KLANZ® Vulkagran G

Vulkagran G is a sustainable soil conditioner consisting of zeolite and volcanic rock. It ensures optimum and long-term growth conditions for lawns after scarifying/aerification.


Vulkagran G stores nutrients and water, regulates the pH value, brings air into the soil, inhibits fungus growth and increases the shear strength of the lawn. Vulkagran is also ideal as a high-quality aggregate to mix into substrates.
