- Sandy or light soils (leaching
- ) Low organic matter
- Drought conditions
- High rainfall (leaching) or heavy irrigation
- Addition or high levels of non-decomposed organic matter/manure (eg straw)
- Fast growing crops
Nitrogen is important for
- Component of enzymes, vitamins, chlorophyll and other cell constituents
- Essential for crop growth, development and high yields
- Necessary for carotene synthesis and therefore also for root colour
