WebCalcium, potassium, and nitrogen concentrations in both the soil and plant can affect boron availability and plant function, the calcium:boron (Ca:B) ratio relationship being the most important. Therefore, soils high in calcium will require more boron than soils low in calcium. The chance for boron toxicity is greater on low calcium-content soils. WebJan 1, 2012 · Boron toxicity is a common problem for many crop plants, especially those growing on soil with high levels of boron and low rainfall. Boron is transported through the plant in the xylem and boron not absorbed by other tissues is deposited at the end of leaf veins where necrosis develops.
