The variability of soil properties in space and time is a challenge to their measurement. Currently, apparent electrical conductivity (ECa) of the soil profile can be used to estimate indirectly the spatial variability of the soil properties: salinity, texture, cation-exchange capacity and moisture content. An electromagnetic induction sensor does not require direct contact with the ground, and data collection is relatively easy, rapid, and inexpensive. This allows a larger number ofdoi:10.5281/zenodo.891094 fatcat:syayztr6onbvbejoc7rxjsyduy
