Distribution of Free Iron and Organic Carbon as Related to Available Water in Some Forested Sandy Soils1

  1. Stephen G. Shetron2



The amount of available water (0.1–15 bar tension) in the B21 horizons of six sandy soil series increased as amount of free iron and organic carbon increased. Soils of the Typic Udipsamment subgroup had the lowest, and soils of the Typic Haplorthod subgroup the highest available water retention values. Retention of available water in the C horizons of these soils was positively correlated with free iron and specific surface. Cubic meter volume growth per hectare per annum for hardwood and pine stands increased as amounts of free iron, organic carbon, and available water increased.
