Monitoring Nutrients and Salt

Water trapped in the detector can be sucked out with a syringe via the flexible green tube and monitored for its electrical conductivity or nutrient concentration. Samples should be taken immediately after irrigation. Note that the detector retains a small sample of water after self-emptying. before water is sucked out of the funnel by the drying soil. After self-emptying, the detector retains a small sample of water. This should be removed prior to irrigations from which samples for nutrient analysis are required.
