Summary

The aim of this work was to discover the influence that parent rock can have on the mineralization of organic matter and to analyse the importance that this could have on forest food sources. For this purpose, under laboratory conditions we analysed the mineralization of carbon, nitrogen and phosphorous from the soil of 20 different plantations of pinus insignis. The highest carbon mineralization rate was measured in soils located on limestone and the lowest on those located on sandstone. The greatest influence on carbon mineralization was produced by the C/N ratio and the pH and phosphorous mineralization appeared to be related to foliar phosphorous.
