Presented at the 1st International Electronic Conference on Agronomy, 3–17 May 2021The intensification of agriculture has greatly enhanced crop productivity, but also its
potential environmental impact. Nutrient recycling and an increase in resource use efficiency are the
key points to keep production at high levels with minimum impact. The present work’s goal was to
provide new insight on the spatial variability of soil chemical properties in a vineyard. For this, three
different zones were identified in a 6.77 ha parcel, according to the remote sensing of apparent soil
electrical conductivity (ECap) and the normalized difference vegetation index (NDVI). Soil samples
from specific locations were then collected and chemically described, and the resulting data were
statistically analyzed. ECap and NDVI appeared to be efficient tools to define different zones within
the vineyard, with most of the soil chemical properties varying at the highest significance level
(p < 0.001) according to the F test, except for extractable phosphorus (Égner-Rhiem) and organic
carbon (TOC method). Overall, our results revealed potential for the implementation of site-specific
soil fertilization and soil quality managementinfo:eu-repo/semantics/publishedVersio
