Question

Consider the following statements regarding red and yellow soils:

1. They are generally found in regions of high rainfall and low temperature.

2. They are poor in nitrogen, phosphorus, and humus.

• A. 1 only
• B. 2 only
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

Answer:

B. 2 only

• Correct Answer: Option 2 only

• Red and yellow soils are characterized by the following properties:

• Statement 1 is incorrect. Red and yellow soils are NOT found in regions of high rainfall and low temperature. In fact, they are typically found in areas with moderate to low rainfall and relatively higher temperatures. These soils are common in the peninsular regions of India, particularly in states like Tamil Nadu, Karnataka, Andhra Pradesh, Telangana, eastern Maharashtra, Madhya Pradesh, Odisha, and parts of Jharkhand. They develop under semi-arid to sub-humid conditions with seasonal rainfall.

• Statement 2 is correct: Red and yellow soils are indeed poor in nitrogen, phosphorus, and humus. This is because:The hot climate in regions where these soils are found leads to rapid decomposition of organic matter, resulting in low humus content

• Leaching and weathering processes contribute to the deficiency of nutrients like nitrogen and phosphorus

• These soils are generally acidic in nature, which further affects nutrient availability

• The red color of these soils is due to the presence of iron oxides (ferric oxide), while the yellow color indicates hydration of iron oxides in some areas or lesser iron content. While these soils lack fertility in terms of nitrogen, phosphorus, and humus, they can be productive for certain crops when properly managed with appropriate fertilization.
