Boron is actively involved in the transport of sugars across cell walls and the synthesis of cell wall material. Because of the impact on cell development, Boron deficiencies will retard new growth and development. Boron deficiency affects a range of crops including root crops, oil seeds, cotton, vines, field brassicas and other vegetables. The primary factors affecting boron availability are soil pH and soil moisture. Crop production on dry soils with pH >6.5 should be identified as being at greatest risk of boron deficiency. Boron deficiency will cause brittle leaves in sorghum, brassica and sugar beet crops. Cotton is also very susceptible to boron deficiency causing distorted flowers leading to flower and boll shedding in severe cases. Pollination is greatly influenced by boron availability. Sufficient boron is required for pollen producing capacity and pollen grain viability. Grapes particularly require adequate boron if impaired fertilisation is to be avoided.
