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
