Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Why should I measure feed EC at the dripper?
The mixing tank result does not always represent what reaches the plant.

Why the root zone matters
Coir roots respond to the delivered solution, including any changes along the irrigation system.
01 / OBSERVE
Three checks before you change anything
- Compare source water, mixed feed and emitter samples using the same calibrated meter.
- Sample after the line reaches normal operation and record the collection timing.
- Check for old solution, overlapping zones or unintended water-only delivery.
02 / NARROW IT DOWN
Where does the difference appear?
Choose the closest observation for a suggested next check.
Tank and emitter differ
Trace the delivery path and repeat sampling at intermediate points.
Only first discharge differs
Measure the start-up contribution and review line carryover.
All samples match
Use the delivered result as the input reference when investigating the root zone.
03 / TAKE THE NEXT STEP
Leave with something useful
Label every sample by location and event time.
Keep in mind
Do not compare a first-flush sample with a fully mixed tank sample as though timing were identical.
