I use trace mineral with selenium, SE 90 for deer and elk with good results. Loose and blocks both work
Holy cow dude I put out two 50 pound bags of loose salt and had a salt block w/selenium in one honey hole last year and the elk literally destroyed what was nice level, soft earth. Its a few inches lower all around, and down to bumpy, jagged rocks sticking up. I put what was left of last years block back out there and can't wait to grab it in a few weeks
Put a 50# bag on it now, and another in August and you'll be good to go. No need at all to re-salt every 4-6 weeks.I just dump it on the ground. It will leach into the soil and they will dig it up once they get the top layer off. It will stay there for a long time, even 1 bag. I've seen pictures where they've dug into the soil so deep to get the salt, a deer's butt is all you'll see sticking out.
Once again it depends how many elk are there....I have spots where 50lbs doesnt even get a chance to leach into the ground and is gone in 2-3 weeks..this spot is about 25-35 deer and herd of elk between 6-9 cows and a few lone bulls and bach group of bulls 3-6 bulls
