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
