Аннотация: This book was made an attempt to take full account of three recent developments in forest practice: a large scale use of chemicals in the production of nursery stock and in other phases of silviculture; insufficient increament of stands and plantations on soils of depleted fertility; and erratic results obtained with partial cuttings conducted according to the empirical rules of silvicultural art.The successful handling of these problems requires not only a grasp of technicalities, but also a knowledge of basic relationships, a knowledge of basic relationships, a knowledge which allows the analytical information to be synthesized into a conclusion of practical significance.
