We return to first principles with a detailed discussion about nitrogen loss on today's Advancing Nitrogen Smart Podcast. The five terms that describe how nitrogen is lost from the soil are: leaching, denitrification, volatilization, crop removal and soil erosion & runoff. But what do those terms actually mean? How does N's chemistry change during loss? Do N loss processes happen at the same speed? How do temperature and precipitation affect N loss pathways? How might farmers hedge against N loss by incorporating the 4Rs into their input planning? All of this discussion and much more on today's show.
