A 15-year re-measurement of a study designed to identify the optimum timing and duration of herbaceous vegetation control in plantations of four commercial conifer species was completed in northern Ontario. Few differences were revealed in conifer growth when contrasting early and delayed timing of vegetation control. Conversely, each conifer species responded positively to increased duration of vegetation control, with stand volume gains of up to 209% achieved with four to five years of vegetation control following planting. Compared to earlier assessments, the timing of vegetation control appeared less important than duration. Diminishing returns in the fastest-growing species (jack pine [Pinus banksiana Lamb.] and red pine [Pinus resinosa Ait.]) are consistent with intraspecific competition related to the onset of crown closure in these stands. Quantification of a suite of soil nutrient pools along the gradient of increased duration of vegetation control indicated that the more intensive levels of vegetation control did not adversely affect the assessed soil nutrient pools in red pine or jack pine, but a cautionary approach should be considered for white pine (Pinus strobus L.) and black spruce (Picea mariana [Mill.] BSP), where some declines were evident. Vegetation control for two to three years following planting should maximize early conifer growth potential without adverse longer-term effects on soil nutrient pools.

Abstract. The soil exchangeable pool is classically viewed as the bank of base cations in the soil, withdrawn from by plant uptake and leaching and deposited into by decomposition, deposition and mineral weathering. While largely true, this view ignores the potential large size of other soil nutrient pools, including microbial biomass, clay interlayer absorbed elements, and calcium oxalate. These pools can be sizeable and neglecting them in studies examining the sustainability of biomass extractions or need for nutient return limits our ability to gauge the threat or risk of unusustainable biomass removals. In this short communication, we examine a set of chemical extraction data from a mature Norway Spruce forest in central Sweden, and compare this dataset to ecosystem flux data gathered from the site in other research. We bound the sizes of these pools and discuss them in the perspective of a forest rotation period. Lastly, we highlight the potential for sequential extraction techniques and isotope exchange measurments to illuminate the identify and flux rates of these important, and commonly overlooked, nutrient pools.
