Be on alert for nitrate levels in silages

Ontario Field Crop Report for the week of July 29

This is most common in corn, but sorghums, sudangrass, millets, cereals, and Italian ryegrass can all accumulate high levels of nitrates and potentially cause nitrate poisoning in livestock. Why are high nitrate levels a problem? Nitrates (NO3-N) are converted to nitrites (NO2-N) in […] Read more
