    Description

    Volume growth response to 200 Ib of nitrogen per acre applied as urea or ammonium nitrate was monitored for 4 yr in an 80-yr-old, site I, Douglas-fir stand. Fertilization increased gross total cubic growth by 20 percent over the controls. Response to urea and to ammonium nitrate was similar. The rapid volume growth on the control plots, 34 2 ft 3 per acre per year, plus the substantial increase in growth on the fertilized plots, indicate the desirability of delaying final harvest of this stand.
