OrganiCalc is an online form that turns a Logan Labs soil test into a set of organic amendment recommendations. To use it you need:

  • A soil test report from Logan Labs, (not a saturated paste test report).
  • A subscription to OrganiCalc (you can get one here)
  • You need to be logged in. You can log in here.

Once you are logged in you will enter your test report into OrganiCalc. Once the form is full and if there are no typos or alerts, OrganiCalc creates a list of amendments.
