Abstract
Sprouting response and soil moisture depletion on aspen plots were compared under four experimental conditions: (a) clearcut, (b) clearcut, stumps sprayed with sodium arsenite, (c) basal injection of sodium arsenite, and (d) control. Nunbers of sprouts varied with treatment for 2 years, but after 4 years the nunbers of sprouts on all plots were about equal. Clearcutting the aspen reduced soil moisture depletion by 3 to 4 inches in a 6-foot soil profile during each of three growing seasons.
