Iron

• Young leaves will show interveinal chlorosis with green veins
• Stunted growth
• Yellowing of leaves (margins  and tips can scorch) will  appear later in season
• Reduced yield and quantity 

• Key role in photosynthesis
• Chlorophyll development  and function
• Plays a role in energy transfer
• Important for the structure of proteins and enzymes 
• Iron increase Nitrogen fixation and use

Apply Iron onto crops grown on high pH or heavily limed soils; crops grown on poorly drained and/or aerated soils; crops grown on sandy soils with a low CEC or soils with high levels of Cu. Soils with low availability of K especially when associated with high K levels are prone to develop Fe deficiency. When high Nitrate Nitrogen (N-NO3- ) is used or present in the soil, Fe deficiency may develop.
