摘要：

Comparison of the soil and herbaceous vegetation beneath young conifers and adjacent open fields identical in prior treatment shows that conifers increase nitrogen availability above their own net uptake. The effect extends a short distance beyond their crowns. The presumed explanation is greater mineralization of soil nitrogen rather than fixation. © 1969 Martinus Nijhoff.
