Hi Sanetters,
I'm not sure just where this story fits in....
but a number of years ago my plant science teacher was relating a story
about a local dairyman who lost some cows after he turned them loose in the
early spring to graze in a field that annually floods. The area is part of a
lagoon system that can be under water for up to a month solid every winter
due to flooding. Apparently a number of cows died from eating the first
growth forage in the field because it had a high level of nitrites (as
opposed to nitrates) due to the anaerobic winter conditions, and the nitrite
level proved toxic to the cows.
