How soil conditions & chemistry affect nitrogen loss

Nitrogen loss is the topic today on the Advancing Nitrogen Smart podcast. Soil conditions and chemistry are factors that make nitrogen prone to loss, but how does the N loss process actually happen? What's left over in the field after that process occurs, and where does the lost nitrogen go? What do denitrification, leaching and volatilization mean? How can the 4 Rs (right rate, right source, right placement, right timing) help growers minimize risk? How do nitrification inhibitors, microbes, and soil types fit in to the picture? All that and more in today's conversation.
