Jim:

Prussic acid won't be a problem util the hybrid sudan gets frosted.  The
main problem during the summer will be the possibility of nitrate
poisoning, which is likely to occur during periods of extremely fast
growth, such as recovery from a drought or a sunny period after extended
cloud cover.  Nitrate fertilization has to be up there, too.  Hevily
manured fields, lots of N use, etc. might point to an area to be careful
on.  Other than that caution, the stuff makes good grazing.  Just don't
let it get too tall before turning the cows in, and leave maybe 3"
stubble.  Our 2" recommendation may be a bit low for sudans.

As far as I know, there is no good determination of what level N will
become a problem at.  May Jerry Cherney, Jim Green, or other researchers
have more info on that kind of thing.

Good luck!
