Micronutrients

Micronutrients reinforce and supplement the strong plant growth and structures provided by macroand secondary nutrients.

Most micronutrients influence growth.  For example, manganese (Mn), iron (Fe) and copper (Cu) all influencephotosynthesis, the process whereby plants use sunlight for growth.

• Iron deficiencies are common – for example in stone fruits – where, the effect is to reduce the manufacture of chlorophyll.  As a result, crops struggleand younger leaves develop a severe yellowing or chlorosis.

• Boron (B ) is needed for the development of shoots and roots, and essential during the flowering and fruiting phases of crops.

• Zinc (Zn) is needed for the production of important plant hormones, like auxin. Zinc deficiency leads to structural defects in leaves and other plant organs.

• Molybdenum (Mo) is involved in plant enzyme systems that control nitrogen metabolism.
