Does anyone know how to test the pH of your soil (more acurately than just with litmus paper)... I have a nice pH meter that I use for photography, so if I use a buffer sol'n, and then test the pH against water, and then use water to disolve some of the soil? Should i let the soil mix with water for a while. How much soil to how much water.. Or Better ideas... I think a lot of my issues with the garden stem from soil acidity due to huge ass pine trees. So yeah! :) Any thoughts?
