a lot of work
With intensive grazing there are lots of small chores that can look like 'a lot of work' to folks who graze conventionally.
But all those daily little jobs mean fertile soil with good rainwater retention, and a wide mix of healthy forages, and lots of biomass, and happy, healthy cows that don't need meds or wormers -- this, instead of pasture irrigation systems, spraying and drilling new pasture, spreading fertilizer, and bringing in stock for regular dosing. .
We'll take the daily small chores, thank you.
