Whirl I have cattle so no worries on the blocks after shft a block is not going to be an issue and they last alot longer than loose salt. A 10kg block of salt is like $ 6-8 a block at farm store sat at whole sale is $12 for the white death.
I get the consealment of it melted into ground…. but it kills the grasses it’s poured on and for me I want the deer moose and elk to be in my field before I take them. Otherwise can’t use tractor to process them.
We plant sweet pea (did terrible this year) at the fencing for them to forrage. For bears…. well they just wander in every once in awhile to snack on whatever is handy. Not fond of bear meat though with pork it does make decent sausages.
