Pavan picked up a lump of soil and observed that it has very fine soil particles and is tightly packed. Which type of soil should he label the sample as?
∙ Clay soil is the type of soil that is composed of fine particles. Hence, it has very few air spaces. Unlike sandy soil, it will not flow out of the hand if we hold it in our fist.
∙ Sand particles are quite large. They cannot fit close together, so there are large spaces between them. These spaces are filled with air. So, it has highest air spaces bewteen its particles.
∙ Loamy soils have particle size in between those of sandy and clayey soils. So, it has air spaces between those of sandy and clayey soil.
∙ The rotting dead matter in the soil is called humus.
