What Is Nitrogen Loss?
Article Categories: Blog Icon BLOG, CANADA, US
Nitrogen loss can be a serious problem impacting yield potential and return on investment. Depending on the soil type, nitrogen fertilizer is susceptible to losing more than 50% of its nitrogen through ammonia volatilization, denitrification and nitrate leaching.

THE NITROGEN CYCLE

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

ENHANCED EFFICIENCY FERTILIZERS CAN REDUCE NITROGEN LOSS

While fall applications of nitrogen can help take pressure off spring field work, allowing for more timely planting, these applications are still at risk of nitrogen loss. We’ve debunked two common myths concerning nitrogen loss in fall-applied nitrogen to help ensure growers are maximizing their nitrogen fertilizer inputs.
