ABSTRACT A critical analysis of publications on soil fertility was carried out using data from Scopus database for the period of 2007–2016. A total of 16,612 articles were found relating to soil fertility. An exponential increase was evident from the review of published literature and scientists involved in the soil fertility research also increased over period of time. The journals Soil Science and Plant Nutrition and Acta Ecologica Sinica were major publishers of the soil fertility research. Giller K. E. from Wageningen University, The Netherlands was a major contributor followed by Salvati L. of Centro Per Lo Studio Delle Relazioni Piñata-Suolo, Italy. China was the most productive country with 3323 articles. Cluster analysis of author-supplied keywords showed five clusters, namely, desertification, soil organic carbon, plant nutrition, nitrogen, and geostatic. This work will be useful to researchers to know the trends in soil fertility research.
