Do you just wet the leaves or do you drench the soil as well?

the 'farm' we would side dress 800 pounds of N per acre at the time of
hilling the potatoes. They received 600 pounds of 6-32-24 at planting.
I have found through research that the potato plant uses very little
food until about 55 days after planting. By that time most of the N is
washed out and the rest is now unsoluble.
