Do the totems for crops stack?

[Dominic]

Both separately and together.
ie if i had crops under 2 spring totems (4% to havest extra crop) would i get 8% chance to harvest extra crop

and/or

separate totems for ex combat and mining totem would the crops then give xp for both classes?

I tested using 1 totem each (combat, mining, fishing, and spring) and they do stack. it's quite cool to see all the exp bars moving for harvesting crops.

I don't know if the same type of totem stacks with itself. I imagine it does, but haven't tested. Honestly, the way totems and scarecrows have to work together, I almost thing it's not worth trying.
