For generations, farmers have understood the value of dark, rich soil. But building it can take a lifetime. Siro-60 Plus bridges that gap. It’s concentrated soil health in a bag, delivering the essence of that ancient organic matter—humic and fulvic acids—right into your field, with a built-in boost of potassium to see you through the season.
Think of it as a two-in-one workhorse: a long-term soil builder and a season-long plant stimulant. And with both flake and powder forms, it fits right into your existing routine, whether you’re amending acres or feeding through a drip line.
Humic vs. Fulvic: Your Soil’s Dynamic Duo, Explained Simply
Not all organic matter is created equal. Siro-60 Plus combines the two most active forms:
-
Humic Acid (60%): The Soil Architect.
This is the long-term builder. Once in your soil, it acts like a sponge and a glue. It holds water and nutrients in the root zone, preventing leaching. It also binds soil particles into stable, crumbly aggregates—creating the perfect, aerated home for roots to spread and breathe. It’s the foundation. -
Fulvic Acid (10-15%): The Nutrient Taxi.
This is the mobile, short-term activator. Fulvic acid molecules are tiny and charged. They grab onto nutrients (especially micronutrients like iron and zinc) and carry them directly into the plant root or leaf cell. It makes your existing fertilizer program dramatically more efficient.
Together, they create a powerful cycle: The humic acid builds a better soil “warehouse” to store nutrients and water, and the fulvic acid ensures those goods are efficiently delivered to the plant.
The Added Bonus: 10% Readily Available Potassium
We didn’t stop at acids. By including 10% K₂O (Potassium), Siro-60 Plus delivers an immediate, season-long nutrient pulse. This potassium supports everything from drought tolerance and enzyme function to the final size and sweetness of your fruit. It’s the “Plus” that ensures you see a benefit this year, while the humic substances work for years to come.
Why the High pH is a Feature, Not a Flaw
With a pH of 9-11, Siro-60 Plus is deliberately alkaline. Here’s why that’s smart:
-
Natural pH Buffer: If you’re fighting acidic soils, this product gently helps neutralize that acidity over time, making locked-up phosphorus and other nutrients more available.
-
Improved Solubility: This high pH keeps the complex humic and fulvic molecules in a soluble, active state in your spray tank or fertigation system, so they don’t precipitate out.
Flake or Powder? Choose Your Tool.
-
Go with Powder if your main use is foliar spraying or fertigation. It dissolves almost instantly in water with good agitation, leaving no grit in your tanks or filters.
-
Choose Flakes for broadcast soil application. They’re easier to handle with less dust, and they break down gradually in the soil, providing a slow-release effect.
How to Use It: Versatility is the Point
🧱 To Rebuild Your Soil’s Foundation (Flakes Ideal)
-
At Prep: Apply 5-8 kg per acre and work into the topsoil before planting. This is an investment in your land’s future.
-
As a Top Dress: 3-5 kg per acre around established plants during peak growth to recharge the soil biology.
💦 To Supercharge Your Fertility Program (Powder Ideal)
-
Through the Drip Line: Dissolve 2-4 kg per acre in your irrigation water every 3-4 weeks. It will clean your lines and make every other nutrient you inject more effective.
-
As a Foliar Spray: Mix 1.5-2 grams per liter of water. Spray every 10-14 days during key growth stages (e.g., transplanting, flowering, fruit set). The fulvic acid drives nutrients right into the leaf.
🌿 Even in Hydroponics:
-
Add 0.5-1.0 grams per liter to your nutrient reservoir. It stabilizes the solution and improves micronutrient uptake in soilless systems.
Honest Answers from the Field
“How is this different from the cheap, black ‘humate’ granules I’ve seen?”
Many low-cost products are just lignite coal dust—inert carbon with very low active humic content. Siro-60 Plus is sourced from high-quality leonardite and refined to guarantee minimum 60% active humic acid and 10%+ fulvic acid. You’re paying for concentration and guaranteed biological activity.
“Will it really make my fertilizer more efficient?”
Yes. Think of your standard NPK as the cargo. Humic acid builds better roads (soil) to transport it, and fulvic acid provides the trucks (chelates). Research and farmer experience consistently show 20-40% better nutrient use efficiency, meaning you can often use less fertilizer to get the same—or better—result.
“Is it organic?”
Yes. It is mined from ancient, natural leonardite deposits and is a staple input in organic systems worldwide. It’s approved for organic use by major certifiers (but always double-check with your own).
“Flakes or powder for soil?”
For soil, it’s a matter of convenience. Flakes are less dusty and easier to spread dry. Powder works perfectly fine if you’re dissolving it in water first for a soil drench.
