“…This suggests that soil acidi cation will further promote changes in soil chemical properties in Wuhan city. It has been reported P is generally lacking in the acidic red soil in central and south of China (Ao et al 2014;Huang et al 2019a;Peng et al 2020). Leaves returns part of P to the tree body before falling in P-poor areas (Du et al 2020;Peng et al 2023), therefore, the similar lower values of litter P and soil P con rmed that the P limitation in urban forests where has more acidic soils.…”

Aims: Reforestation has been considered as an effective way to mitigate the adverse environment impacts from urbanization, while the role of different reforested forests on urban soil is not well known. This study aims to detect the forest soil properties across urban-nonurban gradients and explore whether and how the reforested trees affect urban soil. Methods: We collected soil and litter samples in reforested forests in Wuhan (a megacity in central China), measured their chemical properties, and compared them with the surrounding nonurban forests. We then investigated the effects of three common reforested trees Pinus massoniana, Camphora officinarum and Quercus variabilis on the urban forest soils. Results: We found that forest soils were more acidic but lower of N content in the urban areas than in the nonurban areas. There were significant differences in litter chemical properties (pH, organic C, N, P) among the forests planted with different trees, while only the differences in pH and P were consistent with those of forest soils. Furthermore, the more C. officinarum in an urban forest, the higher the pH in the soils, indicating a potential function of mitigating the soil acidification. Conclusions: Although urbanization changed forest soil chemical properties, the tree species used in reforestation can affect urban forest soils through producing litter with various properties. Therefore, the biological method, i.e. planting appropriate trees will be a natural solution to address the soil problems in urban areas.

“…When pH becomes neutral or slightly alkaline, soil particles become negatively charged, and the mineral surface repels negatively charged organic molecules/colloids containing P, limiting the complexation of these P compounds on the soil mineral surface. Peng et al [90] found that acidification tends to promote soil phosphorus loss into water bodies.…”

“…The flooding conditions will promote the reloss of P from soil to water. Under hydraulic erosion, soil phosphorus released by hydrolysis enters adjacent water along with surface runoff and soil erosion [90]. Xu et al [94] demonstrated that residual P (H 2 SO 4 -H 2 O 2 digestion) decreased by 18-27% in flooded paddy soil compared with aerobic soil.…”

Phosphorus (P) nonpoint source pollution from soil to water is increasing dramatically, leading to the eutrophication of water bodies. Using amendment materials for P retention in soil is a promising strategy for environmental restoration and nonpoint source pollution management. This strategy has attracted significant attention because of its highly effective P retention. This study reviews management strategies of P nonpoint pollution from soil to water, including the basic P forms and accumulation situation in soil and P loss from soil to water. Recent advances in the use of amendment materials, such as inorganic, organic, and composite amendment materials, to mitigate P pollution from soil to water have also been summarized. Environmental risks of reloss of P retention in soil with different soil properties and water conditions have also been investigated. This review improves the understanding of P nonpoint source pollution from soil to water, providing an innovative perspective for the large-scale application of amendment materials to control water eutrophication.

“…Only K01083 (bpp) was positively correlated with AP and TP in NPKGM. A possible mechanism was the phosphate released from soil minerals being easily leached from red paddy soil under high precipitation (Peng et al, 2020), while the organic phosphorus released from milk vetch rotation could remain longer in soil (Zhao et al, 2013), hence we observed a significant positive correlation between K01083 and soil phosphorus content even when the abundance of K01083 was low (Jorquera et al, 2013). In addition, encoding phytases that catalyze the hydrolysis of plant-sourced phytate (Lu et al, 2022) and taxa containing bpp could benefit in soil with greater plant litter input (Liu X. et al, 2022).…”

Legume crop rotation is often adopted in rice cultivation to improve soil productivity. However, little is known about the role of microbes under legume rotation in affecting soil productivity. To elucidate this, a long-term paddy cropping experiment was set up to study the relationship between crop yield, soil chemical properties, and key microbial taxa under a double-rice and milk vetch rotation. Milk vetch rotation significantly improved soil chemical properties compared to no fertilization treatment, and soil phosphorus was a major factor correlated with crop yield. Long-term legume rotation increased soil bacterial alpha diversity and changed soil bacterial community. After milk vetch rotation, the relative abundances of Bacteroidota, Desulfobacterota, Firmicutes, and Proteobacteria increased while those of Acidobacteriota, Chloroflexi, and Planctomycetota decreased. Moreover, milk vetch rotation increased the relative abundance of phosphorus-related gene K01083 (bpp), which was significantly correlated with soil phosphorus content and crop yield. Network analysis showed that taxa of Vicinamibacterales were positively correlated with total phosphorus and available phosphorus, which was a potential taxon contributing to the availability of soil phosphorus stock. Our results indicated that milk vetch rotation could enrich key taxa with latent phosphate-solubilizing ability, increase the content of soil available phosphorus, and finally enhance crop yield. This could provide scientific guidance for better crop production.
