Effects of zero, light or heavy weekly leaf fertilisation with nitrogen throughout the 1962 growing season on leaf and bark N content as well as growth of cankers initiated by artificial trunk infection with N. ditissima on 1 August 1962 were measured in September (leaf N), October (bark N) and late November 1962 (canker).
