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.

How do mS/cm and µS/cm compare on an EC report?
Check the unit before concluding that two conductivity results disagree.

Why the root zone matters
The same coir extract can be reported on different numerical scales without being a different solution.
01 / OBSERVE
Three checks before you change anything
- Read the complete unit beside each result rather than copying only the number.
- Recognise that 1 mS/cm equals 1,000 µS/cm.
- Keep the extraction method and sample identity unchanged when making the unit comparison.
02 / NARROW IT DOWN
What is different?
Choose the closest observation for a suggested next check.
Only the EC unit
Convert the unit explicitly and retain the original reported value.
The extraction method also differs
Resolve the method difference separately; unit conversion does not make different extracts equivalent.
The report says ppm
Check whether it is a calculated meter scale or a laboratory concentration result.
03 / TAKE THE NEXT STEP
Leave with something useful
Write units into every spreadsheet column used for crop monitoring.
Keep in mind
Do not treat a unit conversion as a conversion between extraction ratios.
