It did — the soil around our hydrangea , which we ’ve ameliorate to a great extent , tested at 6 on the pH scale of measurement , while the soil around our daisy register at 6.8 . Both seemed accurate base on our diachronic knowledge of our soil and the amendments we ’ve made .

We then tested both wet and clean levels in various garden spots , and the Atree again seemed precise . While this tester did n’t ascertain things like specific nutrient level , we found that it would be great for nurseryman who are happy with the health of their ground but would like to know if the light is adequate or whether the soil is drain well .
