Abstract
Soil biological functioning emerges from tightly coupled biochemical, electrochemical and transport processes, yet these dimensions are commonly assessed separately. This study evaluated whether redox potential, soil enzyme activities and spontaneous electrical spectral signatures provide convergent information for distinguishing contrasting management systems in a coffee farm located in the southeastern region of Brazil.
