Open source soil test interpretation

Drop in your Logan Labs report and get an amendment plan

Works on any Logan Labs report, whatever your soil is and however long you have been running it. Full test and you get an amendment plan with real rates. Saturated paste on its own and you get a mid round read on what the plants are drinking and what to change in the feed. Free, no account, and your files never leave your browser.

Step 1. Add your reports

If you ordered the BuildASoil Complete test, your Mehlich 3 and your AA 8.2 arrive on the same PDF, side by side. Drop that one file in the first box and leave the second alone. If your AA 8.2 came separately, use the second box.

Only have a saturated paste? Drop it in the third box on its own. Plenty of growers pull one mid round to see what the plants are drinking today, and that is a fair question to ask by itself. You get the paste scored and feeding guidance rather than an amendment plan, since mid round there is nothing to mix in anyway. If your report carries several beds, all of them get compared side by side.

Your Mehlich 3, with the AA 8.2 alongside it if they came together.
Waiting
AA 8.2 alone
Only if you ordered it after the fact and it came as its own PDF.
Not needed if it is on the first one
Saturated paste
What is dissolved right now. Works on its own for a mid round check.

Your last entry came back after the page reloaded. It is held in this browser tab only and disappears when you close the tab.

Step 2. Check the numbers

Every field here is editable, including the ones we filled in for you. If the parser misread a number, or your report says something different, type over it. Nothing is locked. A blank field is skipped rather than treated as a zero, so leave out anything your test did not measure.

read from your PDF the lab qualified it, like organic matter reported as over 20 you changed it you typed it, or left it blank

Did we read a number off your report wrong, or miss one entirely? Email support@buildasoil.com and we will fix it. Logan changes their layouts sometimes and we do not always hear about it.

That puts your numbers on the clipboard so you can paste them straight into the email. Delete anything you would rather not send.
