Half of nitrogen from feedlots is lost to ammonia emission

Feedlots have come a long way in reducing harmful greenhouse gas emissions in recent years.

But a new federal research study has found that nitrogen losses in feedlots are still significant — and can significantly affect the bottom line.

“We’re losing about 50 per cent of the nitrogen to ammonia loss in a feedlot, and there are economic implications of that,” said Sean McGinn, a research scientist at the Lethbridge Research and Development Centre.

“Once you realize that 50 per cent of the nitrogen is lost to ammonia emission and that nutrient is then not available for crop growth, that can be recognized as real cost savings.”
