First results of a field experiment in nature reserve Maasduinen, indicate that addition of vulkamin, a zeolite containing clay-mineral, may be more effective in restoring acidified heathlands than addition of dolocal. Vulkamin has the beneficial effect to more strongly decrease N availability in the soil as well as the availability of micro-nutrients resulting in vegetation with a higher C:N ratio and  higher manganese content. Therefore, addition of vulkamin could make heathlands more resistent to ongoing climate change and atmospheric nitrogen deposition (leading to lower C:N ratio causing massive insect plagues) and may prevent manganese deficiency in the foodchain.
