115mottles - spots or blotches of different color or shades of colorinterspersed with the dominant color .Mottling in soils usuallyindicates poor aeration and drainage .organic matter - thedecomposition residues of plant material derivedfrom : (i) plant materials deposited on the surface of the soil,and (ii) roots that decay beneath the surface of the soilortstein - a Bhf or Bf horizon that isstrongly cemented by iron andaluminum oxides .It is designated Bhfc or Bfc, depending onthe organic carbon content .parent material - unconsolidated mineral material or peat from whichthe soil profile developspeat - unconsolidated soil material .consisting largely of undecomposedto partially decomposed organic matter accumulated underconditions of excessive moistureped - a unit of soil structure such as a prism, block, or granule,formed by natural processes(in contrast to a clod, which isformed artificially)pedology - those aspects of soil science involving the constitution,distribution, genesis and classification of soilspercolation, soil water - the downward movement of water through soil .Especially, the downward flow of water in saturated or nearlysaturated soil at hydraulic gradients of the order of 1 .0 orlesspermeability - the ease with which gases, liquids, or plant rootspenetrate or pass through a bulk mass of soil or a layer of soil :Since different soil horizons vary in permeability, the particularhorizon under question should be designated .
