Key issues discussed/latest findings in the field:
This IUFRO symposium provided a forum on the principles of nutrition in nursery seedlings and
juvenile forest trees. Emphasis was on the development of effective and environmentally sound
technologies to optimize seedling quality and promote reforestation and forest restoration operations.
The first day focused on Nutrition in the Nursery and at Field Establishment and the second day on
Juvenile Stand Nutrition. The program was aimed toward an international audience of nursery and
forest practitioners, scientists, and educators. Of particular interest was the variability in nutritional
requirements and fertilizer responses of forest trees across a range of site limiting factors (e.g.,
drought, vegetative competition, or animal browse).
Conclusions (if possible, summarize key conclusions across presentations):
Enhanced basic understanding of plant nutritional requirements and mechanisms for growth
responses, improved analytical methods of analysis, and advances in fertilizer technologies have
promoted forest plantation establishment success and development of young stands. However,
knowledge of all of these factors needs to continue to be expanded in order to further enhance
productivity of commercial forestry plantations. Restoration plantings represent a very different context
where nutrition may be key for survival on harsh sites and use of an increasingly diverse pool of
species necessitates case-specific prescriptions.
Outlook to future activities (proceedings, future meetings, other):
Selected papers presented at this symposium are scheduled to be published in a special issue of the
international journal, New Forests, in 2013. It was agreed that researchers from this discipline should
meet more frequently in order to continue to debate and advance the science behind forest nutrient
dynamics. Thus, we anticipate that another international symposium on this topic will be held within
the next five years.
Thank you very much for your kind cooperation!

Background information (meeting context):
In 1997, a successful conference was held in Corvallis, Oregon entitled “Forest Seedling Nutrition from
the Nursery to the Field“with speakers representing some of the top experts in the field at the time and
over 175 participants. The Symposium Proceedings are available online at www.rngr.net.
Over the past 15 years, many changes have occurred in the area of plant, nursery, and forest nutrition
including refinements in fertilizer technology, advances in nursery stock quality, and increasing
expectations for juvenile plantation productivity. Thus, this 2012 event is timely to help communicate
these advances and provide a forum to identify future research needs and priorities in this field. The
symposium was organized by Purdue University and USDA Forest Service with support from IUFRO
divisions 1.01.03 (Temperate Forest Regeneration), 1.06.00 (Restoration of Degraded Sites), and
3.02.00 (Stand Establishment and Treatment).
