POWERFUL CATALYSTs FOR WATER and nutrient efficiency IN SOIL
Persist™ Premium Biochar holds more water and nutrients in the soil to help naturally rebuild the soil and make it more drought-resistant to allow plants to thrive.
Persist™ PAF is a 100% bio-based liquid that may enhance plant growth by improving plant nutrient uptake and increasing microbial populations in soil.
Persist Third Party Validation
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.

How VGrid is fighting climate change with Persist
Persist™ PAF and Biochar provide a 14% yield increase in marketable strawberries per acre.

Persist treatment produces 7% more soybean plants per acre and 4% larger plants.
The Persist™ Biochar Difference
Purity
Persist biochar is manufactured in a high-temperature gasification process that maximizes the removal of volatile organic compounds (VOCs) from the biomass. This proprietary process also yields a biochar with greater than 90% fixed carbon content, which is significantly higher than most other brands of biochar. Persist has low ash content, consistent particle size distribution, and is made from 100% California-grown waste pistachio shells, which would otherwise go to the landfill.
Porosity
Persist’s proprietary high-temperature production process also creates an extremely porous biochar with an intricate network of microscopic pores, cavities, and channels. The result is a massive “surface area-to-volume” ratio, which maximizes the water holding capacity and nutrient binding capabilities. One ounce of Persist™ in fact has a surface area equal to 1-1/2 football fields. Persist’s surface area of 200-300 m2/g compares to other biochar at <20 m2/g.
Stability
Biochar is an effective method for capturing carbon that would otherwise enter the atmosphere. But how much carbon is captured and for how long is not the same for all biochar. Persist is over 90% fixed carbon, meaning that more carbon is captured per pound compared to others. Additionally, if the oxygen-to-carbon (O:C) ratio of biochar is less than 0.2, then the half-life is greater than 1,000 years. With an O:C ratio of 0.05, Persist provides significantly longer sequestration.
Biochar saves water, reducing the impact of drought.
49 Day Drought Trial with Flowers
A series of studies were conducted to evaluate the water holding capacity of biochar. In one, flowers were planted in two self-watering pots, which were then top-watered and filled.
After 15 days, the water level indicator in the non-biochar planter dropped significantly but remained virtually unchanged in the biochar-amended planter, even after 30 full days of no water.
After 49 days of no additional watering, the flowers in the biochar-amended pot were still in bloom and the leaves were green and healthy. Flowers in the non-biochar pot were dead.
NEW Micronized biochar for fertigation, drip irrigation, and foliar spray systems.
- Carefully screened particles less than 75 microns (0.075 mm) designed for liquid suspension and application.
- Enhances dispersibility of biochar in soil for more precise nutrient delivery while reducing loss from volatilization.
- Micronized particles further improve water retention, nutrient availability, and microbial activity in soils.
