What is the texture of alluvial soils?

  1. Sandy

  2. Clayey

  3. Loamy

  4. Silty


Correct Option: C
Explanation:

Alluvial soils are typically loamy in texture, meaning they contain a mixture of sand, silt, and clay.

What is the color of alluvial soils?

  1. Red

  2. Black

  3. Brown

  4. Gray


Correct Option: C
Explanation:

Alluvial soils are typically brown in color due to the presence of organic matter and iron oxides.

What is the pH of alluvial soils?

  1. Acidic

  2. Neutral

  3. Basic

  4. Alkaline


Correct Option: B
Explanation:

Alluvial soils typically have a neutral pH, meaning they are neither acidic nor alkaline.

What is the fertility of alluvial soils?

  1. Low

  2. Medium

  3. High

  4. Very high


Correct Option: C
Explanation:

Alluvial soils are typically very fertile due to the presence of organic matter and nutrients.

What is the drainage of alluvial soils?

  1. Poor

  2. Moderate

  3. Good

  4. Excellent


Correct Option: C
Explanation:

Alluvial soils typically have good drainage due to their sandy or loamy texture.

What is the water-holding capacity of alluvial soils?

  1. Low

  2. Medium

  3. High

  4. Very high


Correct Option: C
Explanation:

Alluvial soils typically have a high water-holding capacity due to their loamy texture and the presence of organic matter.

What is the cation exchange capacity of alluvial soils?

  1. Low

  2. Medium

  3. High

  4. Very high


Correct Option: C
Explanation:

Alluvial soils typically have a high cation exchange capacity due to the presence of clay minerals and organic matter.

What are the major crops grown in alluvial soils?

  1. Rice

  2. Wheat

  3. Maize

  4. Sugarcane


Correct Option:
Explanation:

Alluvial soils are suitable for growing a wide variety of crops, including rice, wheat, maize, sugarcane, and vegetables.

What are the major problems associated with alluvial soils?

  1. Flooding

  2. Erosion

  3. Salinity

  4. Alkalinity


Correct Option:
Explanation:

Alluvial soils are prone to flooding, erosion, salinity, and alkalinity, which can affect crop yields and soil fertility.

What are the management practices used to improve the productivity of alluvial soils?

  1. Proper irrigation

  2. Fertilization

  3. Drainage

  4. Soil conservation


Correct Option:
Explanation:

Proper irrigation, fertilization, drainage, and soil conservation practices can help to improve the productivity of alluvial soils.

Which of the following is not a characteristic of alluvial soils?

  1. They are formed by the deposition of sediments by rivers.

  2. They are typically found in floodplains and deltas.

  3. They are usually acidic in nature.

  4. They are generally fertile and productive.


Correct Option: C
Explanation:

Alluvial soils are typically neutral or alkaline in nature, not acidic.

What is the main factor responsible for the fertility of alluvial soils?

  1. The presence of organic matter

  2. The presence of clay minerals

  3. The presence of sand particles

  4. The presence of silt particles


Correct Option: A
Explanation:

The presence of organic matter is the main factor responsible for the fertility of alluvial soils.

Which of the following crops is not commonly grown in alluvial soils?

  1. Rice

  2. Wheat

  3. Maize

  4. Cotton


Correct Option: D
Explanation:

Cotton is not commonly grown in alluvial soils because it prefers well-drained soils.

Which of the following is a problem associated with alluvial soils?

  1. Flooding

  2. Drought

  3. Salinity

  4. Alkalinity


Correct Option: A
Explanation:

Flooding is a common problem associated with alluvial soils because they are often located in floodplains.

Which of the following is a management practice used to improve the productivity of alluvial soils?

  1. Proper irrigation

  2. Fertilization

  3. Drainage

  4. All of the above


Correct Option: D
Explanation:

Proper irrigation, fertilization, and drainage are all management practices used to improve the productivity of alluvial soils.
