Recently, the owner of a local stable in my area added shredded up packing peanuts to the indoor arena footing. My question is, has anyone heard of this before? Is this a thing? What would it do to improve the footing?
I believe the packing peanuts were the polystyrene type, not the biodegradable type and it sounds like he just got some packing peanuts, shredded them up and spread them around. This is in an indoor arena with sand footing that has historically been too deep and with a questionable base.
I have heard of all sorts of additives to improve arena footing; wood mulch products, rubber, felt and fiber to stabilize footing and chemicals like magnesium chloride to help retain moisture in the footing. I have never heard of adding polystyrene packing peanuts. They don’t absorb water, they will probably get crunched up into tiny useless pieces, and they are so light I am told they are already blowing away all over the farm.
What am I missing? Why would someone add packing peanuts to a ring?
