Leaching Requirement for Exchangeable-Sodium Control1

  1. J. D. Rhoades2



A method is described for estimating the leaching fraction required to keep the sodium-adsorption-ratio (SAR) at the lower limit of the plant-rooting zone below some limiting value. The choice of the limiting SAR depends on plant tolerances to sodium and on soil permeability. The method is based on an equation that satisfactorily predicts the SAR values of waters draining from a calcareous soil under various leaching regimes.
