Types of Dirt
Andisols Andisols (from the Japanese ando – black soil) typically form from the weathering of volcanic materials such as ash, resulting in minerals in the soil with poor crystal structure. These minerals have an unusually high capacity to hold both nutrients and water, making these soils very productive and fertile.
Aridisols (from the Latin aridus – dry) are soils that occur in climates that are too dry for “mesophytic” plants—plants adapted to neither a too wet nor too dry environments—to survive. The climate in which Aridisols occur also restricts soil weathering processes.
is that dust is (uncountable) fine, dry particles of matter found in the air and covering the surface of objects, typically consisting of soil lifted up by the wind, pollen, hair, etc while dirt is soil or earth.
Dirt is unclean matter, especially when in contact with a person's clothes, skin or possessions when they are said to become dirty.Common types of dirt include: * dust — a general powder of organic or mineral matter * filth — foul matter such as excrement * grime — a black, ingrained dust such as soot * soil — the mix of clay, sand, and ...
Gelisols, in a nutshell, are soils that are frozen. They are soils that have permafrost (frost, i.e. frozen soil, that is present year-round) within 100 cm of the soil surface, or have “gelic” material within 100 cm with permafrost within 200 cm of the surface.

Histosols are soils that are composed mainly of organic materials. They contain at least 20-30% organic matter by weight and are more than 40 cm thick. Histosols typically form in settings where poor drainage inhibits the decomposition of plant and animal remains, allowing these organic materials to accumulate over time.
Oxisols are always a red or yellowish color, due to the high concentration of iron(III) and aluminium oxides and hydroxides. They also contain quartz and kaolin, plus small amounts of other clay minerals and organic matter.
What is Silt Soil? Silt soil is finer than sand, but still feels gritty. Silt is commonly found in floodplains and is the soil component that makes mud. Soils with a lot of silt make excellent farm land, but erode easily. This is the soil blown away in dust storms and carried down stream in floods.
As he described it, soil is the compilation of minerals, air, water, animals and other living matter (and their wastes or decaying bodies) that accumulate in layers and become compacted over time. Indeed, soils are laid down in discrete horizons (his name for those layers) and whose compositions vary over time and space.
Spodosol, one of the 12 soil orders in the U.S. Soil Taxonomy. Spodosols are ashy gray, acidic soils with a strongly leached surface layer. Their suitability for cultivation is limited to acid-tolerant crops and orchards, provided that sufficient lime and fertilizer are applied.
Ultisols (from the Latin ultimus – last) are soils that have formed in humid areas and are intensely weathered. They typically contain a subsoil horizon that has an appreciable amount of translocated clay, and are relatively acidic.
Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or expansive soil. The amount of certain clay minerals that are present, such as montmorillonite and smectite, directly affects the shrink-swell capacity of soil.
