Laterite soils are primarily found in which climatic regions?

  1. Temperate

  2. Tropical and Subtropical

  3. Polar

  4. Mediterranean


Correct Option: B
Explanation:

Laterite soils are formed under tropical and subtropical conditions, where high temperatures and heavy rainfall promote intense chemical weathering.

What is the primary parent material for the formation of laterite soils?

  1. Igneous Rocks

  2. Sedimentary Rocks

  3. Metamorphic Rocks

  4. All of the above


Correct Option: D
Explanation:

Laterite soils can be formed from various parent materials, including igneous, sedimentary, and metamorphic rocks.

Which process is responsible for the formation of laterite soils?

  1. Erosion

  2. Leaching

  3. Weathering

  4. Deposition


Correct Option: C
Explanation:

Laterite soils are formed through intense chemical weathering under tropical and subtropical conditions.

What is the characteristic color of laterite soils?

  1. Red

  2. Black

  3. Yellow

  4. Brown


Correct Option: A
Explanation:

Laterite soils typically exhibit a reddish color due to the presence of iron oxides and hydroxides.

Laterite soils are known for their:

  1. High Fertility

  2. Low Fertility

  3. Neutral pH

  4. Alkaline pH


Correct Option: B
Explanation:

Laterite soils are generally low in fertility due to the leaching of nutrients and the presence of iron oxides and hydroxides.

Which of the following is a common characteristic of laterite soils?

  1. High Clay Content

  2. Sandy Texture

  3. Good Drainage

  4. Waterlogged Conditions


Correct Option: A
Explanation:

Laterite soils often have a high clay content, which contributes to their poor drainage and low fertility.

Laterite soils are commonly associated with which type of vegetation?

  1. Tropical Rainforests

  2. Temperate Forests

  3. Grasslands

  4. Deserts


Correct Option: A
Explanation:

Laterite soils are often found in regions with tropical rainforests, where the high temperatures and rainfall promote intense weathering.

Which of the following is a major constraint associated with laterite soils?

  1. Erosion

  2. Salinity

  3. Alkalinity

  4. Organic Matter Content


Correct Option: A
Explanation:

Laterite soils are prone to erosion due to their poor structure and low organic matter content.

Laterite soils are often associated with which type of terrain?

  1. Flat Plains

  2. Mountainous Regions

  3. Coastal Areas

  4. River Valleys


Correct Option: B
Explanation:

Laterite soils are commonly found in mountainous regions, where the steep slopes and high rainfall promote intense weathering.

Which of the following is a common management practice for improving the fertility of laterite soils?

  1. Liming

  2. Fertilization

  3. Irrigation

  4. Terracing


Correct Option: B
Explanation:

Fertilization is a common practice to improve the fertility of laterite soils by adding essential nutrients.

Laterite soils are typically characterized by:

  1. High Cation Exchange Capacity (CEC)

  2. Low Cation Exchange Capacity (CEC)

  3. Neutral pH

  4. Alkaline pH


Correct Option: B
Explanation:

Laterite soils generally have a low CEC due to the presence of iron oxides and hydroxides, which have a low capacity to hold cations.

Which of the following is a common limitation of laterite soils for agricultural purposes?

  1. Drought Tolerance

  2. Nutrient Deficiency

  3. Waterlogging

  4. Erosion Resistance


Correct Option: B
Explanation:

Laterite soils are often deficient in essential nutrients, such as nitrogen, phosphorus, and potassium, which can limit crop growth.

Laterite soils are known for their:

  1. Good Drainage

  2. Poor Drainage

  3. High Water-Holding Capacity

  4. Low Water-Holding Capacity


Correct Option: B
Explanation:

Laterite soils typically have poor drainage due to their high clay content and low organic matter content.

Which of the following is a common method for improving the drainage of laterite soils?

  1. Liming

  2. Fertilization

  3. Tillage

  4. Terracing


Correct Option: D
Explanation:

Terracing is a common method to improve the drainage of laterite soils by creating level terraces to reduce erosion and improve water flow.

Laterite soils are often associated with which type of climate?

  1. Temperate

  2. Tropical Monsoon

  3. Mediterranean

  4. Polar


Correct Option: B
Explanation:

Laterite soils are typically associated with tropical monsoon climates, characterized by high temperatures, heavy rainfall, and distinct wet and dry seasons.
