Decagon Devices wireless sensor networks for irrigation management
Changes in the salinity (EC) of the pore water (EC pw; , thin line) in the growing medium (peat-pumice mixture) and of the nutrient solution (thick line) fed to pot ornamentals grown at CESPEVI (Pistoia) in the spring-summer of 2008. Two <t>irrigation</t> regimes differing for scheduling method and the source of raw water were compared: : 1) timer control with nutrient solution (EC = 0.80 dS m −1 ) prepared using low-salinity groundwater (EC = 0.50 dS m −1 ); 2) WET scheduling and two sources of water (groundwater or saline water with EC = 1.50 dS m −1 ) to prepare the nutrient solution with a maximum EC of 1.80 dS m −1 . In the latter, the nutrient solution EC was modulated by changing the rate of fertiliser addition and the water source in order to maintain the EC pw below 2.50 dS m −1 . In the lower graph, the bars close to the abscissa indicate the source of irrigation water: saline water (black), groundwater (white) or mixed water (grey).
