Resumen
[ES] En este estudio se ha procedido al análisis de 10 muestras pertenecientes a los bancales del Eco-huerto de la Universidad de Jaén, para así analizar la comunidad de nematodos existente. A la hora de la extracción y preparación de las muestras, se usó el método de Baermann (1917) y el método de montaje en lactofenol-glicerina (Siddiqi, 1964). A la hora del análisis de las muestras, se ha calculado el índice de madurez de suelo (Bongers, 1990) el análisis de la abundancia relativa, tanto desde el punto de vista taxonómico como el punto de vista trófico. Se han encontrado 36 géneros y 41 especies, obteniéndose que el orden dominante es el de los rabdítidos, compuesto principalmente por los infraórdenes Cephalobomorpha y Tylenchomorpha. En cuanto a los grupos tróficos dominantes son los bacteriófagos y los fitoparásitos, coincidiendo con otras experiencias anteriores.

At the time of the extraction and preparation of the samples, the Baermann method (1917) and the lactophenol-glycerin mounting method (Siddiqi, 1964) were used. When analyzing the samples, the soil maturity index (Bongers, 1990) was calculated from the analysis of the relative abundance, both from the taxonomic point of view and the trophic point of view. 36 genera and 41 species have been found, obtaining that the dominant order is that of the rhabditids, composed mainly of the infraorders Cephalobomorpha and Tylenchomorpha. As for the dominant trophic groups, they are bacteriophages and phytoparasites, coinciding with other previous experiences.
