GEOG 3080 Lecture Notes - Vertisol, Silt, Atterberg Limits
Document Summary
Soil color: affects the absorption of solar radiation, valuable clues to the nature of soil properties and conditions, munsell color chart, soil samples re view through holes to match with color on chart, hue, dominant spectral color, red, yellow, influenced by mineralogy. White are rich in salts or cabonates: value, degree of darkness or lightness (0= black, 10= pure white, chroma, purity and saturation of the color (intensity of brightness) which increase with decreasing grayness. Soil structure: arrangements or organization of the particles in the soil, relates to the grouping of primary soil particles into aggregates or peds, peds, smallest natural cluster of particles in a soil, soil structure is important because it controls, drainage, rooting of plants, how well the soil delivers nutrients to plants, aeration, how well the soil delivers nutrients to plants, affected by human action, aggregates affect the arrangement of soil pores between them.
