Imagine if you could fix poor soil structure, make your existing fertilizers work harder, and build long-term drought tolerance—all with one product. That’s the promise of a truly premium humic substance, and SIRO-70 is engineered to deliver exactly that.
But here’s the thing: not all “humic acid” is created equal. The magic isn’t just in the amount, but in the balance. With an industry-leading 70% Total Humic Extracts and a remarkably high 35% Fulvic Acid content, SIRO-70 is designed to work both in the soil and inside the plant from the moment you apply it.
The Inside Story: Why the Humic/Fulvic Split Matters
Most humic products are vague about their fulvic content. We lead with ours because it’s what makes SIRO-70 fundamentally different. Think of it as a two-person team:
-
Humic Acid (The Soil Builder): This is the long-term strategist. It’s a large molecule that works in the soil, binding to particles to create better structure (like turning hard clay into crumbly loam), building organic matter, and creating a permanent reservoir for water and nutrients.
-
Fulvic Acid (The Plant Shuttle): This is the active field agent. It’s a very small, low-molecular-weight molecule that can actually enter the plant root and leaf. Once inside, it chelates nutrients, making them more mobile and available, and acts as a powerful biostimulant.
SIRO-70 gives you both in optimal balance. You’re not just amending the soil for next year; you’re actively feeding and stimulating this season’s crop at the same time. The added 10% K₂O provides an immediate, bioavailable potassium boost that works synergistically with this system.
The Alkaline Advantage: More Than Just a Number
A pH of 9-11 might seem extreme, but it’s a deliberate, powerful feature for two key reasons:
-
Acidic Soil Correction: It gently and naturally raises the pH of acidic soils, unlocking nutrients like phosphorus and calcium that were previously “locked up” and unavailable to plants.
-
Enhanced Stability & Compatibility: The alkaline nature increases the product’s solubility and shelf stability. In practical terms, it dissolves quickly and completely in your spray tank or irrigation system without clogging.
How to Use It: Match the Method to Your Goal
🧱 For Long-Term Soil Transformation (Flakes or Powder)
-
Goal: Fix soil structure, increase water retention, build organic matter.
-
Rate: 5-8 kg per acre, worked into the soil before planting.
-
Think of it as: The foundational investment in your field’s future productivity.
💧 To Supercharge Your Fertility Program (Powder for Fertigation)
-
Goal: Make your current NPK fertilizer regimen 20-40% more efficient.
-
Rate: 2-4 kg per acre, dissolved in your drip irrigation every 2-3 weeks.
-
Why it works: The fulvic acid acts as a “nutrient taxi,” reducing losses and driving more of what you apply into the plant.
🍃 For a Direct Plant Boost & Stress Response (Powder Foliar Spray)
-
Goal: Overcome a growth stall, improve stress recovery, enhance fruit set.
-
Mix: 1.5 – 2.5 grams per liter of water. Spray in the cool morning.
-
The result: You’re feeding the plant’s internal processes directly, leading to greener, more vigorous growth quickly.
Real Answers for Real Farming Situations
“My soil is tired and compacted. Will this help?”
This is its best use case. The high humic content will actively rebuild soil structure, while the fulvic acid and potassium give the current crop a fighting chance to perform in the meantime. It’s a rescue and renewal plan in one bag.
“Is the ‘up to 40% improved nutrient uptake’ real?”
It’s a well-documented effect of quality fulvic acid. It doesn’t mean you should cut your fertilizer by 40% immediately. It means that for the same amount of fertilizer you apply, more of it will end up in the plant and less will be leached or tied up in the soil. Over time, you can optimize rates downward.
“Can I use it in my organic operation?”
Yes. SIRO-70 is derived from natural Leonardite, a prehistoric organic deposit. It is a cornerstone input for organic and regenerative soil health programs worldwide. Always confirm with your specific certifier.
“Flakes or Powder—which should I choose?”
-
Powder: If you plan to dissolve it for fertigation or foliar sprays. It dissolves almost instantly.
-
Flakes: If your main use is dry broadcast and soil incorporation. They’re less dusty and handle well in a spreader.
“How often do I need to apply it?”
For lasting soil improvement, an annual application is key. For the in-season biostimulant and nutrient efficiency benefits, 2-3 applications (at planting, peak veg, and flowering/fruit set) deliver excellent results.
