Persist biochar provides exceptionally high porosity and surface area (BET). The greater the porosity, the more effective biochar is at holding moisture, enhancing microbial activity, filtering pollutants, and binding nutrients.

Not all biochar is the same. Biochar characteristics should be verified with a 3rd party laboratory analysis.
This evaluation compared USGA-specified sand alone to the same sand mixed with 20% Persist® biochar, consistent with USGA recommendations for putting green construction. Compared to USGA sand alone, the Persist® biochar/sand mix (20/80) provided:
- Better aeration (+11% air-filled porosity)
- Improved water retention (+27% water-filled porosity)
- Increased infiltration (+3% infiltration rate)
The Persist® biochar/sand mix (20/80) meets all USGA recommendations evaluated, including gradation and uniformity coefficient.
