This work was carried out to assess correlations between soil earthworm abundance and biomass and soil apparent electrical conductivity (ECa) measured by means of a Profiler GSSI EMP-400. The trial was performed in a 1-hectare commercial peach orchard characterized by a clay loam soil. Mustard method combined with hand-sorting technique were used to sample earthworms in areas (1 x 1 m) falling in cover cropped (CC) and chemically weeded (CW) strips. Statistically significant linear relationships were found between ECa, measured at 13 kHz, and earthworm biomasses in both CC and CW strips (R-2 > 0.72). Instead, abundance earthworm showed relations only in CW strips (R-2 > 0.50). EMI technique seems to be a very efficient tool to locate representative soil sampling areas and spatialize earthworm parameters at field level. specialized 076 068 Xiloyannis C. ed. edt IRD Inglese P. ed. edt IRD Montanaro G. ed. edt IRD 1084 479-484 Louvain ISHS 2015 International Peach Symposium, 8., Matera (ITA), 2013/06/17 1084 https://www.documentation.ird.fr/hor/fdi:010072212 10.17660/ActaHortic.2015.1084.66 9789462610798 [F B010072212] https://www.documentation.ird.fr/hor/fdi:010072212 https://www.documentation.ird.fr/intranet/publi/depot/2018-02-13/010072212.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-02-13 2018-05-16 fdi:010072212 fre
