1. Evaluation of DC-based Equipment for Apparent Soil Electrical Conductivity Measurement

Apparent soil electrical conductivity (ECa) is a soil parameter used for precision agriculture applications where knowledge of the spatial variability of soil attributes is an important aspect to know.  Researchers have concluded that ECa is powerful for spatial heterogeneity characterization of several physicochemical properties, identifying edaphic and anthropogenic factors that may influence crop yield, and provides a viable approach for delineating areas that behave similarly with respect...
