“…On the one hand, rock weathering and litter P input are the two major sources of soil P (Brandtberg et al 2010;Celi et al 2013;Zhang et al 2021b). For example, P released from litter can integrate into soil organic P pool (Brandtberg et al 2010;Francos et al 2023). Nonetheless, in old forests, litter P input is key for maintaining soil P concentration (Celi et al 2013;Peng et al 2023).…”

“…Moreover, the P recycle (e.g., plants P returns to soil via litter-fall) and its balance among plants, litter, and soil continuum controls the dynamics of soil P fractions (Peñuelas et al 2011;Strukelj et al 2017;Zhu et al 2021), which increases the unpredictability of soil P responses to stand development. Multiple potentially biogeochemical mechanisms can explain the dynamics of soil P during stand development, including: i) the accumulative plant P uptake increases with stand development due to the increase in plant biomass, resulting in a lower soil P concentration (Vu et al 2007;Zhu et al 2021); ii) the changes in litter production and its P concentration during forest stand development alters litter P input (Brandtberg et al 2010;Francos et al 2023;Richardson et al 2008);…”

Background and Aims : Soil phosphorus (P) regulates plant productivity. However, the medium to long-term time-scale effects of reforestation on the P recycle of plants, litter, and soil continuum, thus regulating soil P storage, especially deep-soil P fractions dynamics, are unclear. Methods We determined soil (0 ~ 100 cm) P fractions, root and leaf N/P ratio, leaf-litter P concentration, and biogeochemical drivers in 32-, 45-, and 60-year-old Pinus massoniana reforestations in southwest China. Results The storages of soil labile, moderately labile, and occluded P in the 45- and 60-year stands were lower than the 32-year stand. The concentrations of NaHCO3-Pi, NaHCO3-Po, and total labile P in top-soil were lower while those in sub- and bottom-soil were not significantly in the 45- and 60-year stands compared to the 32-year stand. The concentrations of all soil layer NaOH-Po and total moderately labile P were lower in the 45- and 60-year stands than the 32-year stand. The concentrations of all soil layers C.HCl-Pi and total occluded P were lower in the 60-year stand than the 32-year stand. The leaf N/P ratio and top-soil C/P ratio and acid phosphatase were higher and the leaf-litter P concentration was lower in the older stands. Conclusions P. massoniana secreted more acid phosphatase and increased leaf P resorption to compensate for the drop in soil P-availability with stand age, which in turn decreased leaf-litter P input and thus resulted in a depletion of soil P. Overall, our results highlighted that P limitation increased with stand maturity in P. massoniana reforestations.

“…In addition to summer aridity, torrential fall rains increase the risks associated with forest fires [11]. Thus, the rainy season, which generally follows the dry season, can erode large amounts of soil, especially if it has experienced the combustion of organic matter, leading to increased soil fragility, nutrient runoff, and soil microbiota losses [6,12]. Some of the causes of the increased severity of forest fires in the Mediterranean ecosystem include:…”

Wildfires are a common phenomenon in Mediterranean environments. This study seeks to synthesize the main results of existing studies from the last decade on this topic and to highlight the need for managing soil impacted by wildfires in the Mediterranean environment. Researchers have found that the impact of fire during a forest fire on the soil, and the subsequent consequences on soil ecosystem services and functions, is great and produces negative consequences for the soil. The physical, chemical, and biological properties of soil have been extensively analyzed, and a very high number of studies during the last ten years have been performed on different study areas with a common component: the Mediterranean ecosystem. However, the effects of these fires on the multifunctionality of the soil itself, ecosystem services, and soil functionality, which they provide to humans, have not. It is therefore essential to know the impact of fires in a fire-prone ecosystem such as the Mediterranean one on the soil and how these services and functions are affected. In this way, the decision can be taken to carry out restoration measures, especially after very severe forest fires and if the recurrence is high. This conclusion is even more important in the context of global change in which more severe and recurrent fires are expected, and therefore actions to be considered are expected to be more necessary to avoid land degradation, as many of the studies compiled here have shown.
