Abstract

Aim

Anthropogenic phosphorus (P) input profoundly affects carbon (C) and nutrient dynamics in terrestrial ecosystems, which poses a threat to soil health and nutrient sustainability. Litter decomposition is crucial for maintaining soil C and nutrient pools, yet there is a significant knowledge gap regarding the effects of anthropogenic P input on terrestrial litter decomposition.

Location

Terrestrial ecosystems.

Time Period

1985–2024.

Major Taxa Studied

Litter decomposition.

Methods

We conducted a meta-analysis based on 731 observations from 40 peer-reviewed articles to determine the overall effects, patterns and primary predictors of P addition on litter decomposition.

Results

The results showed that P addition increased the activities of β-1,4-glucosidase (BG) and β-1,4-N-acetylglucosaminidase (NAG) during decomposition and accelerated the degradation of lignin and cellulose and the release of litter C. This resulted in a 6.63% increase in litter mass loss. The positive effect of P addition on litter mass loss was further amplified when combined with N addition. In addition, the patterns varied depending on P fertiliser type (e.g., Ca(H₂PO₄)₂, NaH₂PO₄, and KH₂PO₄), P addition level (e.g., < 5, 5–10 and > 10 g P m⁻² year⁻¹), experimental duration (e.g., < 12, 12–24 and > 24 months), litterbag mesh size (e.g., < 0.5, 0.5–2 and > 2 mm), litter type (e.g., leaf, stem and root), climate zone (e.g., tropical and temperate), and ecosystem type (e.g., forest, grassland and wetland). Model selection analysis showed that background soil pH was the primary predictor driving litter decomposition in response to P addition.

Main Conclusions

Our results highlighted that P addition promoted the degradation of organic C, lignin, and cellulose and accelerated the process of litter decomposition. Moreover, the patterns and primary predictors (e.g., backgroud soil pH) are critical for accurately understanding how anthropogenic P input influences these processes.

磷添加对陆地凋落物分解的影响、模式及预测因子

目的人为磷输入严重影响陆地生态系统碳(C)和养分动态，对土壤健康和养分可持续性构成威胁。凋落物分解对维持土壤C和养分库至关重要，但关于人为P输入对陆地凋落物分解的影响存在明显的知识空白。陆地生态系统。时间周期1985-2024。主要分类群研究凋落物分解。方法基于40篇同行评议文章的731项观察结果进行meta分析，以确定磷添加对凋落物分解的总体效应、模式和主要预测因子。结果表明，添加磷提高了凋落物分解过程中β-1,4-葡萄糖苷酶（BG）和β-1,4- n -乙酰氨基葡萄糖苷酶（NAG）的活性，加速了木质素和纤维素的降解和凋落物c的释放，凋落物质量损失增加了6.63%。添加P与添加N对凋落物质量损失的正向作用进一步放大。此外，该模式还取决于P肥类型（如Ca(H2PO4)2、NaH2PO4和KH2PO4）、P添加水平（如<； 5、5 - 10和>； 10 g P m−2年−1）、实验持续时间（如<； 12、12 - 24和>； 24个月）、垃圾袋网尺寸（如<； 0.5、0.5 - 2和>； 2 mm）、凋落物类型（如叶、茎和根）、气候区（如热带和温带）和生态系统类型（如森林、草地和湿地）。模型选择分析表明，背景土壤pH值是影响凋落物分解的主要预测因子。研究结果表明，添加磷促进了有机C、木质素和纤维素的降解，加速了凋落物的分解过程。此外，模式和主要预测因子（例如，背景土壤pH值）对于准确理解人为P输入如何影响这些过程至关重要。

期刊介绍： Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
