50 knots rotation is perfectly fine for a plane that size. A Cessna Skyhawk is certified to rotate at 55 knots fully loaded (and since the stall speed is around 40knots, for specialty take-offs like soft fields it's much lower, 50knots is more than enough).

The part where it's carrying about a metric ton of phosphate while still being able to take off at that speed is really blows my mind.

This plane appears to be a (the?) leading crop duster today. It carries over 4 tons of payload.

Yes but that's got a powerful turboprop.

Well, hope they reinforced the wings, that's a massive weak point for dusters.
