The present work tried to identify plants indicating soil attributes in cropping systems of Ilex paraguariensis and Mimosa escabrella in the town of Augusto Pestana, Northwest of the State of Rio Grande do Sul, Brazil. The cropping systems were: I. paraguariensis associated with M. escabrella; I.paraguariensis in slope area; I.paraguariensis in low area and M. scabella in single cultivation. Five plants samples (1 m²) and soil samples were collected in the cultivation line, each one composed of five sub-samples. The spontaneous plants of each system were recensed with relationship to the diversity and abundance and correlated to the soil fertilityconditions. The species of great adaptive capacity in various soil and environment conditions are considered Hypsissuaveolens, Loliummultiflorum, Vicia sativa and the Poaceae family, since they colonized all cultivation systems. Adiantopsissp. was only not present in the system of Ilex paraguariensis intercropped with Mimosa scabrella, considering the most significant occurrence species, with more than 5% of individuals. Cyperus sp., Aristidalongiseta and Iresinediffusa are considered indicative species of low pH.
