A study was made of the relationship between soil properties and the growth of quaking aspen on 16 sample plots in northern Minnesota. The soils of this region show wide variations in their levels of replaceable bases and other associated fertility factors. The average annual growth of aspen on soils with high levels of calcium, magnesium, potassium, and nitrogen was over 4 times greater than the average annual growth on soils having a lower base status and nitrogen content. Analyses of foliar samples and aspen litter showed a close relationship between the supply of exchangeable bases in the soil on which the trees had grown and the level of calcium, magnesium, and potassium in the tissues of quaking aspen. Although the purposes of the study was primarily reconnaissance, the results show quite conclusively the extreme importance of soil characteristics in determining the quality of a site for aspen growth.
