Applications in Agrochemicals
Powdered carrier for fertilizers
Nitrogen Fertilizers
Carrier for urea and ammonium sources: retains NH₄⁺ and reduces ammonia volatilization (He et al., 2002).
Blend with Urea
Clinoptilolite incorporated into urea-fertilized soil reduced NH₃ and N₂O emissions by about 50% (Wang et al., 2025).
Potassium Fertilizers
Clinoptilolite retains K⁺ by cation exchange, favoring its permanence in the root zone (Cataldo et al., 2021).
Controlled NH₄⁺ Release
Natural clinoptilolite adsorbed ammonium to equilibrium in 60 to 120 minutes and released it almost completely in 150 to 200 minutes, indicating potential as a controlled-release fertilizer (Kithome et al., 1998).
* Reference doses. They may be reviewed by qualified professionals, such as veterinarians, agronomists, animal scientists, chemists and food engineers, among others, since professional titles and qualifications vary between countries; local regulatory bodies may also set their own limits.
