Boron Deficiency Symptoms

Boron Deficiency Symptoms

Plants initially may not exhibit obvious symptoms of nutrient deficiencies other than a slower growth rate, which may be due to other factors. When moderate or severe nutrient deficiencies occur, most crops exhibit visible symptoms which are typical for deficiencies of a particular nutrient.
