Need to break up limestone screenings in arena

[ponytug]

Gypsum helps with open up the pore structure in clay soil, but as far as I know won't do anything for limestone dust in an arena, other than adding dust.

Nice article on footing selection here, though arena footing discussions can end up sounding a lot like differing car aficionados talking at each other at times. Different strokes for different folks.

All the best,
