Abstract:

The paper aims to understand the research progress and development trend of soil phosphorus availability in China. Based on 2082 literature on soil phosphorus availability in the core collection database of Web of Science, and with the tools of R bibliometrix, CiteSpace, VOSviewer, and Histcite, we used the number of publications, total/average citation frequency and centrality as indicators, to classify and visualize published papers, research strength, research hotspots and subject evolution in the field of soil phosphorus availability research. The results show that the number of publications in the field of soil phosphorus availability is on the rise as a whole, with prominent journals including Plant and Soil, Soil Biology & Biochemistry, and Geoderma. From the perspective of national research strength, China, the United States and Australia are the top three in the total number of published papers. China has published far more papers in this field than other countries, accounting for 29.97%. Up to now, the Chinese Academy of Sciences has published 303 papers, and the number is the most among research institutions. From the analysis of strategic coordinate charts and keywords, we can see that the availability is the core subject of this field. Keywords such as “enzyme activity”, “microbial community”, “phosphorus limitation”, “nitrogen deposition” and “soluble organic carbon” became hotspots in this field from 2018 to 2022. Under the background of environmental factor change, the interaction between soil phosphorus availability and microbial community, enzyme activity, and soil carbon and nitrogen are the forefront of current research, and the interaction among microbial communities, enzymes and nutrients, and interdisciplinary topics will become the focus of future research.

Key words: Web of Science, soil phosphorus availability, strategic coordinate chart, bibliometrics
