Ok I'm back. Once you get your P and K out there is really no need to put out much N the first year. You will get a little N with the other nutrients. Now the most important part, micronutrients. Your new tree will grow best if it gets monthly applications of zinc, nickel, and boron. These should be applied to the foliage. Also put down a heavy mulch 8' diameter around tree thes keeps form drying out, adds nutrients and keeps weeds from competing with tree.
Once you get good growth on your new shoots break off all but the best two. Allow these to grow training the best for your main trunk leave the other to feed tree but cut off at 1" diameter. If all goes well that will be its first winter.
All you Texas guys and gals should look into the pecan short corse put on at Texas A&M. I have been and it was well worth the time.
