Question

5. Collect at least three samples of different types of soil. From where and how did you managed to get these soil samples. Observe them carefully and on the basis of your own observations, describe, how they are similar or different from each other. Also attach the samples (a small amount) along with their description.

Answer 1

Answer:

Soil types

Clay soils are heavy, high in nutrients, wet and cold in winter and baked dry in summer.

Sandy soils are light, dry, warm, low in nutrients and often acidic.

Silt soils are fertile, light but moisture-retentive, and easily compacted.

Loams are mixtures of clay, sand and silt that avoid the extremes of each type.

Answer 2

Answer: The explanation is given below. The samples collected are clay, sandy and slit soil.

Explanation:

• Clay soil is distinguished from other types of soil by the presence of very tiny mineral particles and a relatively low proportion of organic matter.
• Because there is not a lot of space between the mineral particles, the soil that is produced as a result is extremely sticky, and it does not drain water very well at all.
• Clay is commonly present near fresh water lakes, ponds or rivers. Soil found in deserts and sea shores is usually rich in sand.
• I found it near lakeside in my Area.
• Sand and other types of sandy soil are produced when the smallest or finest particles of weathered rocks combine together.
• Because of their very low nutritive value and inadequate capacity to keep water, this type of soil is considered to be the worst possible choice for agriculture and the cultivation of plants.
• They are most common in the arid to semi-arid regions of western Rajasthan, southern Haryana, south-west Punjab, and north-western areas of Gujarat, as well as along the east and west coasts of India.
• I found it from Rajasthan.
• Slit: When wet, soil that is silty, not gritty or rocky, is dangerously slippery. If there is more than 80 percent silt present in the soil, then the soil itself might be referred to as silt. Rocks such as siltstone are formed when deposits of silt are compacted and the grains are forced together under pressure. Silt is produced when rock undergoes erosion, also known as wearing away, at the hands of water and ice.
• Silt is easily carried by flowing currents, and one of the most common places to find it is in close proximity to rivers, lakes, and other bodies of water.
• I found it near the riverside in my area.
