Oooo, I get a bit excited about interdisciplinary techno-plant-and-livestock

Another area that might be easier to break in to as far as work goes is labouring for an irrigation business, kinda agricultural plumbing.

You’ve probably seen pivots[1] and side-roll irrigation systems.

This would put you in more direct contact with the farm operators, expose you to a wide range of agricultural crops, and also tie neatly in to your existing CS skill set with regard to agricultural SCADA (Supervisory Control and Data Acquisition), or Industrial Arduino as I like to call it.

Working for seed processes / distributors and fertiliser and pest & weed control industries could also be another foot-in-the-door move.

this is low key one of the few things that I think of doing for the rest of my life, though my bias is towards seaweed farming and related ecosystems
