Abstract


This paper focuses on the search of low cost alternatives with precision agriculture application. Incorrect soil management causes expenses and damages to production. Thus, a more accurate soil analysis arises in order to study its features, such as soil salinity. The analysis was made by electrical conductivity sensors, in order to provide the correction to be applied. Soil electrical resistance measurements were given by a sensor consisting of copper plates and an insulating material, along with an adjustable power supply, a digital multimeter and an analog multimeter. Based on the measurements, correlations with soil chemical properties were performed.
