Open Source Logan Labs Calculator:
BuildASoil Soil Test Calculator Version 1.5.5
Read the instructions for enabling Macros or this file will NOT work.
Over the years we have created a spreadsheet for interpreting your soil tests from Logan Labs.
This is an excel spreadsheet that uses Macros to look up data from tables and apply formulas and create a final report.
We are in the process of upgrading this to a web app that will allow for adding other products in the report section and will allow for easier use from the Logan Labs PDF but until then, I feel if you are handy with Excel you should have access to this free tool.
The Yellow fields are open for you to input your data and if you want to edit anything else you will need to unlock the sheet using password: 777
First Step: ENABLE MACROS
Excel has stepped up security on Macro enabled sheets and has removed the "enable" button. This file is safe and secure but we do not have it digitally signed so it will display as a security risk because Microsoft has no idea who BuildASoil is. Instead of getting a digital security certificate we are going to move this to a webapp to ensure it improves with time.
