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 does feed EC change during one irrigation event?
Sample the beginning, middle and end to distinguish timing effects from an unstable recipe.

Why the root zone matters
Short events can deliver a changing mixture into cocopeat even when the average tank EC looks right.
01 / OBSERVE
Three checks before you change anything
- Record injection start and stop times relative to the zone valve.
- Collect separate emitter samples across the event.
- Check line volume, mixing delay and any water-only tail in the programme.
02 / NARROW IT DOWN
When does EC change?
Choose the closest observation for a suggested next check.
Low at the beginning
Review transit delay and the proportion of the event that delivers the intended feed.
Low at the end
Check whether a programmed water-only tail is intentional and appropriate.
Irregular throughout
Inspect injector operation and supply stability before adjusting crop targets.
03 / TAKE THE NEXT STEP
Leave with something useful
Show the event profile to the irrigation operator and nutrient adviser.
Keep in mind
Do not use one mid-event sample to describe a highly variable complete pulse.
