Indicator plants of soil attributes in cropping systems of ilex paraguariensis a. st.-hil. and mimosa scabrella in Southern Brazil
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.
