Testing and Calibrating the Hunter HPC-400 irrigation controller with Soil-Clik soil moisture module

Hunter HPC-400 irrigation controller with Soil-Clik soil moisture module will be used in two projects of remote-controlled automated irrigation with mulch for the production of specialty crops in Absaraka and Oakes, ND. This experiment is designed to determine the thresholds set in the control module to start irrigation at different soil moisture levels.

A Campbell Scientific CR1000 datalogger and a AM416 multiplexer are used to monitor and record the data of soil water potential, soil moisture and soil moisture in the above mentioned experiment.
