"The thesaurus is organized into 17 subject categories, indicated by the 'Subject Category' designation. The subject categories are used to browse the Thesaurus in a specific discipline or subject area. The subject scope of agriculture is broadly defined in the thesaurus, and includes terminology in the supporting biological, physical and social sciences. Biological nomenclature comprises a majority of the terms in the thesaurus and is located in the 'Taxonomic Classification of Organisms' Subject Category. Political geography is mainly described at the country level. The NAL Agricultural Thesaurus includes hierarchical, equivalence and associative relationships among concepts.
