By Brittany Elek and Thomas Pederson Overview Essential nutrient for plants Warington study 4 Deficiency High rainfall amp solubility of boric acid Inhibition of root elongation leaf expansion fruit sets. 2 Lack of boron stunts plant vegetative growth and greatly reduces root growth right Decreased root growth reduces the plants ability to obtain water and nutrients from the soil Fig 3 Boron deficiency in alfalfa BORON. . Discovered in 1808 by Sir Humphrey Davy. Brittle, black semi metallic substance. Tends to form planar compounds. THE USE OF BORON IN LUBRICANT FORMULATION. BORON NITRIDE (BN). Planar hexagonal structure. The Periodic Table gives us SO much information about the world around us, but first you have to know how to read it!. Each of these little squares tells us about one specific element.. Reminder!: An Element is a pure substance made of all the same type of atom!. Occurrence Concentrations vary widely and depend on the surrounding geology and wastewater discharges. For most of the world, the concentration of boron in drinking-water is judged to be below 0.5 mg/ nanojunctions. Navarre . statam. Research: . Mauricio . Terrones.
