Term
| Losses of N and the types lost |
|
Definition
leaching- Nirate(NO3-)
erosion- ammonium(NH4+) |
|
|
Term
|
Definition
mineralization- Organic N to NH4+
immobilization- NH4+ to organic N
nitrification- ammonium to nitrate
utrification- dead zone caused from runoff of n |

|
Term
| Which is beneficial immobilization or mineralization? |
|
Definition
mineralization- organic N to NH4+(plant available form)
Immobilization is opposite taking available to unavailable. |
