Our Clean Water Wednesday broadcast from Boone County with Van Wall and Aquacheck, Bob Quinn talks with Iowa Secretary of Agriculture Mike Naig on the importance of tracking nitrogen in soil and having that data available in easy-to-use ways. We are also joined by the manufacturers of Aquacheck all the way from South Africa! Arthur Pickworth talks about the development of their soil moisture and temperature probes and how they worked with Iowa State University researchers to create it; and Dave Mayers dives into the technology they use to get the probe data to your smart device.
