116 . Pyrophosphate-Extractable Aluminum and Iron ; organically complexedaluminum and iron were extracted using a 0 .1M pyrophosphate extraction(McKeague, 1967) .A1 and Fe were determined by atomic absorptionspectrophotometry .7 . Particle Size Distribution ; determined using the pipette method ofKilmer and Alexander as modified by Toogood and Peters (1953)withremoval of organic matter by oxidation with hydrogen peroxide .8 . Liquid Limit and Plastic Limit ; by the method outlined by ASTM (1970) .
THE SOILSSoil GenesisSoils are natural bodies present on the earth's surface that arean integral part of the environment .Soils display variation both verticallyand horizontally and by examining these variations soil individuals may berecognized .Soils have evolved from their geological parent materialthrough the action of a combination of soil forming processes, which arecontrolled by environmental parameters or "soil forming factors" .Thesesoil forming factors are commonly listed as being the parent material,climate, biotic agents and topography all acting through time .The variationsin relative importance or dominance of one or more of the soilforming processes such as addition and removal of organic matter,translocationof clays or iron and aluminum, and chemical and physical transformationsresult in the formation of horizons or layers of various kindswithin the~soil body .These horizons differ from one another in suchproperties as color, .texture,structure, consistence, and chemical andbiological activity . The major, or master horizons are designated 0 fororganic layers developed mainly from mosses, rushes, and woody materials ;L, F and H for organic layers developed mainly from leaves, twigs, woodymaterials, and a minor component of mosses ; and A, B and C for mineralhorizons .Subdivisions of the master horizons are denoted by suffix lettersappended to the master horizon symbol (see Figure 2, Table 2, and glossary) .The A horizon is at or near thesurface in the zone of maximumaccumulation of organic matter (Ah),or removal of materials in solutionand suspension (Ae) .
