One of the basic practices of precision agriculture is the requirement to define spatial variability in soil properties within an agricultural field to make decisions that can maximize profitability and reduce negative environmental impacts. Various on-the-go soil sensors have been developed over the years. In this study, an integrated soil mapping system (ISMS) was constructed to combine a capacitance-based soil moisture sensor, an optical sensor detecting differences in soil organic matter content, and a load sensor focused on shallow soil mechanical resistance. Measurements obtained using ISMS were compared to gravimetric and volumetric water content, organic matter content and cone penetrometer measurements through a series of laboratory and field tests.
