Profile is an engineered porous ceramic soil amendment made from minerals primarily composed of silica and illite clay. Kiln firing creates a stable, dust-free material with uniform particle size and high cation exchange capacity. Comparative testing versus zeolite, diatomaceous earth, and kiln fired shales or granite shows that Profile combines high porosity, high CEC and high stability. USGA® physical analyses indicate that Profile can increase both drainage and water holding in sand mixes, while meeting USGA® particle size distribution recommendations for a greensmix.
Key Points
- Engineered from minerals primarily silica and illite clay, kiln fired into a porous ceramic with excellent stability, uniform particle size, dust-free performance and high CEC, unlike non kiln fired zeolite and some diatomaceous earth products that can be dusty and brittle.
- Product stability testing (BME Geotechnical Labs) reported ASTM C88 stability degradation of 2.8% and static degradation of 3.5% for Profile over a simulated 20 year time span, with higher degradation percentages for zeolite and DE; USGA requires stability of at least 12.5%.
- USGA® physical analysis of 90/10 and 80/20 sand/amendment mixes showed that only Profile increased drainage and water holding at the same time, consistent with Ohio State research.
- USGA® particle size distribution testing for a greensmix found that Profile met recommendations, while cation exchange analysis reported CEC 14.5 for Profile compared with 2.55 for fired DE and 1.65 for shale/granite.
