Soil macroinvertebrates mediate key soil processes, but field evidence is scarce in coastal Neotropical pastures. This study evaluated how soil physicochemical properties covary with macroinvertebrate abundance and diversity in tropical pastures of Manabí, Ecuador. Thirty-five cattle farms, seven per locality, were sampled by convenience between April and July 2022. Eleven physicochemical variables (0–20 cm) and macroinvertebrates from four 50×50 cm monoliths per farm (30 cm depth) were analyzed at taxonomic group level. Diversity indices and principal component analysis were applied. Of 19,358 individuals in seven groups, Oligochaeta reached 64.20% of abundance, with a mean density of 553 individuals m-2. Cation exchange capacity and clay content contributed most to physicochemical variation; diversity was lowest where physical conditions were most restrictive. Although the measured properties were adequate for pasture production, macroinvertebrate density was less than half the worldwide reference, indicating that physicochemical characterization alone did not capture soil biological condition.

Los macroinvertebrados del suelo median procesos edáficos clave, pero la evidencia de campo es escasa en las pasturas neotropicales costeras. Este estudio evaluó cómo las propiedades fisicoquímicas covarían con la abundancia y la diversidad de macroinvertebrados en pasturas tropicales de Manabí, Ecuador. Se muestrearon por conveniencia 35 fincas ganaderas, siete por localidad, entre abril y julio de 2022. Se analizaron once variables fisicoquímicas (0–20 cm) y los macroinvertebrados de cuatro monolitos de 50×50 cm por finca (30 cm de profundidad), a nivel de grandes grupos taxonómicos. Se aplicaron índices de diversidad y análisis de componentes principales. De 19.358 individuos en siete grupos, Oligochaeta alcanzó el 64,20% de la abundancia, con una densidad media de 553 individuos m-2. La capacidad de intercambio catiónico y la arcilla aportaron más a la variación fisicoquímica; la diversidad fue menor donde las condiciones físicas fueron más restrictivas. Aunque las propiedades medidas resultaron adecuadas para la producción de pasturas, la densidad de macroinvertebrados fue menos de la mitad de la referencia mundial, lo que indica que la caracterización fisicoquímica por sí sola no captó la condición biológica del suelo.
