Spray system for nutrients

Looking for ideas from this experienced group on how you do micro spray irrigation on a small orchard. The land (0.6 acres) is sloped where the highest spot is near the Jujube and the lowest is by the Hazel Nuts.
I am looking at around 144 trees and have around half planted now. I have covered the whole area with 12 inches of wood chips.
The water well (in the shed) is rather large and the soil is naturally damp clay, so watering will only happen late fall during short droughts.
I would like to use micro sprayers or similar above ground spray type system that can irrigate the trees at 10 ft spacing and 15 foot between rows.
The goal is to use the irrigation system to put nutrients into the soil in early spring and late fall.
Thanks for your help.

I can't help you with micro spray irrigation.

Will you be using compost tea for your nutrients?

Here are a couple of threads that might be of interest:

I already put down Compost on top and then wood chips.  Need to find a easier way because of health and JADAM does seem to be easier.  
I was thinking of using a JADAM method called JADAM Microorganism Solution (JMS).  I think it is also caled IMO (IMS Indigent MicroOrganism).
Someone suggested to me to keep the nutrient fertigation separate from regular irrigation.  I have already put out a drip irrigation and it will not need to be used very often.
That I can run off a regular solar well set up.  Still need to find a way to do a separate fertigation system.  Looking at placing spigots around the 0.6 acres and using a garden hose to reach each tree.
