The leaf absorption speeds the rate of accumulation of a toxic ion and may be a primary source of the toxicity. Many trace elements, in addition to sodium, chloride and boron, are toxic to plants at very low concentrations. Fortunately most irrigation supplies contain very low concentrations of these trace elements and are generally not a problem.
There is no Recommended Daily Allowance (RDA) for boron since an essential biological role for it has not been identified. People consume varying amounts of boron depending on their diet. Diets considered to be high in boron provide approximately 3.25 mg of boron per 2000 kcal per day. Diets considered to be low in boron provide 0.25 mg of boron per 2000 kcal per day. The Tolerable Upper Intake Level (UL), the maximum dose at which no harmful effects would be expected, is 20 mg per day for adults and pregnant or breast-feeding women over 19 years of age.
