Nitrate and Prussic Acid Toxicity in Forage
Cooperative Extension Service • Kansas State University • Manhattan Nitrate toxicity Nitrate is a natural product formed from the oxidation of organic compounds. Most of the soil nitrogen absorbed by plant roots is in nitrate form. Normally, nitrate in a plant is rapidly converted to amino acids by the enzyme nitrate reductase. This reduction requires energy from sunlight, adequate water, nutri...
متن کاملManagement of Nitrate and Prussic Acid in Forage Crops
The two factors of drought conditions and export markets are focusing recent attention on nitrates and prussic acid in forages. During normal years, nitrate-nitrogen (NO3-N) taken up by crops is quickly converted into protein. When forages grow under drought stress, however, they tend to accumulate nitrate. Alternative forages such as sorghums and sudans tend to accumulate even higher levels, w...
متن کاملGas migration through cement slurries analysis: A comparative laboratory study
Cementing is an essential part of every drilling operation. Protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. Failure in this task results in catastrophic events, such as blow outs. Hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...
متن کاملNitrate reductase for nitrate analysis in water
Nitrate analysis in water is one of the most frequently applied methods in environmental chemistry. Current methods for nitrate are generally based on toxic substances. Here, we show that a viable alternative method is to use the enzyme nitrate reductase. The key to applying this Green Chemistry solution for nitrate analysis is plentiful, inexpensive, analytical grade enzyme. We demonstrate tha...
متن کاملInterpretation of Forage Analysis Reports
Forage analyses are a valuable tool for determining the economic value of forages and for formulating efficient and profitable rations. To be useful, forage analyses must be determined accurately and interpreted correctly. The sample submitted must truly represent the feed being analyzed and the forage analyses must provide information that is relevant. There are reliable and repeatable methods...
