Roles of nutrients in nuts by crop growth stage

Nutrients play essential roles throughout a crop growth cycle. Find out the role of specific nutrients in nut growth and development by growth stage.

almond bloom Budburst - flowering

  • Nitrogen and potassium – reactivate and promote the early growth of new plant tissues leading to maximum tree productivity
  • Phosphorus – to build tree reserves and maintain root development
  • Calcium - boost reserves and provide a strong platform for high yields
  • Boron and zinc* – if not already applied post-harvest - to maximise flowering and strong fruit set 
  • Iron – If deficiencies are seen


almond fruit set Fruit set

  • Nitrogen – maintain leaf development and fruit development
  • Potassium – to maximise growth and early fruit uptake
  • Calcium – maintain strong growth of healthy tissues
  • Sulphur – to maximise nitrogen efficiency in the tree and improve oil and fat content of the fruit
  • Boron and zinc* – to maintain growth and development of the flower and developing fruit tissue


almond fruit fill Fruit fill - maturity

  • Potassium – to build fruit quality during this critical phase
  • Nitrogen – in lesser amounts to maintain growth alongside higher rates of potassium
  • Calcium, zinc and boron* –to help improve fruit integrity and improve quality and storability


almond field post harvest Post-harvest - prior to leaf senescence

  • Nitrogen and potassium – to build tree reserves and hence be available for new growth once it commences in the following season
  • Calcium and phosphorus – to revitalise rooting and ensure strong availability for the following season
  • Boron and zinc* – to build levels in tissues and produce strong spring budburst and flowering in the following crop

* Foliar spray preferred
