B.S.P.). Seedlings were grown from seed with a conventional, fixed dose fertilizer (10mg N seedling−1) or an exponential nutrient loading regime (75mg N seedling−1). The following spring, seedlings were exposed for two weeks to either ambient (370ppm) or elevated levels of CO2 (800ppm) and then planted in the field; seedling growth was followed for the next six years. Exponential nutrient loading increased seedling height, stem diameter and leader growth, with the largest increases in height and leader length occurring in the first three years after outplanting. Carbon loading increased seedling height and leader length, but only in seedlings that had been exponentially nutrient loaded. A combination of carbon and nutrient loading increased shoot height 26%, stem diameter 37% and leader length 40% over trees that received neither treatment. These results demonstrate that the growth enhancement seen under exponential nutrient loading is maintained under field conditions for at least six years. Carbon loading just before outplanting was a useful supplement to nutrient loading, but was ineffective in the absence of nutrient loading.
