Espartan 2-3-2
Fulvic General Purpose Fertilizer
Vegetable Origin

Overview

Espartan® is a highly refined, vegetable-origin organic fertilizer made from the fermentation and concentration of selected sugar beet molasses. Unlike typical humic-based products, Espartan is dominated by Fulvic Acids—the smallest, most active fraction of natural organic compounds— combined with a balanced 2-3-2 NPK profile and high organic matter content. :contentReference[oaicite:1]{index=1}

Because Espartan contains 33.5% organic matter and 19% fulvic acids, it behaves as both a nutrient source and a powerful biological activator. It improves soil structure, stimulates root development, enhances nutrient uptake, and supports vigorous vegetative and fruiting growth across nearly all crops. Espartan is widely used in organic farming programs throughout the U.S. (NOP-allowed ingredients, but not OMRI certified).

Guaranteed Analysis (2-3-2)

The formula is inherently a 2.6-3.03-2.7, but rounded to 2-3-2 for compliance in states that do not allow decimal guarantees (e.g., TX).

Why Espartan Is Different

  • Vegetable-origin fertilizer — no animal inputs, no waste by-products.
  • High fulvic acid content for rapid plant uptake and nutrient chelation.
  • Highly filtered to flow cleanly through drip irrigation and hydroponic systems.
  • Excellent “microbial food” — feeds beneficial microbes, fungi, and biofilms.
  • Very cost-effective compared to other organic fertilizers.
  • Commonly approved in organic audits by CCOF and other U.S. certifiers (ingredients allowed under USDA/NOP rules).

Fulvic Acids: What They Do

Fulvic acids are extremely small, highly reactive organic molecules that carry nutrients into plant tissue and stimulate root growth and metabolism. In Espartan, fulvic acids provide:

  • Powerful nutrient chelation – especially micronutrients like Fe, Mn, Zn, Cu.
  • Improved nutrient mobility in soil, hydroponic solutions, and plant tissues.
  • Enhanced enzymatic activity in roots and leaves.
  • Stress reduction under heat, cold, salinity, and drought.
  • Greater microbial respiration and reproduction.

Because fulvics are smaller than humics, they remain soluble at all pH levels and can be used safely in all irrigation systems, including hydroponics and fertigation.

Outstanding Compatibility With Microbial Products

Espartan is one of the best organic fertilizers for pairing with microbial inoculants, compost teas, EM blends, mycorrhizae, and biological stimulants. Its high fulvic and organic matter content acts as a carbon and energy source for microbial communities.

Why growers use Espartan with compost tea:

  • Accelerates microbial reproduction rates.
  • Increases microbial mobility and root colonization.
  • Provides an ideal carbon substrate without introducing contamination.
  • Improves tea stability and efficacy after application.

Safe & Effective in Aquaponics

Espartan is unusually clean for an organic fertilizer — free of heavy humic residues and low in ash — making it one of the few true organic fertilizers that works safely in aquaponic systems.

Benefits in aquaponics:

  • Safe for fish at recommended rates.
  • Does not clog filters or media beds when properly diluted.
  • Provides carbon for nitrifying bacteria (supports the biofilter).
  • Enhances plant nutrient uptake without disrupting water chemistry.

Many aquaponic growers rely on Espartan specifically because it performs well in both the aquatic environment and the plant root zone.

General Plant Benefits

  • Improves soil structure and aeration.
  • Increases rooting system quality and biomass.
  • Improves humidity retention in root zones and media.
  • Enhances nutrient absorption through chelation and fulvic transport.
  • Improves microbial activity and enzymatic processes.
  • Provides an even, gentle organic NPK source that complements any feeding program.

Application Recommendations

IRRIGATION

  • Drip Irrigation: 1–1.5 gallons/acre (every 7–10 days)
  • Surface Irrigation: 1.5–2 gallons/acre (every 7–10 days)

HYDROPONICS

  • 2.5–3.5 pints/acre (every 7–10 days)
  • 1.7-2.5 ml per gallon daily in continuous liquid feed (every 7–10 days)

FOLIAR

  • 10–20 ml per gallon depending on crop and development stage

Crop Notes

  • Cut flowers & ornamentals: Throughout the growing season.
  • Vegetables: Ideal during the first 2/3 of the crop cycle, but usable throughout.
  • Citrus & fruit trees, grapes & olives: Apply during spring and summer growth.

Compatibility Notes

  • Do not mix with sulfur or copper except under supervision.
  • Do not mix with high-alkaline products (mineral oils).
  • Avoid mixing with hydrogen peroxide or chlorides.
  • Flush irrigation lines after application (as with all organic nutrients).
  • Always perform a jar test for new tank mixes.
