Recently, numerous studies of soils with fragipans have been conducted in Ohio.This chapter is an attempt to collale the Ohio data with that available in the literature in order to formulate a general theory applicable to the formation of fragipans. Six pedons were selected to illustrate various pedogenetic scenarios in Ohio resulting in fragipan development and contributing to the development of our theory. Based on data for these pedons, it is concluded that fragipans form at weathering discontinuities originating either as a result of a wethering front or due to the occurrence of a lithologic or chronologic discontinuities due to an interaction between acid weathering products and components present in relatively unweathered material to form a bonding agentThis theory is presented for additional testing and evaluation |
