Conifer Seedling Mineral Nutrition provides a comprehensive review of conifer seedling mineral nutrition and its significance to forestry. The book covers relationships between mineral supply and uptake; the effects of nutrition on seedling growth; an integration of the ideas of T. Ingestad with classical growth analysis concepts; practical aspects of assessing nutrient status and details of fertilizing bare root and container nursery stock; and fertilizing vegetative propagules. The book also describes and illustrates Mycorrhizas, assessing their importance to plantation establishment in an analysis of recent papers reporting field trials. The effects of nutrients on stress resistance and establishment when applied in the nursery and while planting are discussed in the final chapter. It will prove useful to reforestation research workers, nurserymen, and silviculturalists and should be considered essential reading for forestry students.

This book is a printed edition of the Special Issue Seedling Production and Field Performance of Seedlingsthat was published in Forests

This manual offers foresters information to help them understand the performance of spruce seedlings after being planted on a reforestation site. It was written for university students taking a regeneration silviculture class, and foresters and researchers who work with spruce species.

Pinus elliottii Engelm. var. seedlings were selected from 10 seed sources in the eastern and central portions of the natural range of the species. They were grown for 2 years in potted flatwoods soil under six fertilization treatments: two levels of phosphorus (P), all essential nutrients (E) except P, two levels of E plus P, and unfertilized controls. The seedlings differed in growth and nutrient absorption. Trees from coastal seed sources grew slower, especially when unfertilized or fertilized with E or E+P, and accumulated the least amount of nutrients when unfertilized. As long as other nutrients were not limiting, seedlings from middle coastal plain sources grew more rapidly than those from flatwoods sources under conditions of low available P. Large growth increases resulted from fertilization. Phosphorus alone had no effect on tree growth, but the E fertilization treatment significantly increased tree growth. the combined fertilizers, E+P, resulted in greatest growth and nutrient absorption. Phosphorus fertilization resulted in significant decreases in N and K contents, both in foliage and in total seedling.
