The objective of the research was to identify the groups of soil mesofauna in farms of six municipalities of Norte de Santander before planting polyculture plots. A non-experimental qualitative and quantitative study was carried out where the soils of 15 farms in each municipality were sampled to identify the taxonomic groups of the edaphic mesofauna. The Berlese-Tyllgren funnel extraction method was used to separate and quantify individuals by families and orders. The soil mesofauna in the six study municipalities included members of between two and six classes corresponding to Arachnida, Diplura, Entognatha, Insecta, Malacostraca and Symphyla, with a greater number of families for Arachnida in all municipalities. In general, the soils of the farms of these municipalities are not considered very disturbed given the number of orders and families present with different functions in the edaphic trophic chain.
