To classify soil under USDA, the following characteristics are considered:
1. Soil Order: The first level of classification is based on the presence or absence of certain soil properties. The 12 soil orders recognized by USDA are:
- Alfisols
- Andisols
- Aridisols
- Entisols
- Gelisols
- Histosols
- Inceptisols
- Mollisols
- Oxisols
- Spodosols
- Ultisols
- Vertisols
2. Soil Suborder: The second level of classification further categorizes the soil order based on additional properties. For example, within the Alfisols order, suborders include Udalfs, Ustalfs, Xeralfs, and Aqualfs.
3. Soil Great Group: The third level of classification focuses on specific soil properties and processes. For instance, within the Udalfs suborder, great groups include Argiudolls, Hapludalfs, and Paleudalfs.
4. Soil Subgroup: The fourth level of classification provides more detailed information about the soil's properties and characteristics. For example, within the Argiudolls great group, subgroups include Rhodic Argiudolls, Typic Argiudolls, and Calcic Argiudolls.
It is important to note that the classification of soil under USDA is a complex process that involves analyzing various physical, chemical, and biological properties. The specific classification of a soil sample would require a detailed analysis by a soil scientist or expert.
