The phosphorus content of the leaves of glasshouse tomatoes, carnations and winter lettuce was decreased by additions of potassium sulphate and lime to the soil, except at low levels of soil phosphate. Liming also increased the amounts of phosphorus extracted by 0.5N‐acetic acid and by Morgan's solution. The relation between phosphorus in the plants and in the acidic soil extracts was thus markedly affected by liming the soil. The effect of pH on the content of acid‐soluble phosphorus in the soil is discussed.
