Bedrock lithology and tree species type influence soil nitrogen dynamics in a temperate forest

Original language description

Despite significant progress in studying soil organic carbon (SOC) and nitrogen (N) cycling in temperate forest soils, understanding of how bedrock lithology and tree species type influence these parameters remains tentative. To address this, we collected soil samples from three depth intervals and plant materials from two distinct tree species, beech, and lime, from sites within the Hyrcanian Forests (Iran) underlain by carbonate and intermediate volcanic bedrock. C and N elemental concentrations and their stable isotope compositions (δ13C and δ15N) were determined for bulk soil and four SOM fractions, including free particulate organic matter (FPOM), macroaggregates, microaggregates, silt + clay-sized fractions, as well as leaf litter and fine roots. Results indicated that lithology and tree species had no significant relationship with SOC content and δ13C of various soil fractions. Along with their δ15N values, TN contents of bulk soil, FPOM, macro- and microaggregates covaried with tree species and lithology. Total N content in bulk soils underneath lime trees exceeded that found beneath beech trees (0.43 % vs. 0.36 %). In terms of N turnover, volcanic soils showed significantly higher mean 15N enrichment relative to that observed for carbonate soils. The C and N fluxes observed for different tree species and lithologies revealed a 13C and 15N enrichment trend in the following order: macroaggregates< microaggregates< silt and clay-sized particles. Our results showed that underlying lithology influences C and N dynamics in forest soils, and the analysis of the natural abundance of 13C and 15N provides detailed information on C and N cycling and stabilization pathways in soil aggregates. Our findings demonstrate the importance of lithology as a factor in nutrient cycle estimates for terrestrial ecosystems.
