Tired of wrestling with dusty powders that coat your equipment—or worse, clog your expensive drip lines? You know humic acids are a game-changer for soil and plant health, but the mess and hassle can make you think twice.
Siro-70 WSG solves that. We’ve taken the unparalleled benefits of high-purity humic substances and packed them into a revolutionary form: Water-Soluble Granules (WSG). This means no dust, no clumps, and no more guessing—just clean, consistent, and clog-free performance from the bag to the root zone.
Why Granules Beat Powder Every Time (Especially This One)
Let’s be honest: most humic acid powders are a hassle. They create a cloud of dust, they can refuse to dissolve fully, and they’re a nightmare for precision equipment.
Our 2–4 mm granules are different by design:
-
Dust-Free & Safe: Open the bag without a cloud. Your lungs, your clothes, and the inside of your spray cab will thank you.
-
Precision-Metered: Each scoop or auto-doser gets the same amount. No more settling or inconsistent concentration in your tank.
-
Instant Dissolution: They hit the water and vanish within minutes, leaving a rich, dark solution with no residue to clog filters, nozzles, or emitters. This makes it the only humic product we confidently recommend for drip irrigation.
What’s Inside: The 70% Difference
The “70” isn’t just a number—it’s a statement of purity. While many products are diluted with fillers, Siro-70 WSG is a concentrated engine of soil biology and chemistry.
-
70%+ Humic Acids: The workhorse. This rebuilds soil structure, turning hardpack into a crumbly, aerated sponge that holds water and nutrients.
-
5% Fulvic Acids: The superstar shuttle. These smaller molecules penetrate roots and leaves, chelating nutrients and carrying them directly into the plant.
-
10% Potassium (K₂O): The quality booster. This isn’t an afterthought; it’s integrated to support stress tolerance, fruit development, and sugar transport.
Together, they don’t just feed the plant—they activate the entire growing system.
The Alkaline Advantage: More Than Just a Number
With a pH of 9–11, this product serves a dual purpose. First, it dissolves instantly and completely. More importantly, it acts as a gentle soil conditioner for acidic fields. It helps neutralize low-pH soils, unlocking nutrients like phosphorus that were previously “locked up” and unavailable to your crops.
How to Use It: Simplicity Itself
💧 For Drip Irrigation & Fertigation (The Ideal Method)
-
Rate: 3–5 kg per hectare.
-
How: Dump the granules directly into your irrigation tank. They’ll dissolve as the tank fills. Run your system as normal.
-
Frequency: Every 3-4 weeks during the growing season to continually feed soil biology and enhance your regular fertilizer program.
🍃 As a Foliar Spray (For a Quick Boost)
-
Mix: 2–3 grams per liter of water. That’s about half a teaspoon per gallon.
-
When: At key stress or growth transition points: pre-flowering, post-transplant, or after a weather event.
-
Pro Tip: The clean solution won’t leave gunk in your sprayer. Filter and nozzle life is extended.
🌱 For Soil Application or Hydroponics
-
Soil: Broadcast 8–12 kg/hectare and incorporate for a season-long foundation.
-
Hydroponics/Soilless Mix: Add 0.5–1.0 g per liter to your nutrient reservoir. It stabilizes the solution and improves nutrient availability.
Honest Answers to Practical Questions
“Powder is cheaper. Why should I pay for granules?”
Consider the true cost: time spent cleaning equipment, wasted product from dust and clumping, the risk of ruining a drip system, and inconsistent results. The granules’ efficiency, cleanliness, and reliability save you money and headaches in the long run.
“Will it really not clog my drip lines?”
This is our hallmark. The ≥98% solubility is key. It forms a true solution, not a suspension. We’ve designed it specifically for low-volume irrigation. Always use a filter (as you should with anything), but you won’t find sludge at the bottom of your tank.
“Is it organic?”
It is derived from 100% natural Leonardite ore. It is widely accepted in organic programs globally, but final approval always rests with your specific certifying agency.
“Can I mix it with my other liquid fertilizers?”
Yes, it’s highly compatible. It often improves the performance of your NPK or micronutrient blends by chelating them. The golden rule remains: do a small jar test first when trying a new combination.
“What’s the shelf life?”
Store it in a dry place. The sealed, lined bag will keep it stable and free-flowing for 2 years.
