On-the-go measurement of soil parameters in field-scale, which managed in a determinate farming and fertilizing mode, was carried out using soil moisture content (MC), electrical conductivity (EC) and mechanical resistance (MR) measuring system and EM38. The correlativity among the soil parameters was investigated based on the soil parameter spatial distribution. The results showed that the combined sensor could response the field MC and EC variation. Soil EC in field scale could be predicted by soil MC, MR and fertilizing information. 
