How does the Veris method of rolling electrodes compare to electromagnetic induction methods of measuring EC?
Although these two systems use different methods of measuring soil electrical conductivity (electromagnetic induction vs. direct contact), research has established that measurements by the two devices are strongly correlated to each other, when operated in a controlled, research setting. When soil EC mapping is conducted in field-scale commercial agriculture, the advantages of the Veris system are numerous: Simple and Easy to Use: The Veris EC Systems were designed expressly for mobilized mapping of farm fields. The implement is ruggedly constructed of tubular steel and the spring-loaded coulter-electrodes can take the punishment of tough field condition. Direct contact measurements of soil EC are not plagued with interference from nearby metal, utility wires, or engine noise, as is the case with the electromagnetic induction method. Because the position of the electrodes and the current are pre-programmed, with Veris there is no need to calibrate or null any of the settings. The instr
