Abstract
Extract
The July 1973 issue of the New Zealand Journal of Agriculture discussed the Tama revolution. No mention was made of the possibility of nitrite poisoning in cattle grazing ‘Grasslands Tama’ (tetraploid westerwolds) ryegrass. There have been deaths from nitrite poisoning in cattle grazing Tama ryegrass and other crops in many districts this year, and this experience with a brief discussion on nitrite/nitrate poisoning is presented for the guidance of those who may be considering Tama ryegrass as a fodder crop.
