Research Abstract

The xylem sap method was proposed to evaluate availability of nutrient elements in soil. It makes concentration of nutrients in xylem sap an indicator of their availability in rhizosphere. The method might be suitable to evaluate an availability of heavy metals in rhizosphere and to predict to be producede Cd contaminated rice. However, it is not possible to use evaluating them on the low pH or highly moist soils.
