      abstract     = {Electromagnetic induction (EMI) data are often used to
                      investigate spatial and temporal patterns of soil texture,
                      soil water content and soil salinity. We hypothesized that
                      the EMI methodology might thus also offer potential to
                      detect agricultural legacy effects originating from
                      fertilizer application and irrigation of different fields.
                      Therefore, we performed EMI measurements on two long‐term
                      field experiments (LTFE) at Thyrow near Berlin (Germany)
                      that differed in agricultural management with regard to
                      long‐term irrigation in combination with mineral (NPK and
                      lime) and organic amendments (straw and farmyard manure).
                      Two different rigid‐boom multi‐coil EMI instruments were
                      used to measure simultaneously the apparent electrical
                      conductivity (ECa) over nine different depth ranges to study
                      the entire soil profile from topsoil to deep subsoil.
                      Additionally, soil samples were taken from the different
                      treatments to ground‐truth the measurements and
                      disentangle the nutrient application or irrigation effects
                      from natural soil heterogeneity. The soil samples indicated
                      a rather homogenous soil and the correlation between soil
                      parameters or states were not significant. However, the
                      treatments showed significant differences in measured ECa
                      values. In general, ECa values were largest on regularly
                      irrigated as well as on mineral and organic fertilized
                      plots, with regular irrigation exhibiting the largest impact
                      on EMI records even though the last application was months
                      before the EMI measurement. Overall, this study reveals that
                      EMI data can support the classical in situ assessment of
                      agricultural management effects within LTFE, while offering
                      new potentials in detecting and understanding legacy effects
                      of agricultural management on spatial soil properties at
                      farm level.},
