Answer 2

The proportion of sand, silt and clay in a soil sample determines its (b) texture.

• The texture of soil determines the size of particles present in it. It tells us about the water holding capacity and porosity of the soil.
• Clay soil has a fine particle size and hence, has a fine texture. It has high water holding capacity with low porosity.
• Sandy soil has a large particle size and hence, has a coarse texture. It has low water holding capacity with high porosity.
• The particle size of silt soil is intermediate to the particle size of clay and sandy soil.
