Pumice is an effective and economical soil amendment, especially for large-area projects like reclamation, stormwater filtration embankments, sports turf, ag fields—enhancing the long-term ability of poor or damaged soils to support thriving cover vegetation, mitigate runoff, and resist compaction.

Use Pumice to Improve the Performance Texture of Soil

  1. 1. soil to support plant life requires a friable silt loam texture. For example, engineered ecology embankments, biofiltration swales and roadside filtration strips function best with sandy-loam textured soils. The nature of pumice itself—a lightweight, foamed-glass stone riven with tiny vesicles—means it also works to improve water- and nutrient-holding capacity and enhances root-zone respiration by resisting compaction. Economical and effective, the right amount of pumice will condition the soil to fit the need. The performance target of the soil, combined with a simple test to establish soil texture, will deter- mine if or how much pumice is needed to change the texture and enhance soil function. Mitigating compaction and runoff and enhancing the ability of the SANDY LOAM TEXTURES: Best for ecology embankments, filtration strips, biofilter swales and engineered wetlands. CLAY TEXTURES: Adding pumice breaks up the sticky density of clay soils, mitigating compaction and runoff erosion, enhancing root-zone respiration for healthy ground cover, optimizing drain- age and water retention needs. SILT LOAM TEXTURES: Unless more aggressive filtering is needed (ecology embankments), soils in these textural range need no additional conditioning with pumice.
