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.

What should I check when changing irrigation water sources?
Treat a source change as a change to the nutrient programme as well as the water supply.

Why the root zone matters
Different dissolved ions and alkalinity can alter the solution supplied to cocopeat.
01 / OBSERVE
Three checks before you change anything
- Obtain suitable water analyses for both sources.
- Review nutrient contributions and treatment requirements with the adviser.
- Monitor delivered feed and crop response after the transition.
02 / NARROW IT DOWN
What changed?
Choose the closest observation for a suggested next check.
Emergency alternative source
Test promptly and agree a temporary management plan before prolonged use.
Planned seasonal switch
Prepare the revised recipe and equipment checks before switching.
Blended sources
Measure the actual blend and document its proportions and variability.
03 / TAKE THE NEXT STEP
Leave with something useful
Keep source identity in the irrigation log for every period.
Keep in mind
Do not assume equal EC means two water sources contain the same ions.
