Water tests
Read your Wallace Labs water results, compare nutrient ratios and see what your source water contributes to a liquid feed.
This page describes your water.
It does not calculate amendments or a feed recipe.
Open your water test
Open a Wallace Labs PDF or spreadsheet.
You can also open a supported water summary, or enter results by hand.
Your files stay on your device.
PDF, Excel, OpenDocument, CSV or TSV, up to 10 MB.
PDFs need selectable text.
Scanned or unrecognized reports can be entered by hand.
Keep results such as <0.02 exactly as printed.
No water test opened.
Review your water results
Check each value, qualifier and unit against your original report.
The original reading stays visible beside your edits.
Empty or unresolved results will not be treated as zero.
This summary does not print concentration units.
Check the original lab report before confirming them.
Electrical conductivity needs its own unit.

Water readout
Water nutrient ratios
Ratios use elemental mass concentrations in mg/L.
They describe the water you tested, rather than a target to pursue.
These are not soil-test ratios, molar ratios or the sodium adsorption ratio (SAR).
| Ratio | Test results (mg/L) | Water ratio | Reading notes |

Already in your water
Choose the water volume for your batch.
These amounts come from the water before you add any feed products.
Each row keeps its reported chemical basis, such as nitrate as N or sulfate.

All reported results
Less-than and greater-than results remain limits.
ND means not detected, not a measured zero.
Missing measurements stay uncalculated.
