“…Chen et al [29] also reported a substantial increase in this fraction in the winter, which was attributed to microbial inactivation under low temperature conditions. Furthermore, Bic-P o was positively correlated with litter and soil C (Table 4), highlighting the potential importance of organic inputs in the contribution to P fertility [45].…”

Thinning is a common management practice in forest ecosystems. However, understanding whether thinning treatment will change the availability of phosphorus (P) in soils, and the effect of thinning on the seasonal dynamics of soil P fractions, are still limited. The objective of the present study was to assess seasonal variations in soil P fractions under different forest thinning management strategies in a Larch (Larix spp.) plantation in northern China. To accomplish this, we examined soil P fractions, soil physical–chemical properties, and litter biomass under control (CK), light (LT), moderate (MT) and high thinning (HT) treatments. Data were collected during the growing season of 2017. We found that most P fractions varied seasonally at different soil depths, with the highest values occurring in the summer and autumn. When compared to CK, MT enhanced the inorganic P (Pi) concentration extracted by resin strip (R-Pi). Labile organic P (Labile Po), moderately labile P and total P (TP) also increased in both MT and HT treatments irrespective of season. In contrast, less-labile Pi and Po fractions were lower in LT than in CK, especially when examining deeper soil layers. Our results suggest that LT leads to a strong ability to utilize Po and less-labile Pi. Moreover, the effect of thinning did not tend to increase with thinning intensity, P availability was maximized at the MT. Ultimately, we show that MT can improve soil P bioavailability and is recommended in Larix principis-rupprechtii Mayr. plantations of North China. Our results emphasize that the effect of thinning management on soil microenvironment is an important basis for evaluating soil nutrients such as soil P bioavailability.

“…It reached reference values of old‐growth remnants for moderate labile P forms after 6 years, and for labile P forms after 24 years. Other studies have found an increase in P availability over the process of succession in tropical and sub‐tropical forests (see Frizano et al [2003], for an example for the Brazilian Amazon, and Zhang et al [2016] for south China), highlighting the role of OM accumulation in soils and biological activity to recover soil P stocks.…”

Soil phosphorus (P) is a major driver of forest development and a critically limited nutrient in tropical soils, especially when topsoil is removed by mining. This nutrient can be present in soils in the form of different fractions, which have direct consequences for P availability to plants and, consequently, for restoration success. Therefore, understanding how the stocks of different soil P fractions change over the restoration process can be essential for guiding restoration interventions, monitoring, and adaptive management. Here, we investigated the recovery of soil P fractions by forest restoration interventions on bauxite mine sites in the Brazilian Atlantic Forest. We assessed the concentration of different fractions of soil organic and inorganic P at (1) a bauxite mine prepared for restoration; (2) two former bauxite mines undergoing forest restoration for 6 and 24 years; and (3) an old-growth forest remnant. Overall, restored areas recovered levels of labile organic P (P o-NaHCO 3) at 5-40 cm and of moderately labile organic P (P o-NaOH) at different depths, exhibiting concentrations similar to those found in a conserved forest. The use of P-rich fertilizers and forest topsoil may have greatly contributed to this outcome. Some other fractions, however, recovered only after 24 years of restoration. Other inorganic P fractions did not differ among mined, restored, and conserved sites: nonlabile P i (residual P and P-HCl), labile P i (P i-NaHCO 3), and moderately labile P i (P i-NaOH). Forest restoration was able to promote efficient recovery of important soil P fractions, highlighting the value of restoration efforts to mitigate soil degradation by mining.

“…This was thought to be due to enhanced mineralization of soil organic P under the trees. A number of variables could explain the differences between studies, including (a) different degrees of organic material decomposition because of the different ages of restoration or afforestation (De Schrijver et al, 2012; Zhang, Shi, Wen, & Yu, 2016); (b) multi‐species restoration versus single species afforestation (Oelmann et al, 2011) and revegetation of arbuscular mycorrhizal fungi dominated versus ectomycorrhizal fungi dominated plant mixtures (Rosling et al, 2016) resulting in different strategies of P utilisation and P dynamics; and (c) different environmental conditions (dry versus wet climate) (Chen, Condron, & Xu, 2008). Extrapolation of the results of the present study site would suggest that organic P pool in restoration soils will eventually approach the level in the mature forest soil and become stabilised.…”

“…The authors attributed this to the potential release of P from occluded pool by soil biota. In South China, Zhang et al (2016) found an increase in occluded P fraction at a mid‐way (90‐year old) forest successional stage, but a decrease to the late (ca. 400‐year old) successional stage.…”

Soil phosphorus dynamics along a short‐term ecological restoration trajectory of a coastal sandplain forest in New Zealand

et al. 2020

We aim to understand the impact of ecological restoration on soil biogeochemistry, and the interrelationship between vegetation and soil phosphorus. In a study of two different‐aged soils in coastal New Zealand, soils are described along a transition from abandoned agricultural pasture, through 6‐year old restoration plots, towards forest fragments that have been largely undisturbed for 75 and 166 years. Soil biogeochemistry varied spatially along this restoration trajectory; there were profound changes in surface soil, but little impact on deeper soil horizons. In the early stages, soil organic matter accumulation and decomposition, and increasing demand of N from fast‐growing plants corresponded with rapid nutrient mineralization. Loss of soil total P, an increase of occluded P, and the increasing importance of soil organic P as soils weathered and aged, supported conceptual models of longer‐term soil pedogenesis. There was no evidence that the success of the establishment of plants varied across the site, but this is a first report of vegetation establishment during ecological restoration markedly impacting soil P dynamics and biogeochemistry.
