Correct option is B
The correct answer is: B) 150 cm
Explanation:
In deep soil, the soil profile is generally studied up to a depth of 150 cm. This depth allows for the examination of the various layers of the soil, including the surface, subsoil, and underlying layers that are important for plant growth and root development.
In deep soil, the soil profile is generally studied up to a depth of 150 cm. This depth allows for the examination of the various layers of the soil, including the surface, subsoil, and underlying layers that are important for plant growth and root development.
The topsoil and subsoil typically extend to this depth, and it provides sufficient information for soil fertility assessment, nutrient availability, and water retention properties.
Information Key Points:
This depth covers the topsoil and subsoil, which are vital for crop growth.
Soil characteristics at this depth help in assessing the soil's fertility, water retention, and root penetration.
