Abstract

Fertilization and thinning are being used to rehabilitate hardwood woodlots of southern Ontario for the production of high-grade hardwood lumber. Variable conditions of tree quality, species composition, and age necessitate that experimental treatments be evaluated on the basis of individual tree responses. A method is described for the selection of trees and their allocation to treatments according to a competition index. Soil perfusion techniques were used to assay the degree to which different levels of nitrogenous fertilizer might increase the amount of nitrogen available to the trees from forest soils with brown forest to gray-brown podzolic profiles.
