Abstract


This work aims to study precision agriculture, looking for low-cost alternatives. Due to the great environmental impacts that improper handling causes to the soil, the definition of areas of production using tools such as electrical conductivity sensors of the soilhelps to perform a faster soil type analysis and assist in the decision to be taken for soil correction. For the determination of strength and electrical soil capacitance,it was used the Octopus Soil Humidity sensor modified with digital and analog multimeters. From the readings, correlations were made with soil attributes (sand, silt, clay). The results were satisfactory mainly with the use of the analog multimeter, which showed a strong correlation of the electric resistance reading with soil attributes, as sand and clay.
