Tb65: The Commercial Use Of Puckerbrush Pulp, Andrew J. Chase, Fay Hyland, Harold E. Young
Technical Bulletins
This study investigates the potential of several local puckerbrush or weed trees and shrubs as sources of fiber for papermaking. Four different pulping processes were used (sulfate, magnesium bisulfite, neutral sulfite semichemical, and cold caustic) with six puckerbrush species (alder, gray birch, red maple, pin cherry, aspen, and willow). Mixtures of puckerbrush species, and commercial chip-puckerbrush species mixtures were pulped by the sulfate process with the objective of producing a pulp that would be suitable for fine-grade papers. The results produced a good grade of bleachable pulp with adequate physical characteristics for most fine paper grades. The other three pulping …

Tb63: Variation In Foliar Nutrient Concentrations In Red Spruce, C. E. Schomaker
Technical Bulletins
Red spruce (Picea rubens Sarg.) is an important pulpwood species in northern New England and Canada. Management objectives favor this species and the closely related black spruce (Picea mariana Mill. BSP) on many sites. Foliar nutrient concentrations of unfertilized, economically mature, red spruce trees growing on four different sites and over two- and three-year periods are presented here and compared to foliar concentrations reported by other scientists.
