Abstract
Trace element deficiencies can have a casual relation to many of the foliage discolorations observed in forest trees. One instance of where this was thought to be true was in trembling aspen in the prairie-forest transition region of Manitoba, where pockets of trees with chlorotic leaves have been observed yearly since 1966. Observations of selected locations and tagging of individual trees indicated that chlorosis occurred in the same trees and the same areas every year. Symptoms were observed yearly in the Anola, Interlake, Westbourne, Russell, and Bowsman areas where calcareous soils were known to be present (Manitoba Soil Survey Reports) but no such symptoms were observed on upland forest soils found in nearby regions of the mixed-wood type (Rowe, 1959).
