REPORTS & TESTING

Reports & Testing

Palagonite has been thoroughly analysed and independently tested to confirm its nutrient profile, safety, and effectiveness in soil regeneration and crop support. Scientific backing and laboratory data make it one of the most reliable natural soil conditioners available.

Bioavailability Confirmed by Research

Southern Cross University confirmed that the minerals in Palagonite are readily bioavailable, making them more effective for plant uptake compared to crystalline rock dusts.

Its amorphous volcanic structure gives it high surface area and rapid release characteristics, contributing to fast-acting soil improvements.

Silicon: A Critical Plant Ally

Silicon plays a vital role in plant defence and stress response:

  • Reinforces cell walls with phytoliths — acting as a physical barrier to pests and fungal pathogens

  • Boosts natural defences by increasing lignin, phenolic compounds, and phytoalexins

  • Improves tolerance to heat, drought, frost, and salinity

Studies: Cheng (1982), Jones & Handreck (1967), Epstein (1999), Fawe et al. (2001), Ma & Yamaji (2006)

 

Synthesis of the benefits of Si for crops under various environmental stresses; the mechanical mechanism is due to the presences of phytoliths.

Superior Performance in Soil

  • High CEC of 35 – meaning better nutrient retention and reduced fertiliser loss

  • Safe to use – low dust, no harmful crystalline silica

  • Water retention >65% – excellent for dry soils or sandy conditions

  • Paramagnetism of 600–1300 c/g/s – associated with improved microbial and plant response

Palagonite’s unique volcanic composition and proven nutrient profile make it one of the most comprehensive, effective, and eco-friendly soil solutions available today.
