Double Superphosphate (DSP): High-Yield Phosphorus Precision for Demanding Soils & Crops

Unlock concentrated phosphorus power with our advanced DSP granules (32-40% P₂O₅ + 12-15% S + 18% Ca). Engineered for low-sulfur soils and high-value crops, it delivers 60% more plant-available phosphorus than traditional SSP while maintaining critical sulfur nutrition. ISO 17025 certified for global farming innovation.

I. Scientific Breakthrough Benefits

  • Acid Soil Optimizer:
    Free phosphoric acid dissolves fixed aluminum-P → ↑50% P availability in pH<5.5 soils
  • Sulfur Intelligence System:
    12-15% sulfate-S prevents “hidden hunger” in crucifers & legumes → ↑35% oil in canola
  • Root Force Multiplier:
    Water-soluble orthophosphate ↑40% root hair density in 10 days
  • Economic Revolution:
    25% lower logistics cost per unit P₂O₅ vs. SSP

II. Precision Application Mastery
Sulfur-Deficient Soils (Brassicas/Pulses):

  • 300-350kg/ha pre-plant banding
  • Critical Timing: 3 weeks before sowing
  • Result: ↑28% pod formation | ↓100% sulfur deficiency symptoms
    Acidic High-Fixation Soils (Tropical Crops):
  • Blend with organic matter: 1kg DSP per 4kg compost
  • Benefit: ↑80% P release vs. solo application
    High-Value Horticulture (Potatoes/Tomatoes):
  • Fertigation: 0.4-0.6% solution at tuber/fruit initiation
  • Outcome: ↓95% internal rust spot | ↑22% marketable yield

III. Cutting-Edge Granule Technology

  • Enhanced Solubility:
    90% water-soluble P₂O₅ | Dissolves in 5 minutes (vs. 20+ mins for rock phosphate)
  • Heavy Metal Control:
    Cd≤8ppm | Pb≤20ppm (EU FPR 2019/1009 compliant)
  • Physical Superiority:
    2-4mm granules | >60N crush strength | Dust-free
  • Fluorine Safety:
    Defluorinated process (F⁻<0.25%)

IV. Global Proof of Impact

  • Ukrainian Sunflower Fields:
    ↑19% oil content | 100% elimination of “cupped leaves”
  • Brazilian Cerrado Soybeans:
    5.1t/ha yield in acidic soils vs. 3.8t with TSP (+34%)
  • Vietnamese Coffee Farms:
    ↑31% bean density | Soil pH stabilized at 5.8
  • Egyptian Clover Pastures:
    4X biomass vs. DAP applications

V. Why DSP Beats Ordinary Phosphates

  •  Balanced Nutrition:

P-S-Ca triad perfect for sulfur-sensitive crops

  •  Acid Soil Specialist:

Free H₃PO₄ dissolves toxic aluminum compounds

  •  Cost Efficiency:

$11 saved per hectare vs. TSP-MAP blends

  •  Environmental Leadership:

40% lower carbon footprint than imported TSP

The Phosphorus-Sulfur Synergy Revolution

DSP solves the dual crisis of phosphorus fixation and sulfur depletion:
Soil Rehabilitator – Free acids unlock bound nutrients
Crop Quality Igniter – Convert sulfur into protein and oil premiums
Supply Chain Wisdom – One granule delivers P+S in perfect balance

Where complex blends fail – simplicity wins.
