3 .

Which of the following is engineering properties of black soils?

A)

Low bearing capacity

B)

High compressibility

C)

Low shearing strength

D)

All of the above.

Correct Answer : All of the above.

4 .

Black soils are derived from how many types of rocks?

A)

1

B)

2

C)

3

D)

4

Correct Answer : 2

Most of the black soils are derived from two types of rocks, the Deccan and the Rajmahal trap, and ferruginous gneisses and schists occurring in Tamil Nadu. The former are sufficiently deep while the later are generally shallow.

5 .

Name the soil with low shearing strength and high compressibility?

A)

Desert soils

B)

Black soil

C)

Marine deposits

D)

Alluvial

Correct Answer : Marine deposits

6 .

Which soil is suitable for the growth of cotton?

A)

Alluvial

B)

Black soil

C)

Desert soils

D)

Marine deposits

Correct Answer : Black soil

7 .

Laterite and Lateritic Soils are suitable for the growth of?

A)

Tea

B)

Coconut

C)

Rubber

D)

All the above

Correct Answer : All the above

Due to intensive leaching and low base exchange capacity, typical laterite soils generally lack fertility and are of little use for crop production. But when manured and irrigated, some laterites and lateritic are suitable for growing plantation crops like tea, coffee, rubber, cinchona, coconut, etc. In low lying areas paddy is also grown

8 .

Which soils are also called as regur soils?

A)

Black soil

B)

Desert soils

C)

Alluvial

D)

None of the above

Correct Answer : Black soil

These soils are also called as regur soils. Central India and Deccan plateau mainly constitutes this type of soil.

9 .

In how many groups Indian soil is divided?

A)

6

B)

7

C)

8

D)

9

Correct Answer : 8

The Indian Council of Agricultural Research (ICAR) set up an All India Soil Survey Committee in 1953 which divided the Indian soils into eight major groups. They are (1) Alluvial soils, (2) Black soils, (3) Red soils, (4) Laterite and Lateritic soils, (5) Forest and Mountain soils, (6) Arid and Desert soils, (7) Saline and Alkaline soils and (8) Peaty and Marshy soils

10 .

Which soil is formed from arid conditions with practically negligible rainfall?

A)

Red Soil

B)

Black soil

C)

Alluvial

D)

Desert soils

Correct Answer : Desert soils

These soils are found in Thar desert in the Indian state of Rajasthan. This soil is formed from arid conditions with practically negligible rainfall. This type of soil is highly pervious and has a low density. It requires densification to increase its bearing capacity and shearing strength. Commonly recognised plants that grow in these soils are cacti.
