Nutrient Benefits
Antagonism
High N levels can reduce the availability of:

- Delayed maturity
- Decreased resistance to disease and pests
- Smaller fruit
- Lower yields
- Shorter storage life
Factors Affecting Availability
- Light or sandy soils where nitrate nitrogen is leached
- Water logged soils
- Soils with structural problems as a result of poor aeration
- Mineral soils low in organic matter
- Nitrogen depleted soils
- Soils where ammonium has been applied to high pH soils (free ammonia)
Sensitive Crops
All crops
