• Effects of simulated nitrogen deposition on soil phosphorus availability and element composition in a phosphorus-limited Mediterranean shrubland (2026) · Frontiers in Forests and Global Change · doi

  The effects of nitrogen addition on key soil elements remain insufficiently understood. There is a lack of knowledge on the impacts of nitrogen deposition on soil phosphorus availability and element composition in phosphorus-limited Mediterranean shrublands. The study aims to address this knowledge gap.

  Most of the results described in the literature were obtained from model laboratory experiments. Natural soil conditions may not confirm the observed effects due to the influence of external factors and the complexity of the soil ecosystem as a whole.

  Soil properties such as soil organic carbon (SOC), nitrogen (TN), phosphorus (PTP), and bulk density (BD) underpin soil fertility and ecosystem functioning, yet the relative importance of factors controlling their long-term states and short-term changes remains poorly quantified.
