[en] Among the crops production factors, the soil is obviously one of the most important.
Therefore, within the context of Precision Agriculture, the spatial variability
knowledge of its physical and chemical properties is essential as a decision support
information for cultural operations modulation.
The purpose of this study is to assess the capability of electromagnetic induction
sensing of apparent electrical conductivity (ECa) for the characterisation of withinfield
variability of soil physical and/or chemical properties in the particular soil
conditions encountered in our experimental area, namely non-saline deep silty soils.
ECa maps were produced on a 7ha field in April 2001, September 2001 and April
2002. Concurrently, an intensive soil survey (112 points) was carried out in
February 2001 in order to determine a series of physical, textural and chemical soil
parameters. ECa accurately described clay content, and exchangeable K and Ca
cations concentrations.
