What is the N-P-K and micro nutrient analysis?

I don’t know the chemical analysis of these tree spikes. I do know that they grow my many trees fast and healthy. I am about to put them down now for this year. I trust these tree spikes to grow my trees fast and sturdy.

Can i use it for fruit tree?

The Jobe's 1611 Evergreen out door spikes are just used for evergreen's in the fall. There is a Jobe's fertilizer spike just for fruit or regular trees.

I have trees 1-2 inch trunck diameter. I did not see 30' requirement. I placed 2 spikes for each tree , 6 inch from trunck. Will this burn my trees

Well first off it's 30" not 30', but it may very well burn them putting them that close. If you just did this I would dig out the spikes and either place new ones at 30" or try to reuse the old ones. These are a great product and I have used them for many years. Stay with it but please watch the placement.

What is the ideal depth to plant the spikes?

not necessary to go very deep, but that is only an uneducated opinion...I use a root auger and go down about 12", and place the fertilizer spike in, and then cover it over with soil; it seems to help, especially my shrubs
