| description | Soil-inhabiting invertebrates play an important role in soil processes. Soil fauna include organisms of diverse sizes and adaptive strategies. Macrofauna, large organisms with body width greater than 2 mm, influence soil properties, both directly and indirectly. Their communities are influenced by soil management and thus, have a great potential as bioindicators. The objective of this study was to evaluate the effect of different crop-pasture rotations on soil macrofauna. Treatments included continuous agriculture without (S1) and with (S2) fertilization, 33% crop - 66% pasture rotation (S4), 50% croppasture rotation (S5), and 66% crop - 33% pasture rotation (S7). The number of organisms collected varied with land use intensity; treatments S1 and S4 had the lowest and highest population densities for most taxa, respectively. The Co-Inertia analysis between soil properties and population density was significant. The first axis ordered land uses in relation to its intensity. Oligochaeta and Coleoptera adults were associated with S4, the system with highest organic carbon and total nitrogen contents. The evaluation of soil macrofauna together with soil properties is a useful tool to assess land use sustainability |

The evaluation of soil macrofauna together with soil properties is a useful tool to assess land use sustainability Los invertebrados que habitan el suelo son actores importantes en los procesos edáficos. La fauna edáfica comprende a organismos con tamaños y estrategias adaptativas diferentes. Los de mayor tamaño, constituyen la macrofauna (ancho del cuerpo mayor a 2 mm), que se destaca porque directa o indirectamente afectan las propiedades del suelo. Las comunidades presentes son la consecuencia de las prácticas de manejo de suelo que se realizan, por lo que tienen gran potencial de uso como indicadores. Este trabajo tuvo como objetivo evaluar el efecto de diferentes sistemas de rotación cultivos-pasturas sobre las comunidades de la macrofauna del suelo. Los tratamientos evaluados fueron: agricultura continua sin (S1) y con fertilización (S2), rotación agricultura 33% - pradera 66% (S4), rotación agricultura 50% - pradera 50% (S5), y rotación agricultura 66% - pradera 33% (S7). El número de individuos varió de acuerdo a la intensidad de los usos del suelo evaluados. Los tratamientos S1 y S4 tuvieron respectivamente, las menores y mayores densidades poblacionales de la mayoría de los taxones. El análisis de Co-Inercia entre las propiedades edáficas y la densidad fue significativo. El primer eje ordenó los usos del suelo de acuerdo a su intensidad. Los taxones Oligochaeta y Coleoptera adultos estuvieron asociados a S4, sistema con mayor cantidad de carbono orgánico y nitrógeno total. La evaluación de la macrofauna del suelo conjuntamente con las propiedades del mismo, es una herramienta útil para evaluar la sustentabilidad ambiental de los distintos usos del suelo.
