Hi Stephanie
Thanks for writing and in your place, I would continue to compost. A problem with such soil tests is how they ignore so much of what makes plants grow – biology! And I am not convinced they present the whole picture of what is available, and when.
All your soil fauna and microbes are loving your compost and hence your good results.
For anyone else reading this, I urge caution in taking advice from soil tests. I had one (a free offer) done that said my soil fungi were low, yet growth was amazing, literally.
