Question

Which of the following statement is not correct?
A) If soil contains a greater proportion of big particles it is called sandy soil.
B) If the proportion of fine particles is relatively higher, then it is called clayey soil.
C) The soil is classified on the basis of the proportion of particles of various sizes.
D) The best topsoil for growing plants is clay soil. It is a mixture of sand, dust and another type of soil particle known as silt.

Answer 1

Hint: The relative content of different-sized particles in the soil, such as sand, silt, and clay, is indicated by texture. The amount of water and air that soil holds, as well as the rate at which water can enter and move through it, are all influenced by texture.

Complete answer:
Clay soil can hold more total water than most other soil types, and while only approximately half of this is available to plants, crops rarely suffer from drought. Because they swell when wet and shrink when dry, these soils can undergo some reorganisation as a result of weather.

Because loamy soil has more nutrients, humus, and moisture than sandy soil, it is the ideal soil for growing plants. It also has higher water and air infiltration capabilities.

It has the ideal proportions of each type of soil and humus, both of which are important for growth. Sandy soil may hold air, while clayey soil can hold water. As a result, loamy soil is regarded as the ideal gardening and farming soil. The best topsoil for growing plants is clay soil. It is a mixture of sand, dust and another type of soil particle known as silt.

Hence, option D is an incorrect statement.

Note: Loamy soils have a mix of sand, clay, and silt particles, and are considered the most fruitful soil type. It’s advantages are as follows:
- Due to its water-holding capacity, it is drought tolerant.
- When opposed to clay, it warms up faster in the spring.
- Can store nutrients, resulting in rich soils.
- Air and water infiltration are both good.
