6 levels of taxonomy, Soil Series:, Screenshot 2024-10-06 205146, image -…

- - - - Definition of Ultisols: highly weathered leached acidic soil with a B horizon that has high clay content. To be able to determine if a soil is and ultisol soil scientist look to see if it is highly acidic soils that have a horizon of translocated silicate clay, base saturation decreeases with depth
        
        Definition of mollisols: Soils with a dark colored surface horizon containing a lot of SOM - prairie soils. Soil scientists look at the base saturation if it is 50% or more it is a molliols. They also look at the soil to see if it has a mollic epipedon or surface and subsurface horizons that resemble a mollic epipedon
- - - - Andry Series: the aq in the taxonomic class means that it is aquatic soil which means
- - - - Andry Series: the Argiaquoll means that it is a clay accumulation within the soil
- - - - Andry Series: The subgroup is typic which means that it is typical for a Argiaquoll
- - - - Andry Series: Fine-silty, mixed, superactive, thermic. This means that the soil is a fine silty texture, it has a high CEC (this is from the superactive part) and thermic means that it is in lower tempertures
- - - - The series name is Andry series
- - - - A break down of the horizons and what they have in them and what they look like
        
        First there is a Ap horizon which is an A horizon that is plowed. it ranges from 0-10 inches and is dark grayish brown (2.5Y 4/2). The texture is fine sandy loam. In 6-12 inches it is olive brown (2.5 Y 4/3) dry it is also weak fine granular structure; friable; many fine and medium roots, lastly it is strongly acid.
        
        The second one is BA this is a transition horizon between a B horizon and an A horizon. It is10 to 14 inches deep a light olive brown color(2.5Y 5/6) fine sandy loam; weak fine granular structure
        
        The third on is Bt1 it is 14 to 22 inches deep it is an olive brown (2.5Y 4/4) color it has a sandy clay loam texture; weak medium subangular blocky structure; friable. It has some iron depletions and yellowish brown (10YR 5/8) masses of oxidized iron; common clay bridging between sand grains.
        
        The fourth is Bt2 it s 22 to 30 inches deep, olive brown (2.5Y 4/4) color with a texture of sandy clay loam; weak medium subangular blocky structure; friable very strongly acid; gradual smooth boundary. (Combined thickness of the Bt horizon is 15 to 45 inches.). There are many similarities between this Bt1 and the Bt2.
        
        The fifth is Cg with a depth of 30 to 80 inches. A color is olive gray (5Y 4/2) and dark olive gray (5Y 3/2). The texture is sandy loam and yellowish brown (10YR 5/8) loamy sand; loamy sand part is single grain; loose; sandy loam part is massive. There is some iron depletions in loamy sand part. It is extremely acid.
- - - - what the soil horizons look like
        
        The first on would be an 021 it is at a depth of 12 to 6 inches it is very dark grayish brown (10YR 3/2) color. hemic material; about 50 percent fiber, about 30 percent rubbed; It has a massive structure.
        
        The second one is 022 it is at a depth of 6 to 0 inches the color is very dark grayish brown (10YR 3/2) hemic material; about 40 percent fiber, about 20 percent rubbed; it is acid at a depth of 4-8 inches
        
        The third is A11 at a depth of 0 to 6 inches. The color is black (10YR 2/1). The texture is silt loam. The structure is weak granular and about 12 percent fiber
        
        The forth is A12 at a depth of 6 to 13 inches. The color is very dark gray (10YR 3/1). The soil texture is silt loam;
        
        The fifth is B21tg it is at a depth of 13 to 26 inches. The color is very dark gray (10YR 3/1). It has a texture of silty clay loam. The structure is weak medium subangular blocky. It has a few sot Fe-Mn accumulation with some clay films
        
        The sixth is B22tg the depth is 26 to 33 inches. The color is greenish gray (5GY 5/1). The texture is silty clay loam. It has a subangular blocky structure. It has som Fe-Mn concentrations
