Leaves show slight distortion, stems are abnormally thick and often the growing points die.
Made worse by
Sandy soils. Alkaline soils. Soils low in organic matter. High levels of nitrogen. High levels of calcium. Cold wet weather. Periods of drought.
Germination of pollen grains and fertilization. Adequate seed set and yield. B requirement relatively low.
Boron Deficiency Cereals have a low requirement for boron and if B fertilizers are given to crops in the rotation then cereals will unlikely exhibit deficiency symptoms. (photo: oat)
