Increasing evidence suggests that plant invasions are promoted by altered plant-soil interactions. However, we still lack studies exploring differences in the effects of invasive and native species on soil properties, and particularly studies that control for species phylogeny and abundance. Here, we grew seven congeneric pairs of invasive and native species with comparable cover in the studied region in a 12-week common garden experiment. We analyzed the nutrient levels, pH, and composition and abundance of microbial communities in conspecific-conditioned and unconditioned control soil. Then we used ratios of the soil properties in conditioned and control soil to express species effects on the soil. Our findings reveal that invasive species used more phosphorus from the soil and supported mycorrhizal communities with a higher potential to colonize plant roots than native species but these abilities are also dependent on genera. We further observed strong differences among plant genera in many soil properties, and genera from the same families tended to have similar effects on the soil. Furthermore, we found many interactions of genera and invasion status. Effects of plants on the soil were also determined by plant biomass production, independent of species identity. The results suggest that invasive and native species differ only in a few general effects on the soil, and the differences are largely genus specific. They also indicated that species phylogenetic relatedness and individual plant biomass should be considered in future studies on the effect of plants on the soil.
