a synergistic mix of organic acids and compounds for plants and soil.
Persist™ PAF is a unique blend of organic acids (OA) and natural compounds. Academic research and trial data confirm the critical role of OA in creating more vigorous plants and more productive soils.


Explore the Science
Stress Defense

The organic acids and phenols in PAF have been found to help regulate crucial physiological functions in plants to provide resistance against biotic and abiotic stresses, including drought, heat, pathogens, salinity, insect pressure, UV radiation, and heavy metal contamination.
Soil Microbiology

Persist™ PAF contains readily degradable organic acids and compounds that microbes use for metabolism, enhancing both the diversity and population of beneficial microorganisms in the soil. A robust microbiome is crucial to rich, fertile, and productive soils.
Nutrient Availability

Organic acids in PAF, such as malic and acetic acid, have been shown to solubilize and mobilize minerals such as Fe, P, K, and Mg. These organic acids form complexes with soil minerals to release previously unavailable nutrients for plant growth and development.
Plant Development

Karrikins — molecules derived from plant material smoke — have recently been identified as important plant growth regulators. Plants have evolved to respond quickly to these “smoke compounds,” which are found in Persist’s new PAF-based “Karrikaid” liquid nutrient.



14% Yield Improvement
Strawberry Production Trial (Fall 2022)
Compared to the grower’s standard regimen, the yield of marketable strawberries per acre improved by 14.25%* when adding Persist™ Biochar and Persist™ PAF liquid plant enhancer.
Before planting, biochar was placed in the slot at a rate of 480 lbs/acre. 1% diluted PAF was foliar applied at a total rate of 3.5 gal/acre (four applications total). The trial was conducted by Holden Research and Consulting (Camarillo, California).
* Extrapolated flats per acre compared to the grower’s standard.


PAF Provides Greater Root Growth and Total Plant Weight
Celery Nursery Trial (Winter 2023)
Two foliar applications of Persist™ PAF were applied during the outdoor nursery trial. PAF positively impacted plant development, including a 72% improvement in bottom root growth and a 31% improvement in total plant weight. The trial was conducted by Holden Research and Consulting (Camarillo, California).

Application Rates
Use | Dilution Rate in Water* | Benefit |
---|---|---|
Naturally Enhance Soil Microbiology (Apply to soil prior to planting/seeding) | 1:500 (0.2%) – About 1/2 tablespoon (0.25 fl oz) per gallon. | A large and diverse microbiome improves nutrient retention and plant defenses. |
Indoor House Plants (small) | 1:500 (0.2%) – About 1/2 tablespoon (0.25 fl oz) per gallon. | Grow strong and vigorous indoor plants while using less plant food. |
Flowers, Herbs, and Ornamental Plants | 1:500 (0.2%) – About 1/2 tablespoon (0.25 fl oz) per gallon. | Develop more vibrant and productive flowering while using less plant food. |
New Seedlings and Early Growth Stage | 1:350 (0.286%) – About 2 teaspoons (0.33 fl oz) per gallon. | Supercharge seed germination and early plant development. |
Leafy Green Crops (lettuce, broccoli, etc.) | 1:250 (0.4%) – About 1 tablespoon (0.5 fl oz) per gallon. | Increase crop yields while reducing fertilization costs and runoff. |
Corn, Soybean, Rice, Wheat, Sugar Cane | 1:250 (0.4%) – About 1 tablespoon (0.5 fl oz) per gallon. | Increase crop yields while reducing fertilization costs and runoff. |
Grapevines, Fruit and Nut Trees, Orchards | 1:100 (1.0%) – About 3 tablespoons (1.5 fl oz) per gallon. | Increase crop yields while reducing fertilization costs and runoff. |
Strawberries, Blueberries, and Tomatoes | 1:100 (1.0%) – About 3 tablespoons (1.5 fl oz) per gallon. | Improve yields and develop stronger fruit skins, helping to reduce spoilage. |
Turfgrass (lawns, golf courses, parks, etc.) | 1:250 (0.4%) – About 1 tablespoon (0.5 fl oz) per gallon. | Create vibrant green turfgrass while reducing fertilization costs and runoff. |
* Follow the application methods, rates, and coverage areas as prescribed by your specific nutrient and fertilization regimen. Do not apply PAF more than once every two weeks. As an example, a dilution rate of 1:500 means one-part PAF diluted with at least 500 parts of water.
Home Gardeners:
Get More Out of Your Plant Food
Add one teaspoon of PAF per gallon of diluted plant food for optimum results.
It’s estimated that plants absorb only 30-45% of the nutrients in fertilizer.
The organic acids and compounds in PAF make minerals more “plant available” while promoting the growth of nutrient-binding microbes in soil.
