This has been true for many, many decades:

This is "normal" - clearing, ploughing, seeding are short intensive bursts, harvesting the same.
Much of the rest of the year it's maintaining equipment, fences, and twidding thumbs, except that's boring and unproductive and so there are "filler jobs" - running a small business (welding, rousting, wall building, landscaping), renting properties, etc.
It goes wider than farming; for decades most rural areas I've lived and worked in have had most of the locals having several overlapping jobs each - too few people, much to do, no one task takes up full time, etc.
The science side is Ag and soil, lots of GIS IT, asset tag systems for records (individual animals and seed plots, etc), robots, laser scanning for wool fibre, ... (long list).
These are not enterprises that can managed by idiots.
Sure, you have drenching days, tagging days, etc but once the fences and water are in they're set and forget for most of the time in that most of the days in a cycle are mostly free to interleave in other activities.
Even cleanskin cattle (in the Northern Territory) fall into "keep an eye on them" and then there's a muster - there's work there for someone to keep the bores and yards up to spec and spending a few days here and there culling camels but, again, they tend to look after themselves on the right land - so much so that the pressing work is keeping them in check (via musters) so that they don't degrade the land.
