Soil test results are finally back. I don't think they look to bad. This is my first time doing soil testing. I never thought of taking care of a pasture can be broken down into a science. Looks like I'm low in P but everything else is fine. So what needs to be down to accommodate my P levels? Can this be purchased alone for a Tennessee farmers coop? Any grass masters thoughts will be greatly appreciated before I start throwing money at something I have no idea about. This is pasture land only btw.
