Bibliometric Analysis of Soil Nutrient Research between 1992 and 2020

Abstract

Soil nutrient balance is related to the interaction mechanism between soil fertilizer, soil water, climate change, and plant capability. This paper provides a perspective from bibliometric analysis based on data from the Web of Science core collection with software tools, including Vosviewer, HistCite Pro, and Citespace, in order to reveal the evolution of research trends in soil nutrients. The results show that publication outputs have increased exponentially from 1992 to 2020. The synthetic parameter of the sum of normalized data (SND), calculated from the default indicators of the bibliometric software tools, was used to rank the overall contribution of journal/authors/institutions/countries. The results demonstrate that Agriculture Ecosystems & Environment, Soil Biology & Biochemistry and Science of the Total Environment are the leading journals in the soil nutrient field. The Chinese Academy of Sciences had the highest total citations and collaborated most closely with other organizations, followed by United States Department of Agriculture (USDA) Agricultural Research Service (ARS) and Agr& Agri Food Canada. In addition, USA, China, and UK are the top three research centers for this topic. Moreover, Ken E Giller, Qirong Shen, and Rattan Lal were the top three authors, while Andrew Sharpley ranked the first depending on citations per publication. In terms of co-occurrence of keyword analysis, the results indicate that nitrogen fertilizer, green manure, and soil population have gained close attention from scholars, while soil amendment of biochar have evolved as a hot topic in recent years. Perspectives on future studies are also given.

Driving Management of Novel Foods: A Network Analysis Approach

“…Trying both tools for the aggregation of keywords, and after having evaluated the results of the two relative different elaborations of the network, it proved appropriate to use full counting, in line with other authors (Arias et al, 2021;Pan et al, 2021;Raboaca et al, 2021), for three reasons.…”

Evolution of Overall Cotton Production and Its Determinants: Implications for Developing Countries Using Pakistan Case

“…Second, those findings also indicate that cotton productivity has a strong inverse relationship with the fertilizer to the cotton crop. Given the importance of balance fertilizer management practices [56], an inverse relationship may be associated with low quality of fertilizer or farmers applying higher doses of chemical fertilizer on cotton crop, less knowledge of fertilizer combinations [57]. Third, the technical efficiency is negatively associated with irrigation; as a result of efficiency analysis, average technical efficiency is about 85 percent over the period.…”

Toprak Organik Karbonu ve Toprak Organik Karbon Stokları üzerine 1970-2021 Yılları Arasında Yapılan Araştırmaların Bibliyometrik Analizi

“…Bibliyometri matematiksel istatistiğe dayalı nicel bir analiz yöntemidir. Belirli bir bilimsel alandaki araştırmaların çarpıcı noktalarının belirlenmesine ve yapılacak çalışmaların eğilimlerini analiz etmek için yaygın olarak kullanılmaktadır (Pan et al, 2021;Sökmen and Nalçaci, 2020;Zhang et al, 2020). Literatür analizi araç olarak, toprak biliminde de popülerlik kazanmakta ve bu alandaki çalışmaların sayısı da artmaktadır.…”

“…Literatür analizi araç olarak, toprak biliminde de popülerlik kazanmakta ve bu alandaki çalışmaların sayısı da artmaktadır. Bu çalışmalara; toprak erozyonu modellemesinin Bibliyometrik analizi (Bezak et al, 2021), 1999'dan 2018'e kadar toprak sağlığı üzerine yapılan araştırmaların bibliyometrik analizi (Y. , 1992 ve 2020 yılları arasında Toprak Besin Maddeleri Araştırmalarının Bibliyometrik Analizi (Pan et al, 2021), CiteSpace'e dayalı çölleşme restorasyonuna ilişkin bibliyometrik analiz (Hu et al, 2021) ve Su koruma ve toprak tutma ekosistem hizmetleri üzerine araştırmaların bibliyometrik analizi (S. örnek olarak verilebilir.…”
