Test: Soil of Telangana - Question 4
What are the key characteristics of Red Soils in India?
Detailed Solution for Test: Soil of Telangana - Question 4
Red soils in India are known for being light textured with a porous and friable structure. They are typically neutral to acidic and are deficient in essential nutrients such as nitrogen, humus, phosphoric acid, and lime. These soils do not contain lime Kankar and free carbonates, making them distinctive in their composition.
Test: Soil of Telangana - Question 5
Which type of soil in India is characterized by deep cracks during the dry season and is suitable for growing cotton?
Detailed Solution for Test: Soil of Telangana - Question 5
Black soils, also known as "Black cotton soils," are predominantly clay soils in India. These soils exhibit deep cracks during the dry season and are notably suitable for cultivating cotton due to their unique properties. While deficient in certain nutrients like nitrogen and phosphoric acid, they are rich in calcium, potash, and magnesium, making them favorable for specific crops like cotton.
Test: Soil of Telangana - Question 6
Which type of soil in India is red to reddish-yellow in color, low in essential nutrients, and formed under conditions of high rainfall with alternating dry and wet periods?
Detailed Solution for Test: Soil of Telangana - Question 6
Laterites and lateritic soils in India are characterized by their red to reddish-yellow color and scarcity of essential nutrients like nitrogen, phosphorus, potassium, lime, and magnesia. These soils are typically formed in-situ under specific environmental conditions involving high rainfall with alternating dry and wet periods, leading to significant leaching of soil colloids and silica.
Test: Soil of Telangana - Question 7
Which soil type in India is light textured, porous, and friable, with two distinct classes based on their structure and composition?
Detailed Solution for Test: Soil of Telangana - Question 7
Red soils in India are characterized by their light texture, porous nature, and friable structure. They are divided into two classes: red loam with cloddy structure and concretionary materials, and red earths with loose, permeable topsoil and a high content of secondary concretions. These distinctive classes exhibit unique characteristics that influence their agricultural suitability and nutrient composition.
Test: Soil of Telangana - Question 8
What is a key characteristic of alluvial soils that makes them suitable for supporting various crops?
Detailed Solution for Test: Soil of Telangana - Question 8
Alluvial soils, despite lacking nitrogen, humus, and phosphorus, are known for their fertility levels, making them suitable for supporting various crops. These soils are typically found along rivers, deposited by floodwaters, and are essential for agriculture due to their productive nature.
Test: Soil of Telangana - Question 9
In which type of soil are white salt incrustations commonly found, leading to poor drainage and rendering them infertile for cultivation?
Detailed Solution for Test: Soil of Telangana - Question 9
Saline and alkaline soils are characterized by white salt incrustations and poor drainage, making them infertile for cultivation. These soils are typically found in regions with slightly higher rainfall than deserts and have salt-rich surface layers, posing challenges for agricultural activities.
Test: Soil of Telangana - Question 10
Which type of soil, despite being shallow and infertile for field crops, plays a crucial role in timber and fuel production due to its ecological significance?
Detailed Solution for Test: Soil of Telangana - Question 10
Forest and hill soils, occurring at both high and low elevations with sufficient rainfall for tree growth, are vital for timber and fuel production despite being shallow and infertile for traditional field crops. These soils highlight their ecological importance by supporting forest ecosystems and sustainable resource utilization.
Test: Soil of Telangana - Question 11
What distinguishes peaty and marshy soils, making them suitable for successful rice cultivation with proper drainage and fertilization?
Detailed Solution for Test: Soil of Telangana - Question 11
Peaty and marshy soils, prevalent in wet areas like Kerala and coastal regions, are characterized by their black, heavy, and acidic composition. These soils develop from slowly decomposing vegetation and, with adequate drainage and fertilization, support successful rice cultivation due to their unique properties.
Test: Soil of Telangana - Question 12
What is the predominant soil type in Telangana, covering around 48% of the state's area?
Detailed Solution for Test: Soil of Telangana - Question 12
In Telangana, red soils are the dominant soil type, constituting approximately 48% of the state's expanse. These soils derive their characteristic red color from iron oxides resulting from the weathering of ancient metamorphic rocks. They are mainly found in districts like Mahabubnagar, Nalgonda, Karimnagar, Khammam, Rangareddy, and Nizamabad. Red soils are known for their fertility and are suitable for various crops.
Test: Soil of Telangana - Question 13
Which soil type in Telangana is especially conducive to cotton cultivation due to its high water retention capacity?
Detailed Solution for Test: Soil of Telangana - Question 13
Black soils, also known as regur soils, are specifically advantageous for cotton cultivation in Telangana because of their excellent water retention capabilities. These soils, forming about 25% of the state's area, are formed from volcanic rocks and lava flow. They are prominently present in districts like Adilabad, Rangareddy, and Nizamabad. The unique properties of black soils make them well-suited for cotton and certain other crops.
