In a cow-calf operation where cattle are often fed in pens for a portion of the year, pens are generally cleaned at least annually to remove accumulated manure and bedding. While backgrounders and feedlots have enforced protocols to manage and store manure, general guidelines apply to all producers who are handling and storing manure.

Manure offers a long-term source of nutrients that can influence soil properties, increase soil carbon and nitrogen, and alter soil phosphorus and potassium concentrations along with other nutrients. Best management practices must be followed across all sectors from cow/calf to backgrounders and feedlots.

Though specifics vary by region, recommendations include:

â–ªavoid short term stockpiles on sandy soils, rock quarries, or gravel pits

â–ªuse a concrete pad if possible, to prevent nutrient leaching into soil and groundwater

â–ªhave runoff containment, such as a lagoon

â–ªensure that stored manure areas are at least 60 metres from drilled water wells, 400 metres from municipal wells and 120 metres from all other wells, streams, rivers, lakes, and ponds

â–ªthe slope of the land where manure is stockpiled must not be greater than 3% to avoid overland runoff

â–ªkeep winter feeding sites and corrals at least 30 metres from bodies of water

Treatment of stored manure can include stockpiling, composting, drying, and less commonly, separation and filtering. These methods reduce moisture content, which reduces volume and odour. Stockpiling (no treatment), composting and drying are the most common treatment strategies in beef cattle operations.
