Abstract
The Brazilian Congress of Soil Science (Congresso Brasileiro de Ciência do Solo - CBCS) is the oldest soil science event in South America. The CBCS had 29,643 participants and 23,621 publications in 30 thematic areas between 1947 and 2017. There were only five editions of the CBCS (1947-1979) in which Soil Fertility did not produce the highest number of papers. Standardization of Soil Study Methods and Representation/Soil Teaching was the most prolific in one year, and Soil Genesis, Morphology, and Cartography produced the most papers in the other four years. Subsequently, the area renamed as Soil Fertility and Plant Nutrition had the highest number of papers. By grouping papers into the scientific divisions of the Brazilian Society of Soil Science (Sociedade Brasileira de Ciência do Solo - SBCS), we verify that the division of Soil Use and Management had the most papers in most congresses. In 2017, the number of papers and the number of male researchers in the Brazilian National Council for Scientific and Technological Development were associated for each thematic area. The trends in CBCS publications were influenced by the natural and historic-economic characteristics of the country, in addition to changes that occurred in SBCS, universities, research institutes, and legislation.
Highlights
The first scientific studies of soils in Brazil were carried out from the nineteenth century onwards, in research institutes and agricultural schools
Regarding some other national soil science events, we found that in Argentina (AACS 2018) and India (ISSS 2017) most of the papers occurred in the division of Soil Use and Management, with 67 and 64%, respectively
The present study contributes to the understanding of Brazilian soil science development by revealing trends in 70 years of CBCS publications, in addition to exploring its association with the current divisions of SBCS and CNPq research productivity fellows
Summary
The first scientific studies of soils in Brazil were carried out from the nineteenth century onwards, in research institutes and agricultural schools. At the beginning of the following century, the development of soil science took place, due to the foundation of new research institutions and departments specializing in soils in Brazilian universities (Camargo et al 2010). This occurred due to the great expansion of soil science worldwide, culminating in the birth of the International Society of Soil Science (currently known as the International Union of Soil Sciences - IUSS) in 1924 (van Baren et al 2000). Since 1960, soil science has had an important boost in Brazil, due to the establishment of departments and postgraduate programs in soil science at several
