The purpose of this research was to collect, codify and taxonomically identify the arthropod individuals found in 45 samples of three farms, under coffee cultivation, planted in organic, conventional and mixed system, in the municipality of Líbano (Tolima, Colombia) during 2014, in an investigation on the exergy. It was obtained that soil arthropods (including mulch and surface leaf litter) of the conventional farm (Type I) had a higher index of diversity than the organic farm and the latter had a higher index than the mixed farm. In spite of this, the organic farm has a greater population of arthropods that double the populations of conventional farms and five times those of the mixed farm, which demonstrates the high interaction between arthropods and the dynamics of organic matter, in the role of transformation of lignocelulitic macromolecules and diversity residue, towards more mineralized forms and in search of the standard C / N ratio of nature.
