Q: I'm having trouble with ice in my horse paddocks. How can I remove the ice?
A: Ice is a problem in horse paddocks as falls and slips can lead to serious injury. The best solution is to remove the horse from the paddock, until the ice melts, but few horse owners have that option. Sand can be helpful to increase traction. However, it is ideal to not feed the horses in the area where the sand is spread to minimize the risk of ingestion.
Straight salt can speed the melting of the ice if temperatures are not too cold. There is no research documenting the effect of salt on horse hooves, but pure salt should be used in moderation as a precaution. If using pure salt to melt ice, make sure the horses have an alternative source of salt to reduce ingestion off the ground. A mixture of sand and salt should not be used in horse paddocks due to the chance of horses accidentally ingesting the sand via their interest in the salt.
Other options like shavings, hay, and straw tend to slide over ice and do not provide additional traction. Small rocks can provide traction, but can be accidentally ingested or become lodged in hooves. To reduce water/ice in the future, improve the grade, install gutters on the barn, and reduce the amount of manure in the paddock.
