Has anyone found one of these that is accurate? I wanted to get one of those prong type ones where you stick it in the dirt and it tells you the pH, water needs, sunlight exposure, and the N,P,K. They run about $20. But I was reading online last night and reviews weren''t so good. Said they don't work. They tried it in vinegar and cow's milk which is supposed to have a certain reading, and it wasn't even close.
I also got one of those capsule type tests yesterday. Didn't have much luck with that either. I got a reading for pH and the Phosphorous. Neutral and very low. The Nitrogen and Potash didn't even turn a color. So I tried another test. I had bought 2. One to do now and one for spring. Same result.
Anyone know where I can get a reliable test done for free or cheap? Does Lowes or nurseries do soil tests?
