i know this is an old question...but here is
what we do for the dips and holes that get worn into the ground around gates and
feeders. We lay down DG (decomposed granite). There is lots of it
here in Nevada and it works well without any ill effects on the
horses.
My Dad is wanting to dump a bunch of lime in the massive
mudhole in front of the pen gates. Is this a bad thing to do around
horses? Can it scald their hooves?
