Deep placement of urea in the form of supergranules is often recommended in transplanted rice cultivation as a means of avoiding nitrogen loss in the environment. As ammoniacal nitrogen produced by urea hydrolysis just after deep application is chemically stable in the anaerobic layer of the paddy...

The removal of nitrogen species from the fresh solution was found to be more effective and the process was realized through the chlorine- mediated oxidation. Meanwhile, in the case of the stored urine solution, carbonates derived from the hydrolysis of urea inhibited the ammonia oxidation reaction....
Excess nitrogen (N) fertilizer applied to crops, which discharges to the environment, principally through denitrification, runoff, leaching, and volatilization, results in a waste of resources and pollution. Here, a high-performance loss control urea (LCU) was prepared by adding a loss control agen...
Ni Sheep fed diets containing Ni at 5.32 mg/kg (5 mg/kg of Ni added) and urea at 10 g/kg had greater urease activity (2.5 vs. 12.7 µM ammonia nitrogen/min/mL) and ammonia concentration (66 vs. 88 mg/L) in the rumen Spears et al. [67] Monensin Monensin at 33...
The article offers forecasts on the world exporters' market for imported fertilizers which contain urea and ammonium nitrate mixtures in aqueous or ammoniacal solution for 2009 by ICON Group Ltd. It estimates the market value and the shares likely to be received by countries serving the world mark...
Nitrogen intake was determined from analysis of 24-h consumption of provided foods and beverages. Ammonia and urea flux (Q), protein synthesis (PS), protein breakdown (PB), and net protein balance (NET) were calculated as: Q (g N∙kg−1∙day−1) = [D/(corrected t:t)/24 h ...
