Técnicas de medida de condutividade elétrica na agricultura de precisão

Abstract

Until recently, Precision Agriculture was thought of as an unviable tool for small and medium producers, as it believed that it was an expensive, inaccessible tool. However, with the advancement of technologies, it was possible to access simple and easy methodologies, comprising most of the parameters of soil analysis, tracing the spatial variability within the property, thus obtaining different soil managements for certain areas, as well as better use of inputs and optimization of agronomic practices, with what is called heterogeneity of agricultural parcels through homogeneous management zones. One of the suggested parameters for carrying out these mappings is the Electrical Conductivity of the Soil, a variable capable of correlating with the other attributes of the soil, such as humidity, productivity, topography and salinity, also presenting ease in measuring the data, an excellent alternative for the development of PA and more sustainable agronomic planning
