Description: The yield and nutrient withdrawal by whole-tree harvest of young bottomland hardwoods has heretofore been unknown. In this study of intensive harvest, samples of chipped whole trees and soil from 16 test plots were analyzed for nutrient content. Eighty-two percent of the stems and 59 percent of the dry weight were green ash. The balance was divided among a number of other species. Dry weight yields averaged 37,114 lbs/a in summer and 31,964 lbs/a in winter. The annual productivity was 1.45 dry t/a/yr, which is comparable to other stands of similar age. Summer chipping removed 176 lbs N, 22 lbs P, 115 Ibs K, 240 Ibs Ca, and 23 lbs Mg/a. Soil reserves of these nutrients were found to be high enough to sustain intensive harvests for many 11-year rotations.
