Precision soil moisture, fertiliser solute concentration—and frequently—salinity management at replanting, is essential in the quest to produce a healthy root system.
Australian company Sentek Technologies, designs and manufactures precision, profiling EnviroSCAN probes that provide near continuous measurements of these parameters.
As the roots develop, the irrigation cycle can be managed accordingly.
Importantly, a well-positioned probe can, with experience, assist in building and maintaining a ‘wetting onion’ when pulsing.
TriSCAN sensor information, which includes solute concentration, especially when used in conjunction with the Sentek SoluSAMPLER, can enhance the efficiency of fertigation.
In summary, graphical interpretation of the information using Sentek’s EnviroSCAN and/or TriSCAN, allows tracking of root development; answers when and how much irrigation to apply; tracks fertiliser usage and salinity build-up.
