Tree and Shrub Soil Test Calculator

Directions: This interactive calculator is intended as an exploratory tool to help you interpret your soil test results for a single soil sample.  Calculations are based on a generalized model of soil variable for Alaska soils. The yellow highlighted boxes labeled "Enter Your Values Here" are available for you to enter information. This calculator will only make calculations for the data you have entered.  You will need to double click in the box to activate the spreadsheet so that you can enter data. There are many variables listed that you may enter.  Depending on the soil test you have obtained, you may not have data to enter in every box.
