Iowa State University Researchers Use New Way to Measure Nitrate in Soil
2014-04-11 01:25:00| National Hog Farmer
Source: Iowa State University A team of Iowa State University scientists have measured nitrate in soil with a unique infrared sensor system, opening the possibility of determining the level of this vital nutrient in real time as fertilizer is being applied to fields. The team used a technology, invented at Ames Laboratory, called transient infrared spectroscopy (TIRS) to measure nitrate in soil and then compared those values to ones obtained using traditional soil testing. TIRS works by measuring light emissions in the infrared spectrum after hot air is applied to the surface of the moving soil. read more

ASTM Water Committee Developing Proposed Nitrate Reductase Standard
2014-01-17 06:00:00| Industrial Newsroom - All News for Today
Proposed ASTM WK27289, Test Methods for Nitrite-Nitrate in Water by Nitrate Reductase, will present a means to perform nitrate analysis of water without the use of hazardous chemicals. According to William Lipps, vice chairman of Subcommittee D19.05 on Inorganic Constituents in Water, part of ASTM International Committee D19 on Water, new standard will enable testing laboratories with discrete analyzers to eliminate cadmium reduction methods with a more reliable means to measure nitrate.

Optical Sensors Track Nitrate Levels to the Gulf of Mexico
2013-09-12 23:44:00| National Hog Farmer
Source: U.S. Geological Survey The U.S. Geological Survey (USGS), in cooperation with numerous local, state and other federal agencies currently operates more than 52 real-time nitrate sensors across the nation to monitor nitrate runoff. This cutting-edge optical sensor technology is being used in the Mississippi River basin to more accurately track the nitrate pulse from small streams, large tributaries and ultimately track nitrate runoff all the way to the Gulf of Mexico. read more
