and float or blow away. The irregular, grippy edges of the pumice stone also work to bind it into the soil matrix.
SoilRox™ is Enduring
Organic composts are wonderful and a great addition to any soil improvement effort, but any structural improvements from the compost breaks down over time as the compost is consumed. Without a steady schedule of compost re-application and blending/tilling, the soil tightens and returns to its poor native state. SoilRox is inorganic and will not break down. It remains indefinitely in the soil, providing vital structural support. In applications that are not replanted on a annual basis—like a lawn or any other living ground cover—that’s an extremely valuable benefit.
SoilRox is easily blended with composts to provide the ideal long-term solution to fix-it and forget-it applications like lawns, parks, runoff control constructs, and reclamation projects. The compost provides the kick-start nutrient base to poor or damaged soils, with the pumice remains long after the compost is consumed to provide the elemental tilth that in necessary for the on-going vitality of the newly-established vegatative cover.
HORTICULTURAL PUMICE PURITY DISCLAIMER—Our horticultural mine grades are typically comprised of 98% pumice and 2% other igneous minerals, which are not removed through our mining processes.

SOIL AMENDING RECIPES
Determining soil type using the jar composition test (or similar), provides a reference point from which to correct the performance of a out-of-balance (non-loamy) soil type.
AMENDING CLAY SOIL: Spread 4 inches of SoilRox™ Amender XF and 2 to 3 inches of good compost. Blend into 6 to 8 inches deep into the clay soil.
AMENDING SILTY SOIL: Lay down 2 inches of SoilRox™ Amender XF and 2 to 3 inches of good compost. Blend into 6 to 8 inches deep in the silty soil.
AMENDING SANDY SOIL: Spread 1 inch of SoilRox™ Amender XF and 2 to 3 inches of good compost. Blend into 6 to 8 inches deep into the sandy soil.
NOTE: These recipes are, of necessity, generalized. More thorough soil-typing followed by examination and testing of the amended soil profile would be necessary to determine the quantity (and grade/type) of added SoilRox to attain ideal conditioning.
PLEASE READ THE SHIPPING NOTES BELOW BEFORE PLACING AN ORDER.
1 | For weight-quantities over 20 lbs, shipping cost savings are typically realized by ordering a full-sized production bag (boxed) instead of multiple 20 lb. boxes.
2 | For large orders (over 3 full-sized production bags), please contact us at firstname.lastname@example.org for a freight rate.
3 | The shopping cart system occasionally glitches on an address and throws up an “order can’t be shipped to your address/location” (or similar) error message. Not true. We ship almost anywhere. Contact us at email@example.com and we’ll take care of you.

|SOILROX™ (AMENDER • XF)|
|SoilRox Amender XF opens up pore spaces to greatly improve drainage and aeration (gas exchange) in the root zone, with the extensive fines providing widely-dispersed soil conditioning—capturing, holding and time-releasing moisture and nutrients back to the roots. This elemental restructuring of the soil profile is permanent—SoilRox is inorganic and will not readily break down. This is especially welcome in long-term landscaped areas like lawns and ground-cover features. SoilRox is used to amend expansive areas containing poor native soils. Properly portioned and blended, this SoilRox amender grade reduces or eliminates the need for tilling, as the pumice provides elemental tilth, friability, drainage, and compaction resistance.
Typical Homeowner Applications: Turf lawns, landscaped ground covers, (including ornamental grasses and shrubbery) large garden plots, berry plots, in-ground green house beds (especially for root crops), perennial flower and/or herb gardens.
Typical Commercial Applications: Turf for parks and athletic fields, high-value crop fields, mining and construction restoration/reclamation projects, wetland builds, biofiltration systems, ecology embankments and other runoff control and filtration constructs.
» Size: SoilRox Amender XF consists of a top size of 1/8-inch stones, with extensive fines

|SOILROX™ (BLENDER • SF)|
|The pumice fines in Blender SF, though not as numerous as in the Amender XF, function to further enhance moisture and nutrient retention on a micro level at a more complete in-soil dispersion rate while the larger stones enhance the aeration profile and faciliate drainage—especially important when growing in containers.
Typical Applications: General purpose soil conditioning for potted plants, hanging flower baskets, grow boxes, greenhouse beds, flower beds, and garden plots. Used in lightweight soil and soilless blends engineered for roof gardens and container plantings where soil weight/load is an issue. Also used in container soil blends where a more thorough size-range dispersion of pumice is desired. For landscaping/greenscaping applications, is used to amend native soils with some clay and silt content.

|SOILROX™ (ENHANCER • NF)|
|SoilRox Enhancer NF enhances aeration as well as water and nutrient retention properties. Used in specially-crafted soil and grow media blends where elemental tilth and friability is inherent, making the for need for pumice fines to improve the soil structure unnecessary. Though lightweight, SoilRox is somewhat heavier than perlite and vermiculite, providing more substance and anchoring weight for growing top-heavy plants in pots.
Typical Applications: Blended in specialized soil (no native soil) formulations used for container-grown plants, grow boxes, greenhouse beds, seed pots, and garden plots.
Typical Applications 2: Used in specialized soilless media blends (or used straight up) to grow succulents, bromeliads, cacti. Also used by bonsai growers.
» Size: SoilRox Enhancer NF consists of 3/8-inch to 1/8-inch stones and no fines.
