“…2 ), which can be explained by the accumulation of soil total P in the topsoil 28 , 29 . The large-scale precipitation and temperature on the uppermost soil layer can enhance bedrock and soil chemical weathering rates 23 and stimulate soil total P accumulation in the topsoil profile 30 . Our results also demonstrated, via random forest models and linear regression analyses, that the effect size and importance of climate factors for topsoil layers were higher than those for subsoil layers.…”

“…Previous studies have suggested that the vertical distribution patterns of soil total P may also be explained by the effect of biotic and abiotic factors and the multiple pathways resulting in soil layer differences 30 . Soil properties 30 , plant litter inputs 32 , root system secretion 33 , enzyme activities 34 , and microbial decomposition 35 are known to decrease with increasing soil depth; these factors are ultimately dependent on large-scale climate patterns, because climate affects the distribution of soil total P by controlling the rates of both geochemical weathering and biological activities 30 , 36 .…”

This may be due to the global variability in soil age and development, climatic conditions, and topographic heterogeneity 30 , 37 , 38 . Soil total P concentration among the different soil depths showed a similar decreasing pattern from north to south in China’s forest ecosystems, which once again indicates that climate is one of the main factors affecting the soil total P distribution at large spatial scales 20 , 24 , 39 .…”

Phosphorus (P) is an important element in terrestrial ecosystems and plays a critical role in soil quality and ecosystem productivity. Soil total P distributions have undergone large spatial changes as a result of centuries of climate change. It is necessary to study the characteristics of the horizontal and vertical distributions of soil total P and its influencing factors. In particular, the influence of climatic factors on the spatial distribution of soil total P in China’s forest ecosystems remain relatively unknown. Here, we conducted an intensive field investigation in different forest ecosystems in China to assess the effect of climatic factors on soil total P concentration and distribution. The results showed that soil total P concentration significantly decreased with increasing soil depth. The spatial distribution of soil total P increased with increasing latitude and elevation gradient but decreased with increasing longitude gradient. Random forest models and linear regression analyses showed that the explanation rate of bioclimatic factors and their relationship with soil total P concentration gradually decreased with increasing soil depths. Variance partitioning analysis demonstrated that the most important factor affecting soil total P distribution was the combined effect of temperature and precipitation factor, and the single effect of temperature factors had a higher explanation rate compare with the single effect of precipitation factors. This work provides a new farmework for the geographic distribution pattern of soil total P and the impact of climate variability on P distribution in forest ecosystems.

“…Besides spatial patterns of soil P fractions, their dominant drivers have also attracted considerable attention (Garcia‐Velazquez et al., 2020; Hou, Chen, et al., 2018; Luo et al., 2021; Martin‐Sanz et al., 2021). However, previous studies were mainly confined to climatic and edaphic properties (Hou, Chen, et al., 2018), and little information is available about how soil microbial properties (e.g., microbial biomass, community composition and phosphatase activity) and minerals (e.g., Fe/Al‐(hydr) oxides and carbonate minerals) regulate various soil P fractions over broad geographic scale (Martin‐Sanz et al., 2021).…”

The storage and dynamics of various soil phosphorus (P) fractions could determine soil P availability, and thus regulate terrestrial carbon cycle and its feedback to climate warming. However, little evidence is available about patterns and drivers of soil P fractions in alpine ecosystems which could play a crucial role in terrestrial carbon cycle. Here we evaluated various topsoil P fractions and their determinants in Tibetan alpine grasslands using systematic measurements along a 3,000 km transect. Our results showed that topsoil P concentrations in Tibetan alpine grasslands were higher or equivalent than those in temperate and tropical‐subtropical ecosystems. Our results also revealed distinct drivers among various soil P fractions: microbial properties and soil pH were dominant drivers of labile P and secondary mineral P fractions, respectively. Mineral properties were key determinants of occluded P and organic P fractions, whereas primary mineral P fraction was largely predicted by precipitation and mineral properties. The large‐scale evidence obtained in this study offers new insights for better predicting the trajectory of soil P availability and its interactions with ecosystem carbon cycle in alpine ecosystems under changing environment.

“…Therefore, changes in the fractions of soil P in bamboo‐chicken farms can largely determine the soil P availability, which in turn affects microbial community structure and bamboo forest production. The dynamics of P fraction content depends on various factors, such as soil texture, climatic environment, microorganisms, and land use (Maharjan, Maranguit, & Kuzyakov, 2018; Velázquez et al, 2020). Previous studies have shown that overgrazing may hinder the mineralization of phosphorus (Ford, Roberts, & Jones, 2016) and reduce its solubility (Sigua, Chase, & Albano, 2014).…”

Bamboo‐chicken farming (BCF) is a popular bamboo complex management model in Southeast Asia. However, the effects of BCF on phosphorus (P) availability and associated soil microbial communities remain poorly understood. In this study, we compared the soil properties, P fractions, phosphatase activities, and bacterial community compositions in the surface soil (0–20 cm) of a typical BCF system under different grazing densities [represented as distances of 5, 15, 25, 35, and > 60 m (control site) from the henhouse, respectively]. We observed that total P (Pt) accumulation was more rapid than that of SOC and TN with increasing grazing density. Labile and moderately labile P dominated soil P accumulation under BCF. Resin‐Pi, NaHCO3‐Pi, and 1 M HCl‐Pi increased by 100–233%, 83–183%, and 414–1,314%, respectively, compared with the control. The ratio of labile and moderately labile organic P to the Pt content decreased significantly with increasing grazing density from 38.54% (control) to 17.65% (5 m site). Soil phosphatase activity increased with increasing grazing density, suggesting that BCF effectively promoted the mineralization of soil Po. Inorganic P (Resin‐Pi, NaHCO3‐Pi, and 1 M HCl‐Pi) was positively correlated with Flavobacterium, Pseudomonas, and Arthrobacter but negatively correlated with Burkholderia; this highlights the different functional bacteria involved in P cycling. We conclude that BCF generally increased soil P availability and supply capacity, and the changes in P forms were closely related to changes in soil bacterial community composition. The highly labile P and low C : P ratio under high grazing density conditions may cause soil nutrient imbalance and P leaching.
