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   the knowledge of spatial variability of soil attributes is one important aspect to be known.  Researchers have concluded that ECa is a powerful for spatial heterogeneity characterization of several physico-chemical properties, identify edaphic and anthropogenic factors that may influence crop yield, and provides a viable approach for delineating areas that...
