Different types of proximal soil sensor are used in precision agriculture to map the apparent soil electrical conductivity (ECa) to identify the within field soil variability. Most of the work related to map soil properties in precision agriculture has been conducted in upland crops and not a single work is reported to map the soil properties in a paddy field. Therefore, the present study was conducted to check the potentiality of EM38 proximal soil sensor to map the key soil properties of a paddy field in the alluvial plain of Bangladesh. ECa was measured by EM38 in two measurement mode viz....
