Pro Primer™: Organic Liquid Fulvic Acid for Soil Priming

Contact Us
Soil Priming occurs when the input of new soil carbon stimulates the decomposition of old soil carbon. Across soils, adding more carbon increases priming, and adding nitrogen suppresses it. Priming involves diverse soil carbon substrates, so general mechanisms may not exist.

In situations where a post-harvest soil test indicates low Soil Organic Matter (SOM), Soil Priming can be considered to increase SOM for the following season crop. Pro Primer™ 2-0-0+F is a perfect example of a plant-based fulvic acid with soy protein and freshwater algae, combined with carbohydrates and active carbon amino acids, in a soon to be approved for organic use liquid solution, ideal for soil priming.

Soil priming using Pro Primer™, fulvic acid for plants can support the efficiency of enhancers, activators, and promoters such as electron transport chains that complete processes such as the citric acid cycle.

When considering materials for soil priming, Amino Acids (AA’s) have a close correlation with active transcription of genes (Ruthenburg et al. 2007).

Soil priming is assumed to be a key factor in measuring the capacity of soils to function as sources or sinks of atmospheric CO 2 . Because of this, inputs of new OM to the soil can create an accelerated microbial biomass turnover in the short term “Positive Apparent Priming.”

Biofortification & Soil Priming

Drought Priming

The amount of water for a carrier is as low as 5-7 gallons of water when applying ProPrimer™, organic fulvic acid or when applying Explorer™, drastically cutting water use for applications.

1. Drought priming at earlier stages effectively alleviates drought stress during the later stages of growth (Selote and Khanna-Chopra 2010).
2. Drought primed plants were more tolerant to oxidative stress.
3. Priming has improved plant defenses by activating genes for faster and stronger transcription in response to stress (Conrath et al. 2015).

Cold Priming

1. Studies have demonstrated that cold priming can efficiently improve plant tolerance to low temperature stress (Thomashow 1999; Li et al. 2014).
2. Cold priming could contribute to the stabilization of cell membrane against low temperature stress (Iba 2002).

Waterlogging Priming

1. Primed plants could maintain higher chlorophyll content, greater photosynthesis capacity and enhanced light use efficiency (Li et al. 2011).
2. Enhanced stress tolerance to later waterlogging stress by priming was also reported by Wang et al. (2016).
3. Roots are the first to sense the hypoxia under waterlogging.
4. Waterlogging leads to hypoxia, consequently, promotes early senescence of leaves, death of seminal roots, restriction of adventitious root length, affects carbohydrate metabolism, and overall reduced growth (Tan et al. 2008; Herzog et al. 2016).

Abiotic Priming

1. Abiotic priming could even stimulate cross-tolerance to the later-occurred other abiotic stresses. (Wang et al. 2015).
2. Lower energy dissipation in relation to non-primed plants (Wang et al. 2015).
3. Priming can facilitate the accumulation of soluble sugars and hereby reduce damage later under stress such as cold stress.
4. Active transcription of genes which was supposed to be as one of the potential abiotic stress memory markers induced by priming (Conrath et al. 2015).

Priming is a very promising strategy in modern soil management. Multiple results are noted such as both enzyme activity and protein abundance were highly induced by cold priming. Heat priming could improve of plants. thermo-tolerance to the later recurred heat stress in many species.

Application Rates

Rates: 1 qt. – 2 gal/acre. Rotate Pro Primer™ with Nutri-Plus™ in the tank mix. (Inquire for more detailed rates and usage suggestions)


Application timing is dependent on crop, time of season and desired result.



Color & Form

Dark brown liquid


Compatible with most agriculture liquid fertilizers, however, fulvic acid can really “heat up” herbicide. So, we do not offer a recommendation for in crop application of fulvic acid with herbicides to avoid any phytotoxicity damage. Please seek professional advice prior to tank mixing.


Keep sealed in original container. Store in frost-free, dry conditions out of direct sunlight, above 5°C and below 30°C.
