What is Nitrogen Loss
The process of keeping nitrogen available to nourish crops is complicated. Variables such as weather, soil type and soil microbe population can all have an impact on how nitrogen can be lost. This diagram illustrates how nitrogen is made available for plants as well as the various mechanisms for loss.
AMMONIA VOLATILIZATION
Above ground nitrogen loss
Occurs when the soil’s urease enzymes break the urea molecules into ammonia gas
Can take place in every soil type
NITRATE LEACHING
Below ground nitrogen loss
Happens when negatively charged nitrate is moved below the plant’s root zone by percolating water
Most common in sandy soils
DENITRIFICATION
Below ground nitrogen loss
Occurs when nitrate nitrogen is converted back to gaseous forms
Most prevalent in soils that are poorly drained or become waterlogged
