Soil organic matter (OM) can be stabilized against decomposition by association with minerals by its inherent recalcitrance and by occlusion in aggregates. However the relative contribution of these factors to OM stabilization is yet unknown. We analyzed pool size and isotopic composition (14C 13C) of mineral-protected and recalcitrant OM in 12 subsurface horizons from 10 acidic forest soils.

Get PriceZeoliteWikipedia
Zeolites are microporous aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt who observed that rapidly heating the material believed to have been stilbite produced large amounts of steam from water that had been adsorbed by the material.
