Fall Concerns about Prussic Acid & Nitrate in Sorghums
Dr. Calvin Trostle, Extension Agronomy, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu When our next Row Crops Newsletter is published in early November, a large portion of Texas will have seen heavy frost and a freeze on some sorghums. So, this is good time to update Texas on prussic acid (a plant form of cyanide) and nitrates in sorghums.
