Soil Properties and Chemical Composition of Tree Leaves in Southern Indiana1

  1. J. R. Crum and

Soils developed from gray-green shale in southeastern Indiana and neighboring states have low forest site quality and low productivity for farm crops. In this study the Rarden soil, formed from gray-green shale, was compared with the Trappist soil (moderately productive), developed from black carbonrich shale, and the Hickory soil (highly productive), developed from Illinoian till. The soils were on westerly-facing shoulder and backslope landscape positions. Crystals occurring as small patches in the B3 of Rarden were identified as barite (BaSO4) in prismatic, hexagonal-tabular, or octagonal-tabular shapes. A pedon of the Rarden soil contained about two-thirds as much extractable Ba as Ca. Leaves from three hardwood species were analyzed for 15 elements at each site. Flowering dogwood (Cornus florida L.) leaves accumulated Ca and, especially, Al to a much greater extent than sugar maple (Acer Saccharum Marsh) or white oak (Quercus alba L.), whereas sugar maple tended to accumulate Mn. Leaf samples collected in July and September showed no significant differences in concentration of the major nutrient elements P, K, and Ca, but did show differences in concentration of several of the minor nutrients. No evidence was found that Ba or other minor elements caused toxicities or deficiencies. The contents of extractable Ca and Al in the soil were reflected in their concentrations in flowering dogwood leaves.
