Re-imagining irrigated garden beds

I moved to a new farm which has several hundred feet of irrigated garden beds. However, it is on a northern slope (in zone 3) and the soil is pretty poor–loamy sand, and some I’d even call gravel. (Miss you, black gold of the plains) There is also a ton of quack grass, and it is shaded after 4/5pm by huge trees from neighbors to the west.

So…what do I do with this stuff? I’m considering a large plot of asparagus. I also am thinking to trail some peach trees, or other fruit trees. Maybe honeyberries.

I dont want to continue buying drip tape, but there is a lot to use up until it isn’t good anymore. Might as well use it to establish something right?

Any thoughts?
