Abstract
Samples 38 pairs of red pine (Pinus resinosa Ait.) plantations and adjacent deciduous stands. The deciduous stands had greater mass of Ca in the overstory and higher Ca concentration in the 0- to 4-cm mineral soil layer. Both Ca concentration and mass were greater in lower layers of the rooting zone (to 32 cm) under pine. Neither mass of Ca in the forest floor nor in mineral soil to 100 cm differed between types. Contary to earlier reports, total system Ca was greater in deciduous stands. Deeper soil layers provide minimal Ca to forest stands during a normal rotation. The initial quantity of Ca in the near-surface soil and the input-output balance determine Ca status of a site, but the role of deciduous forests in conserving the inputs deserves further scrutiny. -from Authors
