This paper shows the experience of using AGROVOC thesaurus as a basis and model of information and knowledge organization and domain representation applied to soybean and sugar cane agricultural intensification in Brazil. A textual corpus of about 2,5 million of words was compiled and candidate terms extracted automatically for creating an initial hierarchical conceptual map, then compared to AGROVOC terms. The results show the importance of AGROVOC as a resource to organize and represent agricultural information and knowledge, as a reference for creating new terminological products on agriculture, and open new possibilities for enrichment of AGROVOC´s Brazilian Portuguese terminologies.
