Congratulation on your 5 acre farm. I am sure you'll do great there.
yes, my approach is different. it is more about getting in tune with what is needed and the reality around us. this thinking and method started evolving while reading Graeme Sait's Nutrition Rules ebook. this led me to Albrecht's work on nutrition, then "Weeds Guardians of The Soil" and on to "Conquest of the Land Through Seven Thousand Years". All of these provided new insights.
It is amazing how wrong I use to think about pests, weeds, and the soil. I can't imagine how hard it is for a conventional long term farmer to come to grips with this new perspective and like I think differently.
I am trying a few new things in my gardens this year, specifically I have finely chopped leaves and cultivated them in for carbon. I am using a little more potash, direct from my fireplace. I wanted to try recycling some drywall (Gypsum) for the Calcium in it, but decided to try it first in the front yard on the grass after cutting aeration trenches with one of my Mantis tillers.
I have another area, next to a retention pond that I want to plant with some Ground Cherries, but before I do that I am going to early plant weeds there that I bought some seeds from another member, then cut them down before they seed and cultivate them back in as "Green Manure".
Another test this year will be using a (20:1) foilar spray on one garden that will be pasteurized urine (Urea). Read several reports that proved the value, plus USDA & EPA are both sponsoring many tests.
After almost a year, I was approved for Agriculture Research (ARS) to try and grow Brosimum Alicastrum in colder climates and also to breed it. This is pretty exciting to me.

I would also suggest that you either watch or download Lorraine Johnson's talk at the NANPS. It is really terrific.
As to your fruit trees, you might want to get some of the grafted apples (2,3 or 4 species on one tree) which cuts the latency of production from 5 years to under 2 in most cases. And they are not that expensive- under $100 typically per tree.
