RCC is a technical-scientific event promoted by SBCS with the support of several institutions and linked to the Brazilian Soil Classification System (SiBCS). Usually, the event is held with the participation of professionals working in research institutions, higher education and technical services in the area of Soil Science or related, especially those linked to the specialized commissions of Genesis and Morphology, Survey and Classification and Pedometry.

The main objective of the event is the validation and improvement of the SiBCS through in situ correlations between occurrences in the Brazilian territory of soil classes and their geoenvironmental characteristics, their vulnerabilities and potentialities for agricultural use. In this sense, the RCC is distinguished from other soil science events by being conducted along a field trip itinerary, established according to environmental characteristics considered of interest for that objective. The name of these meetings varied over time, but was firmly established in the most recent editions as RCC – Brazilian Meeting of Classification and Soil Correlation. Similarly, the identification of directors / organizers / promoters varied over time, and The SBCS assumed the official character of Promoter since the 10th edition, in 2012, in the Pantanal.

Since the first RCC in 1978, this event has been a mechanism that induces large and important advances in the classification system, embodied in adjustments and improvement of criteria, definition and testing of concepts and procedures, including with regard to laboratory methodologies. In addition, it is a unique opportunity to bring together specialists, professors, researchers and students working in the area of Pedology and Soil Science, promoting greater interaction and expanding interpersonal and institutional communication. It also allows professionals working in other regions to have direct contact with environments different from their reality, contributing to learning in the assessment of vulnerabilities and potentialities for agricultural use, and expanding knowledge about soil management and conservation.

The XIV Meeting of the Brazilian Meeting of Soil Classification and Correlation (RCC) will be held in 2022

Promoted by the Brazilian Soil Science Society (SBCS) and the Midwest Regional Nucleus (NRCO), the XIV RCC will be held in the states of Goiás and Tocantins. The organization and coordination of the event are from the Federal University of Goiás (UFG) and Embrapa Fisheries and Aquaculture (TO), in partnership with Embrapa Solos (RJ).

In addition to these institutions, the event counts on the collaboration of the following partners: Instituto Federal Goiano (IF Goiano), Universidade Federal Rural do Rio de Janeiro (UFRRJ), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), Universidade Federal de Viçosa (UFV), Embrapa Milho e Sorgo (CNPMS), Universidade do Estado de Santa Catarina (UDESC), Universidade Federal Rural de Pernambuco (UFRPE), Instituto Federal de Minas Gerais (IFMG) and Geological Service of Brazil (CPRM).

The observation sites were selected because they presented soils whose current classification deserves further discussion regarding the current criteria, both from the taxonomic point of view and from their agricultural aptitude.

The RCC is expected to be held between October 8 and 15, 2022, a date yet to be confirmed.

RCC 2017/2018

Between September 9 and 16, 2017, the SBCS held the XII Soil Classification and Correlation Meeting (RCC). The event was organized by the Northwest Regional Nucleus of SBCS and organized by Embrapa Rondônia, Embrapa Solos, Federal University of Rondônia, Federal Rural University of Rio de Janeiro, Brazilian Institute of Geography and Statistics (IBGE) and the Geological Service of Brazil, with support from the Rondonia Federal Institute of Education (IFRO). The general coordination was by the researcher Paulo Guilherme Wadt (Embrapa Rondônia) with the support of José Francisco Lumbreras (Embrapa Solos), Lúcia Helena Cunha dos Anjos (UFRRJ) and Francisco de Assis Correa Silva (Embrapa Rondônia).

The XII RCC was divided into two excursions to allow a greater number of participants and give the opportunity for interested parties from various institutions to learn more about the reality of the agricultural production environment and the soils of Rondônia.

The first trip had a total of 84 participants. Of these, 74 are partners of SBCS. Among the participants, 78 enrolled as professionals and six as students.

In the first tour, we visited a soil profile in the municipality of Canutama, in the State of Amazonas, and 13 profiles in Rondônia, distributed among the municipalities of Porto Velho, Ariquemes, Machadinho do Oeste, Ouro Preto do Oeste, Rolim de Moura, Alta Floresta do Oeste, Pimenta Bueno, Colorado do Oeste, Pimenteiras do Oeste and Vilhena.

According to the coordinators, the participants of the RCC had the opportunity to know new environments and evaluate poorly studied soils in the Amazon as a profile with high organic matter content, but without the expression of exchangeable loads (null CEC), a kaolinitic Latosol with auric character and another in which the sorbrico character was discussed; besides a profile with an anthropic horizon (Terra Preta de Índio) still little studied in the state of Rondônia.

The organizers gave the participants a Field Guide with information on the characterization of the soils to be visited, in addition to the history, geodiversity and forest cover of Rondônia. Additional chapters were also made available on the research carried out with these soils (Related research), to support the discussion during the event.

The second tour took place between August 1 and 8, 2018, opening the World Congress of Soil Science (WCSS).

The RCC 2017 was held between 9 and 16 September in Rondônia.

XIII RCC: Maranhão, 2019

SBCS thanks and congratulates all the participants and professors Marlen Barros e Silva (UEMA), Marcelino Silva Farias Filho (UFMA), and José Francisco Lumbreras (Embrapa Solos) for the success of XIII RCC-Maranhão.
