Soil and Plant Moisture Relations of Red Pine Growing on a Shallow Soil1

  1. R. F. Fisher and
  2. E. L. Stone2



The relationship of plant moisture status to soil moisture content was studied in a 25-year-old red pine, Pinus resinosa Ait., plantation on 60 cm of channery silt loam soil over fractured siltstone bedrock. Two of the four-tree plots received summer rainfall; rainfall was excluded from the remaining two plots by a plastic ground covering. The relative turgidity and needle moisture content of current- and second-year needles were measured; only the second-year needle relative turgidity was significantly correlated with soil moisture content. Wood moisture content was not correlated with soil moisture content. The dry weight of current-year needles was closely related to the soil moisture availability during the period of growth. The degree to which the underlying bedrock was fractured, allowing roots to penetrate, was a primary factor in survival.
