FERTILIZANTE ALTERNATIVO A PARTIR DE CINZAS DE BIOMASSAS: UMA BREVE ANÁLISE BIBLIOMÉTRICA VIA SCOPUS

Abstract

The present work aimed to identify and analyze the international scientific research regarding the application of biomass ash in agriculture. To this end, the Elsevier Scopus database and its tools were used as a bibliometric resource, where articles and reviews containing in their title, abstract, or keywords the terms ash, biomass, fertilizer, amendment, and soil, published between 1985 and 2021, were selected. A total of 108 articles were identified, of which 29 were published between 1985 and 2014 and 79 between 2015 and 2021. The increase in the number of publications on this subject in the last seven years is possibly related to the goals set by the Paris Agreement in 2015, which aims to reduce greenhouse gas emissions by replacing fossil fuels with renewable energy sources. Among them, biomass stands out, which has directly contributed to the increasing production of ash and, consequently, has stimulated scientific research on ways to reuse this residue and its effects. Besides agronomic efficiency, the bibliometric analysis revealed that scientific research has focused on the evaluation of environmental impacts caused by the ash application and the search for technological routes for the optimization of its use. The United States, India, and Spain have the largest number of publications on the subject; however, the University of Copenhagen, Denmark, the University of Aveiro, Portugal, and the University of Life Sciences in Poznań, Poland, are the institutions with the largest number of published articles on the subject. Regarding the journals with the largest number of scientific publications, the Science of the Total Environment, Environmental Science and Pollution Research, and Journal of Elementology stand out, which reflects the relations of the subject studied with the areas of environmental, agricultural, and biological science. Keywords: Mineral residue; recycling; agriculture; scientific research.
