I had a soil test run this year and have found out that the pottasium and phosphorous levels are labeled "excessive" on my soil test. I should no better than to put down an NPK fertilizer without running a soil test first which I've been doing for a while now. Consequently I've been on the search for Urea or Ammonium Nitrate so I can just put down nitrogen for the next 3 years until it's time for the next soil test (per soil test recommendation) I didn't realize how difficult this is to find I'm sure as a result of all this misuse and destruction that has been casused by nitrogen fertilizers in the past. I work at a garden center so I might be able to get a couple of bags order through one of our distributors, but befoe I go through the trouble does anyone know where this fertilzer can still be purchaed?
