Zeolite is a natural super porous mineral (part of a group of hydrated alumino silicates). It carries a negative charge balanced by freely moving cations with positive charges. this provides an ideal trap for positive cations like nitrogen rich ammonium and potassium which are then released when demanded by plants. Zeolite:

• Enables better plant growth
• Improves the efficiency and value of fertiliser
• Improves water infiltration and retention
• Improves yield
• Retains nutrients for use by plants
• Improves long term soil quality
• Reduces loss of nutrients in soil
• Marginally alkaline and its use with fertilisers can help buffer soil pH levels thus reducing the need for lime applications.
