Millet containing from to 27 ppm Mo or 10 to 11 ppm Cu was produced by supplementing the nitrogen fertilizer with different amounts of sodium molybdate and CuSO4. Control unsupplemented forage contained an average of ppm Mo and 4 to 13 ppm Cu. The rates of nitrate and nitrite reduction in sheep and cattle were not affected by consumption of the supplemented : David Thomas Buchman.

Some factors affecting the activity of nitrate reductase in cauliflower plants grown in different nitrogen sources and molybdenum levels in sand culture. Plant Physiol, – (). Google ScholarCited by: Nitrate buildup in plants Under normal growth conditions there is little nitrate buildup in the plant even though the plant's roots are absorbing large amounts of nitrate, because the stem and leaves normally convert (i.e., reduce) nitrate to protein (ammonia then amino File Size: 1MB. NITRATE TOXICITY The primary nutrient form of nitrogen in most soils is nitrate which is a normal compound found in many plants. It can be found normally in various grazing and forage crops, soil, and water. Under certain circumstances, nitrates can accumulate to abnormally high levels and become very toxic to ruminants. The metabolism of molybdenum is affected by copper and sulfur intake in some species. In ruminants, copper generally has a beneficial effect on the symptoms caused by excessive molybdenum, and thiomolybdates increase the excretion of copper. Both positive and negative effects of the interaction between these three elements have been reported.

  The complex threeway interactions of copper, molybdenum and sulphur are discussed and the different contributions made by different sulphur compounds, in particular sulphate and sulphide, are outlined for ruminants and non-ruminants. The ruminal conversion of sulphur compounds to sulphide is seen as a key factor in determining the relative sensitivity of ruminants to molybdenosis since Cited by: In the absence of molybdenum, nitrate reduction slows down, which results in nitrate accumulation in plants. On the other hand, adequate molybdenum supply in soils can ensure a reduced nitrate content of leafy and root vegetables and in general, all fresh-cut agricultural by: Many species are susceptible to nitrate and nitrite poisoning, but cattle are affected most frequently. Ruminants are especially vulnerable because the ruminal flora reduces nitrate to ammonia, with nitrite (~10 times more toxic than nitrate) as an intermediate product.
