Webb8 apr. 2024 · This paper presents the results of a test cycle of two types of silty sand (siSa) with different contents of fine fractions. Fine fractions are understood as soil grains with a grain diameter of less than 63 µm (as the sum of silt and clay fractions). The soils tested had a content of fine fractions of fSi+Cl,1 = 15.14% and fSi+Cl,2 = 20.48%, respectively, … WebbThe second property of soil is its texture, which refers to the relative proportions of sand, silt, and clay particles that make up the soil. Soil texture is important because it determines the soil's ability to hold water and nutrients, as well as its ability to drain excess water.

In the United States, twelve major soil texture classifications are defined by the United States Department of Agriculture. The twelve classifications are sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam, silty clay loam, sandy clay, silty clay, and clay. Soil textures are classified by the fractions of each soil separate (sand, silt, and clay) present in a soil. Classifications are typically named for the primary constituent particle size or a combination of t… WebbThe fine soil is composed of different particle-size fractions, i.e., sand (S), silt (U) and clay (T) which - according to the German particle-size classification - include the following …
