Calcium deficiency on orange made worse by
- Acidic soils
- Sandy or light soils (leaching)
- Acid peat soils
- Soils rich in sodium
- Soils rich in aluminium
- Drought conditions
- Fruit high in nitrogen or potassium
- Large fruit
Calcium is important for
- Leaves are properly formed and remain throughout cycle
- Overall tree growth is more vigorous
- Yield often increases
- Fruit-size more regular and uniform
- Better quality fruit
- Better skins - less 'Albedo Breakdown' (creasing)
Yara recommended fertilizers for Calcium
YaraLiva® CALCINIT™15.5-0-0
Oranges: For young trees up to 2 years old apply 1.5-2 lbs YaraLiva® Calcinit® 15.5-0-0 19 Ca/tree/year. For mature trees apply 900-1400 lbs YaraLiva® Calcinit® 15.5-0-0 19/acre via fertigation. Apply pre-bloom for best results. Utilizing YaraLiva® Calcinit® for part or all of the nitrogen needs supplies the crop with fast acting nitrate nitrogen and supplies soluble calcium in proper ratio with nitrate nitrogen. Calcium is important for cell wall strength and to limit physiological disorders such as cracking and creasing. Consult with your agronomist for local recommendations.
