Iowa State University Researchers Use New Way to Measure Nitrate in Soil

Researchers from the Iowa State University College of Agriculture and Life Sciences have figured out a way to measure nitrate levels in soil in real time with an infrared sensor. “Nitrate measurement is especially important because it is the dominant available form of nitrogen for growing crops, but is very mobile in the soil.” The newly developed technology is quicker and more accurate than other available options. Next steps include testing different types of soil and designing a smaller tool.
