Time for some Soil Sampling?

When's the last time you've had your soil sampled?  Wondering about what PH your soil may have?  Does it have a useful level of phosphorous, potassium or mangenese?  Are you just blindly adding you chemical and time release fertilizers blindly hoping everything is in balance?  There is an easy wasy to deasl with this.
Hurry down to youir local Extension Service Office  with your $14 fee and get your soil sample The report you get back will look like this:

Looking at the report you can see the PH is 6.0   Maybe a bit on the acidic side.    Your member book I believe suggests a PH of 6.7 or so.  Even though the recommendation says add lime, that seems like heresy in our soils.  Knowing you garden, the culprit could be a heavy dose of Sul-Po-Mag .   Given that may be the case, then the question becomes how to add the Potassium without further acidifying the PH level.    Hummmm...      We'll have copies of the report at our meeting.  Also, we'll have some soil sample bags for you.

Hopefully one of our Consulting Rosarians can shed some light.
