Role of Nutrients by Growth Phase in Stone Fruit
- Nitrogen and Potassium – promote strong early growth of new plant tissues and maximum tree productivity
- Phosphorus – maximize root development
- Calcium - boost root and leaf growth and ensure high yields
- Boron* and Zinc* – maximize bud burst and strong flower development
- Manganese*, Magnesium and Iron – to optimize leaf condition
- Nitrogen – to maintain leaf development
- Potassium – maximize amounts in early fruit
- Phosphorus – fruit set and development
- Calcium – improve fruit quality and minimize fruit disorders
- Magnesium, Sulfur and Micronutrients* – for good leaf quality and reduced fruit drop
- Boron* and Zinc* – maximize growth of young fruit tissues
- Nitrogen – in reduced amounts to maintain growth and sugar accumulation – excess can lead to rots and quality deterioration
- Potassium – improve fruit weight, color and TSS levels in the fruit – but at levels that don’t compete with calcium
- Calcium* – maintain fruit firmness, TSS and storage quality with minimal splitting
- Phosphorus* – improve fruit color and reduce storage disorders
- Magnesium* – maintain fruit firmness
- Boron* alongside Copper* reduces splitting risks
- Nitrogen and Potassium – boost reserves for next season’s early growth
- Phosphorus – maximize bud development, early rooting and new tissue growth in the following spring
- Calcium – maintain high levels in the tree and stimulate new root development after the harvest
- Magnesium* Boron* and Zinc* – replenish reserves to maximize spring bud burst
