It would be great to get much more soil info besides drainage -- like nitrogen, phosphorus and potassium content -- to see if we are using the proper fertilizer for a plant. For example, my bougainvillea has tremendous foliage and no flowers. So I plug in EasyBloom to see if the soil is ok, and all I get is drainage info on the soil. My guess is that the soil is nitrogen-rich, but I may never know.....
