Good cultivation practices to minimize nitrogen losses:
- The application time and quantity should be adapted to the requirements of the crop to avoid untimely and incorrect nitrogen additions:
- The addition is planned and distributed based on the needs and development stage of the crop.
- No addition outside the growing season or before set-aside.
- Addition of optimal quantities according to a fertilization plan.
- Adjustment of the fertilization program during the growing season, based on analyses.
- Balanced nutrition of plants in all nutrients, which promotes the effectiveness of nitrogen applications.
- Vegetation cover throughout the year (intercropping, nitrogen-fixing plants), to avoid periods with bare soil.
- Effective use of organic fertilizers of animal origin and sewage sludge.
- Application in spring when plants can make better use of organic nitrogen.
- Addition using sophisticated techniques that allow immediate integration to reduce losses.
- Incorporating straw to immobilize inorganic nitrogen before winter.
- Cultivation of the soil in spring to avoid the mineralization of nitrogen that follows autumn and winter cultivation.
Inorganic fertilizers contribute about 10% of total ammonia gas emissions, but there are differences between different types of fertilizers.
Inorganic fertilizers contribute about 10% of total ammonia gas emissions, but there are differences between different types of fertilizers. Uria and inorganic ammoniacal fertilisers have a higher gas emission potential under certain conditions. For mineral fertilisers the average loss in the form of ammonia gas ranges from zero (for pure nitrate fertilisers), 1-3% (for ammonium nitrate fertilizers), 8% (for urea/ammonium nitrate solutions) and more than 15% for surface-applied urea (ECETOC, 1994).

Ammonia evaporation increases from :
- High soil pH
- Low regulatory capacity of H+
- High temperature/radiation
- High wind speed
Ammonia evaporation is limited from :
- High filtration capacity
- High mineral content of clay
- Increase in organic carbon (> 1.5% organic carbon)
- Adequate soil moisture
- Precipitation / irrigation after application
- Incorporation into soil
