Document Summary
Illuviation- material leached in one layer enter and accumulate into another. Along with eluviation are types of translocation. Loam: balanced mixture of materials for plant growth. Plants most efficient when soil at field capacity (max water for roots) Colloids: tiny particles of material suspended in soil. Cation exchange capacity (cec)- total number of cations that soil capable of adsorbing and exchanging. Basic/alkaline soil: soil high in base cations. Laterization- leaches most cations and silica in humid climates. Calcification- makes illuviated accumulation of calcium carbonates in arid. Decline in soil e from water and wind. But actually higher than what was estimated: human impacts on soils. Salinization- concentrates salts in soils in climates with high evapotranspiration. Podzolization- eluviation-illuviation of iron and aluminum oxides in acid regime. Plinthite/laterite: quarried in blocks and used to build. Calcification: calcium carbonate or gam carbonate accumulates in b and c horizons. Salinizatoin: salts dissolved in soil water migrate to surface.
