Consider the following statements.  A. Loamy soils are the most aerated soil.  B. Clayey soil has the most water hold capacity.  C. Most amount of fine particles can be observed in sandy soil.  D. Loamy soil consists of sand, clay, and silt.  Which among the following statements are correct?

Consider the following statements.  A. Loamy soils are the most aerated soil.  B. Clayey soil has the most water hold capacity.  C. Most amount of fine particles can be observed in sandy soil.  D. Loamy soil consists of sand, clay, and silt.  Which among the following statements are correct? Correct Answer B, D

Concept:

The different types of soil based on the size of their particles are as shown in the below table. 

Sandy Soil
  • Soil contains a greater proportion of big particles
  • There is a large space between particles which is usually filled by air.
  • Water cannot be held tightly in them

Clayey Soil
  • Soil contains a more proportion of small particles.
  • Water can be held tightly in them.

Loamy soil
  • Soil contains an equal proportion of small and big particles.
  • Consists of silt, sand, and clay.
  • Have accurate water holding capacity and humus.


Explanation:

  • Sandy soil contains large soil particles which cannot be fit closed to each other. This causes a lot of space between them. So, sandy soil is the most aerated soil. Statement A is incorrect. 
  • Statement B says 'Clayey soil has the most water hold capacity. This is true because water can be held in the tiny gaps between the particles of clay. Clay is the finesrt particle among sand, clay and slit and is present in a maximum amount in clayey.
  • Loamy soil has an equal proportion of sand, silt, and clay. So, statement D is correct. 
  • Statement C is incorrect as fine particles are more in clayey soil. 

So, B and D are correct statements

A teacher is trying to introduce her class VII students to different kinds of soil. She begins by introducing the names of three kinds of soil i.e. sandy soils, clayey soil and loamy soil. She explains the properties of each soil in term of its particulate nature. She then demonstrates one sample of each kind of soil and shows the students the difference in percolation rate of an examples.
