Abstract
An envelope for surrounding the roots and soil of a tree which is to be transported and transplanted at another location is covered on one side with a flexible sheet of polyurethane foam. Pref. polyurethane which has been prepd. from polyesters is used, as this material decomposes more easily in the earth and yields ammonia which acts as a fertiliser. Perf. the sheet is itself impregnated with a nutrient or a fertiliser. Pref. a metal grid soaked in plastics material is included.
