Soil electromagnetic conductivity may give information regarding soil drainage, salt composition, nutrient density, and texture. High electrical conductivity correlates to high cation exchange capacity, and is often found in drier soils (due to less salt leaching) or clay soils. Electromagnetic conductivity soil mapping was conducted on different vineyard blocks, and Cabernet Franc blocks of low and high conductivity were harvested separately but on the same day and processed identically. There were no chemical differences between wines, and sensory results were not significant. However, the trace metal content of the wines were different.
