Physical and chemical properties of surface soil beneath eastern redcedar trees in pine plantations in Connecticut were found to be different from those beneath adjacent pines. Properties of the surface soil beneath redcedars were apparently influenced by the specific chemical nature of the cedar leaflitter, its decomposition products, and subsequent' incorporation in the soil by earthworms.
