In furrow “pop-up” fert

Asked March 6, 2020, 1:36 PM EST

Is in furrow fert better under, on top of the seed, or dibbled on the ground? Does P2O5 move enough in the spring to reach a germinating seed of it is 2” above on top by dibbling on furrow? How hot is to hot phos/N in furrow on seed? Can I run higher rates as a dribble and still benefit ROI of fert?
