I have done testing on liquid Phosphorus movement in a band placed on top of the soil. After 2 weeks at 2.5" depth with 1.5" of rain the P level at that level was up 200%. I encourage you to pull some 2 to 2.5" tests then after planting and a 1 to 1.5" rains pull the 2 to 2.5" in test under the band your planter applied.
