Abstract: SUMMARYPotted Osteospermum hybrida plants grown in a greenhouse during the Winter were irrigated with water having electrical conductivities (EC) of 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5 or 5.0 dS m−1. The following relationships were studied in order to improve the management of saline irrigation systems using soil moisture and EC sensors: pore water EC (ECPW) using the pour-through method (ECPWPT) vs. ECPW estimated using a GS3 sensor (ECPWGS3); ECPWPT vs. bulk EC (ECB); ECPWPT vs. leachate EC (ECL); and ECPWGS3 vs. ECB. The tolerance of Osteos...
