FAQ’s

I have a soil test report from XYZ Lab, not Logan Labs. Can I use OrganiCalc with it?

Lab tests are not all the same. Other labs use different testing methodologies, even if they do a Mehlich 3 or AA test. OrganiCalc only works with Logan Labs soil tests. There is also a converter for Spectrum Analytic soil test reports.

You can order Logan Labs soil tests on our website, here.

I have a soil test and a saturated paste test report from Logan Labs. Can I use OrganiCalc with it?

Yes, OrganiCalc Pro version 8 now supports analysis of a saturated paste test report alongside your Logan Labs soil test report.

When should I not use OrganiCalc?

For Pastures

These recommendations are for growing nutrient dense food, not for pasture. Aside from the expense of bringing large areas up to these high nutrient levels, herbivores are very sensitive to changes in taste. Mineral application limits are much lower for pastures. Consult an analyst experienced in pasture management. Contact Erica@GrowAbundant.com, and we will share what we have learned about pasture management.

Your soil is already balanced

Usually this happens after a few years of soil mineralization. Your soil settles to a point where the plants are growing very well. You don’t want to disturb this equilibrium, or lose valuable (cation) nutrients. You want to add only enough of the anion nutrients to grow a good crop: nitrogen, sulfate-sulfur, boron and molybdenum.

When your soil is mineral-balanced, it’s time to really focus on the biology.  5% organic matter is a nice number where summer is hot; 8 to 9 % is a good number where summers are coolish, such as in the Maritime northwest. Organic matter over 30% is more than enough.

Finally, if your soil is otherwise balanced and you have excess Ca, don’t try to fix it; leave it alone.

Can I use OrganiCalc for something besides vegetables?

Yes. Both OrganiCalc Pro and OrganiCalc for Gardens allow you to choose from a list of common crops. OrganiCalc Pro allows you to adjust all of the mineral targets in order to tailor the report for any crop.

I have a bag of XYZ amendment. Can I use it?

OrganiCalc Pro allows you to change the list of amendments it selects from, and remembers the changes until the form is reset.  Alternatively you can use this form to convert a single amendment.

*Note that OrganiCalc is designed to prevent excesses of any nutrient in the soil and will not recommend an amendment containing a element that is already sufficient in the soil. So if your bag of XYZ contains magnesium and your soil already has sufficient magnesium, OrganiCalc will not recommend it.

Can I use compost along with my OrganiCalc recommended amendments?

Yes, but it’s good to have an idea of how many nutrients are being supplied by the compost. This page helps explain how much compost to use.
