Premium Coated Fertiliser with up to 20:1 Nitrogen Efficiency

Why settle for average when you can double your pasture response?

Independent NZ trials have shown that humate coated nitrogen delivers up to 20 kg of dry matter per 1 kg of nitrogen applied—nearly double the efficiency of standard urea or Ammo Blends.

That’s not just better growth—it’s better value, better soil health, and better environmental outcomes.

What Makes NitroBlack Boost Different?

• Carbon-coated nitrogen (humates) for improved uptake and reduced losses
• Elemental sulphur for slow steady release
• Magnesium added to support pasture resilience and animal health
• Reduced leaching and volatilisation—protects your investment and your land
• Optimised for NZ soils, especially Canterbury’s light, leach-prone profiles
