University Research

Research results from leading universities around the country confirm the fact that Profile Porous Ceramic outperforms other amendments in a variety of real world applications. From reducing drought stress and bulk density to increasing hydraulic conductivity and improving turf quality, Profile is the solution for your environment.


University of Florida
Profile® Porous Ceramic
Dr. Grady Miller reports, “The statistical trend indicates Profile-amended plots to be the highest
in quality and with the least L.D.S. symptoms.”

Tifton Physical Soil Labs
Profile Porous Ceramic
Powell Gaines reports, “In every sand tested, Profile always increases water retention without 
sacrificing percolation rates.”

University of Missouri
Profile Porous Ceramic
Dr. Dave Minner concludes, “After three years of research, plots topdressed with Profile significantly 
improved turf quality and reduced localized dry spot injury.”

Penn State University
Profile Porous Ceramic
Dr. Charles Mancino says, “Plots topdressed with Profile had higher overall quality than plots topdressed
with sand during drought stress. The 100% Profile topdressed plots exhibited higher quality and lower 
drought stress than wetting agent-treated plots.”


Iowa State University
Profile® Field & Fairway™
Three-Year Study
1- and 2-ton rates per 1,000 square feet of Profile Field & Fairway were tilled into intense traffic sports
fields with native soil. Results of the study showed that the plots revealed significant reductions in 
bulk density with the 1- and 2-ton rates, indicating more favorable bulk density and less compaction.


University of Missouri
Profile Porous Ceramic
It was found that all the greens constructed with Profile (as compared to peat root zone) had significantly
higher water infiltration. After four years of topdressing with Profile, it was found that Profile doesn’t 
produce the negative effects of layering.

University of Florida
Profile Porous Ceramic
It was reported that hydraulic conductivity increased with an addition of Profile.

Pennsylvania State University
Profile Porous Ceramic
A field study conducted showed that no physical obstruction (such as layering) occurred using Profile.


University of Missouri
Profile Porous Ceramic
Greens constructed with sand and Profile versus sand and peat ALWAYS had higher infiltration and 
perc rates. Also, when Profile was used in a 15% to 30% construction mix, root branching and 
root volume increased as the amount of Profile in the mix increased.


North Carolina State University
Profile Porous Ceramic
Profile blended into organic potting mixes, reduced leaching of potassium and made more 
potassium available to the plant.

University of Missouri
Profile Porous Ceramic
The top three inches of soil topdressed with Profile had more potassium than the plots 
topdressed with sand.

Ohio State University
Profile Porous Ceramic
Increased Profile percentages resulted in a uniform increase in CEC for all sand and sand/peat blends. 
Profile has the ability to reduce potassium leaching and make potassium available to the plant.

University of Florida
Profile Porous Ceramic
Adding 10% Profile to the sand increased potassium concentration 256% in tifdwarf bermuda tissues. 
Diatomaceous earth and peat are not adequate in retaining potassium compared to Profile.


The Ohio State University
2010 - Present
Computer modeling studies, completed by Dr. Ed McCoy confirmed that a root zone amended 
with 15% Profile can delay the onset of visual drought stress by up to 3 days relative to 
un-amended sand and by about 2 days compared to a sphagnum peat amended root zone.


The Ohio State University
2011 - Present
A non-equilibrium sorption experiment, completed by Dr. Ed McCoy and Dr. Keith Diedrick, 
cited that no salinity hazard exists using Profile inorganic amendments.
