Create the Ideal Recipe for Your Soil

OrganiCalc is an online app available by annual subscription. Enter your Logan Labs soil test report and the area you want to amend. OrganiCalc produces a list of amendments to balance the mineral content of the soil and emails them to you.

The amendments are approved for use in certified organic production (check with your certifier).

OrganiCalc doesn’t recommend amendments that will cause mineral excesses in your soil. It is conservative by nature.

It creates an ideal mineral recipe for your unique soil.
