That has been talked about a lot in recent years and what I find most interesting about the subject is that most plants require help from biologicals, in a symbiotic relationship,, in order to extract the P from the soil...

Since the quicker that relationship is formed, the better... I don't believe that using "starter fert" (with P) is a good idea in the long term...
Young plants are in need of AM Fungi at birth and the application of P causes a noticeable reduction in AM Fungal activity, so we're actually working against the natural life cycle of the plant...

Then of course there are those who believe that a P application actually enhances germination...

Yes, there are lots of interesting things to learn...
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
