You know the signs. Those older leaves turning a telltale yellow between the veins, while the veins themselves stay stubbornly green. It’s classic magnesium deficiency, and it’s silently robbing your plants of their photosynthetic power. Sure, you could reach for the old bag of Epsom salt. But what if there was a smarter, more effective solution that not only fixes the deficiency but also strengthens the plant at the same time?
That’s Siro Chelate Mg. It’s a different kind of magnesium supplement. We’ve taken 6% pure Magnesium and bound it to 25% Free Amino Acids in a 100% soluble powder. The result isn’t just a nutrient—it’s a two-part recovery system for your crops.
The Problem with Ordinary Magnesium (And Our Fix)
Magnesium sulfate (Epsom salt) works… until it doesn’t. In the soil, it can quickly react with other elements like phosphorus or carbonates and become “locked up,” unavailable to your plants. In a spray tank, it can form precipitates. You’re applying it, but your crop isn’t getting it.
Our amino acid chelation technology solves this.
Imagine the magnesium ion is given a protective escort—the amino acid molecule. This escort:
-
Shields it from chemical reactions in the soil or spray mix.
-
Delivers it directly to the root or leaf surface.
-
Hands it off efficiently to the plant for uptake.
This means Siro Chelate Mg is up to 5-7 times more efficient than an equivalent application of magnesium sulfate. You use less, and you see results faster.
The “Bonus” Your Plants Didn’t Know They Needed
Here’s the real advantage: that amino acid “escort” isn’t discarded after delivery. The 25% Free Amino Acids are absorbed by the plant as a powerful biostimulant.
-
Energy Savings: The plant uses these ready-made amino acids to build proteins, saving huge amounts of internal energy.
-
Stress Buffer: This saved energy is diverted to help the plant cope with heat, drought, or disease pressure.
-
Enhanced Metabolism: A healthier, less-stressed plant is simply better at using all nutrients, including the magnesium you just applied.
So you’re not just correcting a yellow leaf; you’re creating a greener, more resilient plant.
How to Use It: Fast Fix or Steady Supply
🍃 For a Rapid Foliar Fix (The Quickest Solution)
This is the fastest way to green up deficient plants. The chelated form is absorbed in hours.
-
Mix: 2.0 – 4.0 grams per liter of water.
-
When to Spray: The moment you see interveinal chlorosis on older, mature leaves. Also excellent as a preventative during high-demand stages: pre-flowering and early fruit development.
-
Frequency: Spray every 10-14 days until the yellowing stops and new growth is deep green.
💧 For Soil or Drip Application (Preventative & Systemic)
Ideal for known magnesium-deficient soils or as part of a balanced fertigation program.
-
Rate: 3.0 – 6.0 kg per hectare.
-
Method: Simply dissolve the fine powder in your irrigation tank. It won’t clog lines.
⚠️ A Quick Mixing Note: Its near-neutral pH (7-9) makes it very leaf-safe and compatible with most inputs. However, if you’re mixing with a strongly acidic product, always do a quick jar test first to be sure.
Which Crops Show the Biggest “Wow” Factor?
All plants need magnesium—it’s the central atom in the chlorophyll molecule. But some are especially hungry for it:
-
High-Value Fruits: Citrus, tomatoes, peppers, grapes.
-
Root & Tuber Crops: Potatoes, sugar beets.
-
Field Crops: Corn, cotton, and legumes.
-
Ornamentals: Roses, azaleas.
If the crop is known for magnesium deficiency or if you’re pushing for maximum yield and quality, this is your product.
Honest Answers to Your Questions
“Is this really better than Epsom salt?”
For a soil with any complexity or a foliar application where you need certainty of uptake, yes, decisively. Epsom salt is a cheap commodity with low efficiency. Siro Chelate Mg is a precision tool with high efficiency and added benefits. It’s the difference between throwing a bucket of water at a fire and using a pressurized hose.
“Can I use it in my hydroponic setup?”
Absolutely. In fact, it’s ideal. Its 100% solubility and stable, chelated form prevent nutrient lock-out in your system, providing a clean, reliable magnesium source.
“What about for organic farming?”
If the amino acids are plant-derived via enzymatic hydrolysis (which ours are), many organic programs allow it. The final authority is always your specific certifier—check with them and we can provide supporting documentation.
“How do the amino acids actually help?”
They do double duty. First, they’re the “smart carrier” for the magnesium. Second, once inside the plant, they act as a direct energy source and metabolic stimulant, making the whole plant function better. It’s correction + revitalization.
Built for Growers Who Pay Attention
Siro Chelate Mg is produced by Shanxi Jinfeng Biotechnology for growers who notice the yellowing leaves and understand that a micronutrient deficiency isn’t just a cosmetic issue—it’s a bottleneck on their entire yield and quality potential.
This product is for the farmer who is done with guesswork and waste. It’s for achieving that deep, healthy green color that is the universal sign of a thriving, productive plant.
Stop treating magnesium deficiency. Start treating the plant. Choose Siro Chelate Mg.
