Document Summary

Forest soils week five lecture five. Concept of forest soil: forest soil is a medium for plant growth. Forest soil differs from agricultural and other soils: forest soil has a forest floor soil horizon (l, f, h, natural body which chemical, physical and biological properties governed by. Time: soil is a component of the forest ecosystem. Addition, transformation, translocation and loss of materials in naturally occurring biogeochemical cycles. A two-dimensional section or lateral view of a soil excavation. Soil profile is divided into a number of sections referred to as (cid:498)horizons(cid:499) Organic horizon further divided into l, f, h (canadian system: bedrock is also referred to as r horizon. Illuvated: receives leached materials: used as suffixes, design specific properties of the master horizon. Different soil colors occur: mineral composition. Iron = red color: organic matter content. Color can be determined in the field using musell soil color chart. Relative properties of sand, silt, and clay in soil.
