Naser asks, “I have a problem with deep cracks forming in my lawn soil. Answer: A Vertical section through different layers of the soil is called the Soil profile. A sticky, bluish-gray subsurface layer of clay found in some waterlogged soils. 9.4 (c)] from this soil. Thus, the soil can be classified as sandy, clayey and loamy. Answer: (i) It is made up of tiny soil-particles without air spaces.

Clayey soil, therefore, gets easily water-logged. Soil Texture Triangle Source: USDA Clay soil is hard work and has the problem of poor drainage, hence flooding in the rain and baking hard as concrete in the sun. (iii) Water cannot pass through it, so it holds lot of water and becomes sticky. Soil layers tend to vary from place to place as to their number, individual thickness, colour, physical and chemical characteristics. Choose the right answer from the four alternatives given below: Question 1(i). They become very hard on drying and sticky on wetting. Three main features of this type of soil are – This soil consists of various proportions of sand, silt and clay. If the proportion of fine particles is relatively higher, then it is called clayey soil. Question 3. Black soil in India is rich in metals such as Iron, Magnesium and Aluminum.

The principal layers discussed in Section 1.4, The soil and the subsoil of mineral soils, are subdivided into thinner layers called master horizons . According to Atterberg (1911), soils can be classified based on plastic indices as shown in table. CLAYEY SAND – Will form ribbon 5 – 15 mm, soil particles will slightly hold together, soil is sticky when wet, many sand grains stick to fingers, soil discolours fingers with clay stain. Tick ( ) the correct option: 1.
