Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book examines the impact of using fertilizers of varying nitrogen sources on the growth and sustenance of young Western Hemlock trees, a species of increasing importance to the lumber industry in the Pacific Northwest. Conducted by the United States Department of Agriculture Forest Service, the study examined twelve different fertilizers' effects on plant growth over eight months, with a focus on nitrogen as a key growth element. The author notes that despite previous assumptions, there appears to be little difference in response based on which source of nitrogen is applied - with urea and a sulfur-coated urea performing best. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781390023787_0
