Thanks for the link...
it sounds as though they have the capability to measure how much P is in a given soil, but chose to report only the relevant amount that is expected to be plant available...

Annual crops have very little chance of acquiring AMFungi in their root systems in order to mine the unavailable P in the same way that lawns are able to do, so their concept of High/Low P in the testing process is skewed from that angle right off the bat...
i.e. what may be Low for corn, will be more than adequate for turf,,, and this article appeared to consider corn and soybeans...

IMO,,, turf managers would be further ahead in promoting the soil health and beneficial Fungi than dumping on ferts that are recommended for 240 bushels/A of corn... I still say that grass is the easiest thing in the world to grow, in that it does so well b4 we start meddling to make it better...
