How far away to put horse manure?

When applying horse manure to gardens or fields, it is generally recommended to keep it at least 20-30 feet away from water sources like streams, ponds, or wells to prevent contamination. Additionally, if you’re using it as fertilizer, allow the manure to decompose for several months or compost it to reduce pathogens and odors. Always follow local regulations and guidelines for manure application to ensure environmental safety.
