For decades, humics and fulvics have been marketed as the go-to “soil builders.” They’ve earned their place, but as agriculture becomes more data driven and sustainability focused, today’s growers need inputs that deliver consistent, measurable, and profitable results rather than variable organic effects.
Soltellus™, a bio-inspired polyaspartate polymer engineered by scientists at Dober, redefines what’s possible in soil and crop nutrition. Designed to meet today’s toughest agronomic challenges, Soltellus™ is a new class of nutrient efficiency technology that delivers stronger chelation, 100% biodegradability, simple integration, and a proven 90% success rate driving average corn yield increases of 7.1 bu/A and a 2–6× return on investment.
1. Modern Polymer Technology vs. Ancient Organic Acids
Humic and fulvic acids come from decomposed organic matter. Their composition varies widely by source and region, leading to unpredictable results.
Soltellus™, by contrast, is a precision-engineered polymer built from naturally occurring amino acid chemistry. Designed at the molecular level for targeted nutrient capture, water retention, and controlled release, every molecule is identical, ensuring consistency from one batch to the next. Think of it as precision nutrition management instead of organic guesswork.
Key Takeaways
-
- Humics & Fulvics = naturally variable and inconsistent composition
- Soltellus™ = consistent molecular structure, predictable performance, and proven results across soil types
2. Smarter Chelation, Healthier Soils, Cleaner Fields & Stronger Yields
Soltellus™ redefines chelation (the process that drives nutrient availability and plant performance). Its bio-engineered polyaspartate structure outperforms humics and fulvics and even rivals synthetic chelators like EDTA. By releasing nutrients bound in the soil and reducing losses from runoff, Soltellus™ ensures more of what you apply stays available to your crops.
With a cation exchange coefficient (CEC) of 100, nutrients are held tightly yet released precisely when plants need them most, reducing nutrient leaching and boosting uptake during critical growth stages. Its CEC gives it superior ability to bind essential cations like calcium, magnesium, iron, boron, and potassium while maintaining their bioavailability.
Field tissue data on corn confirms this: Soltellus™ captured 30% more nitrogen, 18% more phosphorus, and 27% more potassium. Simply put, Soltellus™ delivers smarter nutrient efficiency and higher profitability for the modern grower. The result: healthier soils, cleaner fields, and stronger yields.
Key Takeaways
-
- Reduces fertilizer runoff and leaching
- More uptake during key growth stages
- Higher tissue nutrient concentrations
3. Sustainable by Design: Feeding Plants & Soil Life
Soltellus™ isn’t just a nutrient carrier, it’s a microbial catalyst. While traditional acids linger for years and leave behind residues, Soltellus™ works in harmony with nature by converting its own structure into usable organic nutrients, biodegrading completely within 90 days, leaving nothing but stronger soil behind.
As it breaks down, it releases vital carbon and nitrogen that awakens the soil microbiome and provides an added fertilizer boost, sparking life beneath the surface. The result is soil and plants that breathe, thrive, and regenerate; richer in microbial diversity, stronger in structure, and more resilient with every season.
Key Takeaways
-
- Soltellus™ avoids long-term buildup and contributes to regenerative soil systems
- More active microbes build more robust soil
- Higher nutrient cycling efficiency
- Healthier and bigger root systems
4. Proven Yield & ROI Across Crops
While humic and fulvic acids deliver inconsistent results, Soltellus™ is backed by real, replicated field data across major U.S. crops, proving its performance where it matters most. Across 21 field trials conducted in 2023–2024, Soltellus™ achieved a 90% win over untreated checks, driving an average yield increase of 7.1 bu/A in corn, +810 lb/A marketable potatoes, +10 bu/A soybeans translating to a 2–6× return on investment.
These results come from genuine nutrient efficiency, not just added organic carbon, delivering a clear, measurable advantage that Soltellus™ consistently drives yield and profitability.
Key Takeaways
-
- 7.1 bu/A average in corn (90% win rate)
- +810 lb/A marketable potatoes
- +10 bu/A soybeans
- 2–6x average ROI
5. Compatibility & Ease of Use: Built for Hard Water & High Performance
Growers love flexibility and Soltellus™ delivers. It mixes seamlessly with dry or liquid fertilizers, works in-furrow, through irrigation, side-dress, foliar, or broadcast applications, and disperses instantly in water for uniform coverage. Unlike humics that struggle with solubility and stability, Soltellus™ stays consistent from tank to plant.
Hard water? No problem. The strong chelation from Soltellus™ “softens” hard water by binding calcium and magnesium ions, preventing scale, improving flow, and keeping nutrients dissolved and available. The result: fewer clogged emitters, better uniformity, and more reliable performance across every acre.
Key Takeaways
-
- Flexible application
- Instant solubility
- Superior stability
- Chelates calcium and magnesium to “soften” water and prevent nutrient tie-up
- Reduces scale buildup
- Delivers better nutrient availability, uniformity, and predictability across acres
The Final Takeaway
Humic and fulvic acids are yesterday’s organic matter. Soltellus™ is tomorrow’s regenerative polymer. Humics and fulvics walked so Soltellus™ could run; they opened the door to biological soil health, but Soltellus™ takes it further with real science, measurable ROI, and regenerative chemistry built for the modern grower.
More than a soil amendment, Soltellus™ is the new standard for nutrient efficiency, soil vitality, and sustainable profitability. It’s the modern, optimized evolution of soil health powered by precision biochemistry, proven yield gains, rapid biodegradation, and seamless compatibility across farming systems.
Soltellus™ isn’t just a yield enhancer, it's an environmental ally. By keeping nutrients in the root zone and reducing leaching, it supports cleaner waterways, healthier soils, and better fertilizer efficiency. And because it’s 100% biodegradable, it leaves no residues or microplastics.
The bottom line: Soltellus™ delivers what modern farming demands: healthier soils, higher yields, and a proven 2–6× return on investment.
