PASP-Mg (Polyaspartic Magnesium) | The Biodegradable Way to Prevent Magnesium Deficiency
PASP-Mg (Polyaspartic Magnesium) | The Biodegradable Way to Prevent Magnesium Deficiency
Eco-Friendly Magnesium Nutrient | Fully Biodegradable | Liquid & Powder Available | Customization Ready
Product Overview
PASP-Mg is the magnesium salt of polyaspartic acid—a modern chelated magnesium fertilizer that delivers active magnesium to crops while being fully biodegradable. It holds magnesium ions in a stable, plant-available form, preventing them from being fixed in soil and ensuring efficient absorption through roots and leaves.
What makes it different: it works effectively, breaks down naturally in the environment, and even provides energy for plant growth as its breakdown products (aspartic acid and fumaric acid) feed into the plant's natural metabolic cycle.
Supplied as a solid powder or a liquid solution—same performance, different format. Choose what fits your operation.
Manufactured by Hebei Think Do Chemicals Co., Ltd, with flexible customization including packaging, labeling, concentration adjustments, and OEM/ODM services. Full export documentation (COA, MSDS, TDS, commercial invoices, packing lists) accompanies every shipment.

Key Benefits
For crops:
- Prevents and corrects magnesium deficiency—reducing interveinal yellowing (chlorosis) on older leaves, poor photosynthesis, and low yields
- Boosts photosynthesis—magnesium is the central atom in chlorophyll, directly powering plant growth and sugar production
- Enhances fertilizer efficiency—works with urea or compound fertilizers to boost nutrient uptake
- Strengthens stress resistance—helps crops fight drought, cold, and disease pressure
- Improves yield and quality—increases fruit sugar content, grain weight, and crop uniformity
- Fully biodegradable—breaks down into aspartic acid and fumaric acid, providing extra energy for plant growth
- Acts as a heavy metal passivation agent—helps immobilize toxic metals in contaminated soils
- Can be applied as foliar spray, drip irrigation, or mixed with water-soluble fertilizers
For the environment:
- Unlike traditional chelators like EDTA that persist for years, PASP-Mg degrades completely in soil and water
- Leaves no toxic residues, safe for long-term soil health and beneficial organisms
How to Use
For foliar spray, dilute liquid PASP-Mg 500 to 800 times with water. For powder, dissolve in warm water to make a stock solution first, then dilute. Apply when magnesium deficiency symptoms appear (yellowing between leaf veins on older leaves) and during fruit or grain development.
For drip irrigation, apply 1.5–3.0 liters per acre (liquid) or 0.5–1.0 kg per acre (powder) every 15 to 20 days.
For mixing with NPK fertilizers, blend directly with urea, compound fertilizers, or water-soluble blends to improve overall nutrient availability.
For soil heavy-metal passivation, use higher rates to immobilize toxic metals in contaminated farmland.
> Pre-dissolve powder in warm water before mixing. Avoid mixing with strong acids (pH < 3) or strong alkalis (pH > 11). Always test compatibility before large-scale mixing.
Environmental Profile
PASP-Mg is readily biodegradable—its polyaspartic backbone breaks down completely in soil and water within months. Unlike EDTA-based chelates that persist in the environment for years, PASP-Mg decomposes into simple, harmless compounds. Its breakdown products—aspartic acid and fumaric acid—are natural plant metabolites that can be absorbed by crops as an additional energy source, supporting stronger growth and better yields. Low toxicity to plants and aquatic life makes it a responsible choice for sustainable farming.

FAQ
Q: What makes PASP-Mg different from EDTA-Mg?
A: PASP-Mg chelates magnesium effectively but is fully biodegradable—EDTA-Mg persists in soil and water for years. PASP-Mg is the greener choice.
Q: Why is magnesium so important for crops?
A: Magnesium is the core element of chlorophyll—without it, plants cannot photosynthesize, resulting in yellow leaves and low yields.
Q: Can PASP-Mg be mixed with fertilizers?
A: Yes. It blends well with urea, NPK, and water-soluble fertilizers.
Q: Can PASP-Mg be used for heavy metal soil remediation?
A: Yes. It acts as a heavy metal passivation agent, immobilizing toxic metals in contaminated soils.
Q: Liquid or powder—which should I choose?
A: Liquid saves labor and is ready to use. Powder costs less to ship. Performance is identical. Shelf life is 12 months for both.
Q: Is PASP-Mg suitable for organic farming?
A: It meets green chemistry standards due to full biodegradability. Organic certification varies by region—consult your local certifier.
Q: Is packaging customization available?
A: Yes. Hebei Think Do Chemicals Co., Ltd provides custom packaging, labeling, concentration adjustments, and OEM/ODM services.
