Nutrient Deficiencies



Locations of Nutrient Deficiency Symptoms

The table below is a guide to the symptoms of possible nutrient deficiency in a range of crops.  The nutrients mobility within the plant will help identify the nutrient deficiency.  For example symptoms caused by deficiencies of an “immobile” nutrient will occur on the upper or younger leaves.  The older leaves will remain green and free of symptoms because these immobile nutrients do not move or translocate from them.
