mini sunken hugle border ? adding nutrients

I want to dig a trench in a dry area along the driveway and put composted ramial chips (Composted and turned for a year ) , and garden compost in under the top soil ( to act as a water sink / wicking material )
I do not use fertilizer in the garden because I have used a lot of compost and things seem to grow well . but I am thinking this layer should have some thing to up the nitrogen , would a sprinkle of bone meal or urea be good or a balanced fertilizer ? I plan to put in a ground cover of some sort possibly strawberry , and inter plant with some perennials

It would add some. It will increase the decomposition rate of the wood and keep the wood from absorbing nitrogen that your other plants will need. Or plant some legumes to help.

Thank you that is an idea it will be a boarder along the driveway . I will look and see if sweet pea is a nitrogen fixer

Sweet pea will fix nitrogen but make sure you inoculate it with nitrogen fixing bacteria.

Thank you ,
