The literature concerning the influence of sodium on phosphorus utilisation by plants has been reviewed together with the frequent suggestions that sodium may be able partially to replace potassium in the nutrition of Brassica crops. It has been found that salt increased the yield of turnips in each of four experiments by greater amounts than did muriate of potash. There were consistent negative interactions between salt and potassium. Muriate of potash greatly depressed sodium uptake and salt increased it by about 50%. Salt was shown to improve phosphorus uptake and there were negative interactions of importance between salt and superphosphate for both the yield and phosphorus content of the roots.
