Improving Soil Structure

Persist Biochar Reduces Compaction, improves soil porosity and aeration, while retaining More water and nutrients.

Sports Fields

Persist™ biochar helped alleviate compaction issues at a professional baseball park.

Golf Courses

Persist™ biochar reduced soil compaction while improving microbial activity, nutrient efficiency, and water retention at a leading golf course.


In recent trials, soils amended with Persist Biochar showed a 37-51% improved moisture retention compared to control plots.

Biochar Porosity

The complex network of pores, tunnels, and pathways improves aeration and infiltration, microbial activity, and water efficiency.

Various Particle Sizes

Whether you want to apply biochar granularly or in liquid form, Persist provides custom and precise particle size control for ease of application.

Compacted soils restrict root growth, impede water infiltration, diminish nutrient availability, and compromise overall soil structure, adversely affecting plant health.

Persist™ biochar provides exceptionally high porosity and surface area (BET), making it more effective at holding moisture, enhancing microbial activity, filtering pollutants, and binding nutrients. 

Persist Biochar under microscope

Turf and Soil Diagnostics Labs (Linwood, Kansas)

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.

Persist Premium Biochar

One pound of ultra-porous Persist™ biochar has a surface area of over 25 football fields. Water adheres to these surfaces to retain moisture in soil up to six times longer. The microscopic pores also serve as a habitat for microbes, creating a microbe mega-factory in your soil.

Persist PAF Bio-liquid

Persist™ PAF is a unique liquid blend of organic acids, phenols, and natural compounds. While biochar provides shelter for microbes, PAF provides the food. Recent crop trials, including strawberry, pepper, and soybean, show significant improvements in nutrient uptake and yield.

Independently Verified to the Highest Quality Standards

OMRI Listed® for use in certified organic operations under the USDA National Organic Program

Certified by the USDA as an all-natural, 100% biobased product (BioPreferred® program)

Meets the stringent quality standards established by the International Biochar Initiative

Certified carbon negative by Puro.Earth, the world’s leading carbon crediting program
