I have to object to the last sentence. I’ve gotten lots of soil tests from various locations in soil and greenhouse media where I need more nitrogen (almost always) and potassium (sometimes), but never phosphorus. And I even live in one of the blue states with lower P in the soil. https://pubs.usgs.gov/sir/2017/5118/sir20175118_element.php?... |
