Soil Amendment Recommendations Using OrganiCalc – We provide you with a set of certified organic amendment recommendations designed to balance the mineral content of your soil along with written comments on the soil.  The recommendations are based on your Logan Labs standard Mehlich 3 or AA8.2 soil test and are aimed at providing a generous, balanced soil reserve of all plant-essential elements. Here is a sample report.

How does it work? Our order form asks you a series of questions which let us know what, how and where you are growing. As part of the order process, you upload your soil test report. We do a personalized analysis, then email you an OrganiCalc report with comments.

How long does it take? It usually takes 3 to 5 working days from the time we receive your test report before you receive your amendment recommendations.
