Grassland - Growth retardation
Symptoms
Light green colour, reduced growth and sparse ground cover due to lack of nitrogen.
Reasons
Nitrogen deficiency
Nitrogen deficiency made worse by
- Low or high pH soils
- 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
- Better synthesis of amino acids
- Improved formulation of co-enzymes and nucleric acids
- Increased synthesis of chlorophyll and ATP
- Thus improved crop vigor and development
