Characteristics of Soil Profile
The profile characteristics studied in the field consist of locating the soil hor izons (based on its colour description that includes the colour name, the Munsell notation), the water state, and the physical state. The physical state is recorded as broken, rubbed, crushed, while the water state of a sample is given either as "moist" or "dry". The Munsell notation is a soil colour system devised originally in the USA and now widely accepted. It is based on the three variables of colour viz., hue, value and chroma. The notation is recorded in the form: hue value/chroma e.g., 7.5R 7/3
