Salt increased the yield of kale by about i ton/acre in five out of six experiments on soils which were not seriously deficient in available potassium. There were frequent negative interactions between salt and muriate of potash. Fertilisers, other than muriate of potash, did not materially influence the uptake of potassium. Salt and potash tended to depress the calcium and magnesium levels, but only slightly. Salt did not increase phosphorus utilisation although the soils were phosphate‐deficient. Salt and ammonium sulphate greatly increased sodium uptake and muriate of potash markedly reduced it.
