ZeoGreen is a natural rock containing as the main crystalline component the zeolitic mineral clinoptilolite, together with minor amounts of mordenite (another zeolite mineral), quartz, clay (smectite) and mica.
ZeoGreen is a hydrous aluminosilicate that is able to freely exchange certain cations. Cationic nutrient ions, such as those of calcium, magnesium, potassium, sodium and particularly ammonia are exchanged in this way.
The Cation Exchange Capacity of ZeoGreen is greater than 120 meq./100g. Only the exchangeable cations can be considered available in agriculture. In the natural state the exchangeable cations of Escott Zeolite are
Na 12
K 4
Ca 85
Mg 18
TOTAL 119 m.eq./100g
