The aim of this study was to investigate the possibility of predicting CaCO3 content through Electromagnetic conductivity (EM) on cultivated soils. Soils were sampled at 30 locations within the study area. The EM was measured using a mobile electromagnetic induction (EM38) sensor. Relations between CaCO3 and EM were analyzed with linear regression and geostatistical analysis. Further research is needed to fully evaluate the potential of EM measurements for predicting CaCO3 in tilled soil. The results also show a strong correlation between EM, and CaCO3% (R2 > 0.9). The Wilcoxon test shows a non-significant difference between measured CaCO3 and those predicted by ECa (p > 0.05). This result confirms the EMI technique as a useful tool to evaluate the spatial variability of soil CaCO3. All of these results suggest that the EM represents a real possibility for reducing the number of soil samplings, by guaranteeing the reliability of the estimates of real values of CaCO3 and their surface spatial distribution. ECa could therefore be a useful tool to spatialize and predict the distribution of CaCO3 in soil cultivated.
