Garden Tool 

Test your soil for Ph and nutrients before your next planting project. Our county extension service no longer tests soil, but they do give information on how to take a soil sample and where to send it. Soil Sampling for Home Gardens and Small Acreages by Oregon State University Extension Service will get you started.

After you have your soil test analysis with its recommendations for 200 pounds of nitrogen per acre, use these handy conversion tables to convert that to your 100 square foot P-patch. Fifty other tables and formulas will help you convert just about anything you might need for the garden, including how much potting soil you will need to fill those 10" flower pots. Conversion Tables, Formulas and Suggested Guidelines for Horticultural Use from the Cooperative Extension Service, University of Georgia College of Agricultural and Environmental Sciences.
