About TerraAMS

TerraAMS is a fully water-soluble fertilizer, specifically designed for fertigation. It delivers essential nitrogen and sulfur in immediately available forms, supporting plant growth across all development stages.

  • Contains 21% ammonium nitrogen (NH₄-N)
  • Supplies 24% water-soluble sulfur trioxide (SO₃)
  • Free from chloride and sodium – suitable for sensitive crops
  • Meets peak nutrient demands during all growth phases
  • Reduces nitrogen losses – ammonium-N is stabilized by clay particles
  • Acidifies alkaline soils, enhancing the uptake of phosphorus and trace elements
  • Sulfur plays a critical role in protein formation and boosts nitrogen use efficiency
  • Suitable for fertigation systems and supplementary foliar application
  • Mixable with most crop protection products and compatible fertilizers

Note: Packaging sizes may vary by region.

Application rates depend on several key variables:

  • Application type (e.g., open/closed fertigation systems, foliar support)
  • Crop type and specific growth stages
  • Yield targets and nutritional needs
  • Soil or substrate characteristics
  • Temperature and climate conditions
  • Crop cycle duration
  • Use only as a supplement to soil application
  • For mature crops and fruit trees during active growth: 1–3% solution
  • For young plants or early growth stages: 0.5% solution
  • Apply during cooler periods to avoid leaf stress
  • Suitable for all irrigation systems (conventional, high-pressure, and low-pressure)
  • Can be applied in constant low concentrations between 0.01% and 0.1%
  • Recommended for use throughout key nitrogen-demanding stages
  • Always follow the manufacturer’s blending instructions
  • Do not mix in the tank with fertilizers containing calcium or magnesium
  • Perform a jar test to confirm solubility before combining with other inputs
  • Conduct a plant-level pre-test before widespread foliar use
