I missed seeing this thread until today.
I am going to take it back to basics for a second or two. The type of soil and It's Chemical holding power should have a bearing on your selection of a Fertilizing program. Slow release liquid Fert is no good on sandy soil. It runs through before it can used and only pollutes the water table. Clay Soil it has a better chance of being used if it doesn't run off.
I am not going to bring out the SOIL SAMPLE Flag because I haven't pulled a soil sample in Years. But I know what my soil is and has or doesn't have that I need to add. I am sure my Fert program wouldn't work in other areas as good as it does in my area.
