Abstract

After three growing seasons, green ash had produced 7,342 pounds per acre of above-ground dry matter compared to 3,572 for oak. Of the total biomass, ash had 53% in the bole (wood plus bark), 22% in old branches, 21% in leaves and 4% in new growth; oak had 50%, 21%, 24%, and 5% in the same components. These proportions changed after leaf fall. Concentrations of N, P, K, and Mg followed the general order of: leaves > new growth> bole bark and branch bark> bole wood and branch wood. Calcium concentrations were highest in bole bark and branch bark followed by leaves, new growth, and bole wood and branch wood.
