Increase in machinery size and its random traffic at fields cause soil compaction resulting in damage of soil structure and degradation of soil functions. Nowadays, rapid methods to detect soil compaction at fields are of high interest, especially proximal sensing methods such as electrical conductivity measurements.

Results of randomized block experiment showed a high significant difference (p <0.01) in EMI data measured between compacted and non-compacted areas.
