Abstract

If you want to understand how nitrogen behaves in the soil, it pays to think about two things: water and time. These two factors control when and how much nitrogen can be lost from soil. They also help explain why some landscapes accumulate the nitrate form of nitrogen while others do not. Join us as we discuss how nitrogen moves through soils, how we can control its losses, and the surprising connections between nitrate, road salt, and nuclear testing.
