Maintaining soil fertility, crop rotations based on nutrient usage, etc. are things most don’t think or know about. Even when to and how to turn seeds into food is more complicated (or can be, at least, to do it efficiently) than I think most consider. Edit: also forgot avoiding planting certain things in the same area that are succeptable to the same diseases in following seasons.

It is, as you point out, a lot of breaking down and scheduling tasks with multi-year planning (at least for my scale for rotations and fertility) which is probably why, as an engineer, I kinda dig it.
