Establishing windbreaks: how rapidly do the smaller tree transplants reach the height of the larger ones?
landscape rehabilitation arable soil
2015/5/5
The aim of this study is to identify a period of time over which smaller, less costly tree transplants can
reach the height of larger tree transplants and thus offset their performance. The followin...
