Several experiments are described which examined the effects of different application rates and types of potassium (K) fertiliser on the growth of Sitka spruce on new planting sites. The effects of different times of year of application were also tested. Results confirm that the current prescription of 100 kg K ha-1 supplied as 200 kg muriate of potash ha-1 is correct and that the fertiliser can be applied at any time of year, provided the ground is not frozen or snow-covered.
