I agree with Christopher and Sheri. The reading of ph would be a marvelous addition. I have blueberries which need an acidic condition but I need to know the effects of their drain off in order to choose plants to place around them. The soil tester Christopher uses is a good idea but is bother. I can take "testings" to my extension agent who will send them for soil readings. How often should I do that? and from how many areas around the "homestead"?
