Nutrients
Grassland & Pasture - Growth retardation
Symptoms
Light green colour with yellowing of leaf base, reduced growth and sparse ground cover due to lack of nitrogen.
Reasons
Nitrogen deficiency (bottom)
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
