| Summary: | Since shortly after the formation of the Forestry Commission, experimental plantations have been made on the worst types of deep peat, and the best of these now form stands up to 35 feet high. With the development of mechanical methods of ground preparation and the use of phosphatic fertilizers, the afforestation of poor quality deep peat has been shown to be a practical possibility. The object of the present investigation has been to study the changes that have taken place in the peat as a result of 30 years tree growth, and hence to determine whether further mineral fertilization, or modification of ground preparation techniques and silvicultural treatment will be necessary in the future, and whether there is any evidence which would render inadvisable the large scale afforestation of deep peat in the west and north-west of Scotland.
