  abstract = {{E}lectromagnetic induction ({EMI}) is a non-invasive geophysical technique for studying the physical and chemical features of soil distribution. {T}his paper focuses on the relations of the apparent electrical conductivity ({EC}a) of soil, measured using a {P}rofiler {GSSI} {EMP}-400, with soil abiotic and biotic parameters: volumetric water content, p{H}, electrical conductivity, coarse elements, density and biomass of different earthworm ecological categories (anecics and endogeics).{T}rials were carried out in nine commercial vineyards in {L}anguedoc-{R}oussillon ({F}rance) cultivated according to different soil management technologies: grass cover, chemical weeding and tillage. {H}and sorting and a mustard method were used to measure the earthworms. {S}trong relationships between the abundance and biomass of anecic and endogeic earthworms and {EC}a values were found, particularly in grass covered and chemically weeded plots. {T}his result is supported by the high determination coefficients found ({R}-2 from 0.53 to 0.94). {O}ur results suggest that the {EMI} signal, as an integrated value of the physical-chemical conditions of soil, represents a real possibility for reducing the number of laborious earthworm samplings, by guaranteeing the reliability of the estimates of mean real values of earthworm parameters and their surface spatial distribution. {EMI} could therefore be a useful tool to spatialize and to predict the presence of earthworms in fields in perennial crops.},
