Nitrogen Needs Assessed More Accurately
mineralization when soilborne bacteria chew up organic matter such as residues left from the previous crop. But that may change, now that Agricultural Research Service scientists have found a way to more accurately assess microbial breakdown of straw and stalks. The new method cuts in half the error
Determining Biochemical Oxygen Demand in Organic Waste Water (.pdf)
Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value. Because of the very high content of organic material in the sample, there is a disparity between the nutrients ratio (C:N:P). The lack of nitrogen (N

The On-Line Detection of Oxides of Nitrogen in Light Hydrocarbon Streams
. NOX (NO and NO2) in the olefins processing train is a safety concern. There is a possibility of accumulation of unstable liquid or solid nitrogen oxide (N2O3) and nitrogen oxide-organic solids in the cold processing equipment. In the Cold Box of ethylene production plant at temperature, 130 C
UAN Concentration Analysis Using Anton Paar Density Meter and Refractometer (.pdf)
UAN is a solution of urea, ammonium nitrate and water that is used as a fertilizer. Both fast acting and long lasting nourishment is provided by three forms of nitrogen. These are ammonic nitrogen, nitrate and the water soluble organic nitrogen in urea. Typically, UAN is analyzed to determine
Rice Yield Mystery Solved? Key clues revealed about declines in Asia
A high-tech look into how nitrogen interacts with organic matter and decomposing crop residues in submerged soils may have confirmed the cause of a potentially serious problem facing Asia's rice farmers. Growers of lowland rice ( ) have described significant declines in yield after several years
