1. Watermelons grow best in
Correct Answer:-B ( Sandy soil )
Description:- Watermelon is a tender, warm-season vegetable. Watermelons can be grown in all parts of the country, but the warmer temperatures and longer growing season of southern areas especially favor it. Watermelons grow best on a sandy loam soil, although yields on clay soils can be increased significantly by mulching raised planting rows with black plastic film.
2. Generally, the soil of the northern plains of India has been formed by
Correct Answer:-B ( aggradation )
Description:- The Northern Fertile Plain lies to the south of Himalayan Region. It is also called the Gangetic Plain. It is a vast plain and level land between the Himalayas in the North and Deccan Plateau in the South. The soil of this plain is built of the sediments brought down by the rivers from Himalayas. Such plain is called an alluvial plain and is very fertile. This plain is one of the largest and most fertile plains of the World.
3. The most extensive soil cover of India comprises.
Correct Answer:-C ( alluvial soils )
Description:- Alluvial soil constitutes the largest soil group in India, constituting 80%” of the total land surface. It is derived from the deposition of silt carried by rivers and are found in the Great Northern plains from Punjab to the Assam valley. Alluvial soils are generally fertile but they lack nitrogen and tend to be phosphoric.
4. Laterite soil is found in which of the following States?
Correct Answer:-D ( Karnataka and Tamil Nadu )
Description:- Laterite soils are found on the highland areas of plateau Karnataka, Kerala, Tamil Nadu and hilly regions of Assam, Rajmahal hills and Chhotanagpur plateau. These are shallow, acidic and less fertile soils. These soils are poor in lime but rich in iron. So these are suitable for plantation of crops like tea, rubber, coffee etc.
5. To which group does the black cotton soil of India belong ?
Correct Answer:-C ( Chernozem )
Description:- Chernozem (meaning: black soil), or “black earth”, is a black-coloured soil containing a high percentage of humus (7%” to 15%”), and high percentages of phosphoric acids, phosphorus and ammonia. It is very fertile and produces a high agricultural yield.
6. Saline and alkaline soils in India are also called as
Correct Answer:-A ( Kallar )
Description:- Regur of Black Cotton Earth soil refers to the dark coloured volcanic soil. Saline and alkaline soils in India are also called as kallar.
7. In which one of the following States is laterite soil found ?
Correct Answer:-D ( Maharashtra )
Description:- Laterite soils in India are found in the Eastern Ghat of Orissa, the Southern parts of Western Ghat, Malabar Coastal plains and Ratnagiri of Maharashtra and some part of Andhra Pradesh, etc. it is rich in aluminium and iron and looks red due to the presence of iron oxides.
8. In which of the following states can you find pink (laterite) soil ?
Correct Answer:-A ( West Bengal and Andhra Pradesh )
Description:- Laterite Soil is found in those regions of India which receive heavy rainfall with alternate dry and wet period. The states where this type of soil can be found are West Bengal, Andhra Pradesh, Bihar, Meghalaya, Assam, Odisha to name a few. The soils are pink in colour due to the presence of iron oxides.
9. Red soil is normally found in India in which regions?
Correct Answer:-C ( Eastern & Southern part of the Deccan Plateau )
Description:- In India, red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern parts of the Deccan plateau. These soils are abundant along the eastern slopes of Western Ghats, Odisha and Chhattisgarh and in the southern parts of the middle Ganga plain. The soil develops a reddish color due to a wide diffusion of iron in crystalline and metamorphic rocks.
10. The soil of Kerala is rich in which of the following soils?
Correct Answer:-B ( Laterite Soil )
Description:- Laterite soil covers the majority of area in Kerala. They cover about 65 per cent of the total area of the State, occupying a major portion of the midland and mid-upland regions and are the most extensive of the soil groups found in Kerala. Heavy rainfall and high temperature prevalent in the State are conductive to the process of laterisation.
