A competent person would need to conduct tests such as sieve analysis, hydrometer analysis, Atterberg limits tests, moisture content determination, and soil classification tests based on the Unified Soil Classification System (USCS) or AASHTO classification system to accurately classify soil types.
The scientific name of soil is pedology. It is the branch of science that deals with the study of soil and its formation, classification, and distribution.
Black soil is a visual classification and the composition of black soils will vary,

Soil gradation is a type of classification that ranks coarse soil based on the size of its particles. Soil gradation is found by studying the results of a sieve analysis or a hydrometer analysis.
The classification of California soils typically relies on factors such as soil texture, mineral composition, and organic matter content. Factors like cultural practices or the personal preferences of farmers are not likely to be used for soil classification. Additionally, climatic conditions may influence soil characteristics but are not a direct classification criterion. Thus, subjective factors or practices unrelated to soil properties are unlikely to be used in the classification process.
AASHTO classification is primarily used for highway construction and is based on the physical properties of soil. USCS classification is more widely used and is based on both the physical and engineering properties of soil. AASHTO provides more detailed guidance for highway design and construction compared to USCS.
A competent person would need to perform a soil classification test, such as the Unified Soil Classification System (USCS) or the American Society for Testing and Materials (ASTM) system. These tests involve analyzing the physical and engineering properties of the soil to determine its classification based on factors like grain size, plasticity, and density.
