A condition of checked growth associated with chlorotic foliage of Norway spruce and Scots pine on Phragmites peat appeared at first examination to be due to moisture deficiency. Detailed investigation did not support this hypothesis but foliar analysis and, to a lesser extent, soil analysis pointed to potassium deficiency. The appearance of the trees was quickly improved by applications of sulphate of potash.
