From what i understand, P is necessary for seedling development, but the challange is that its not very mobile. I recommend applying it after aeration so it physically is deeper in the ground and is accessible to the roots. Or if it is a bare area, roto-tilling it in. otherwise, ive read it could take weeks to months just to move a couple inches into the soil.
