Q6. Watermelons grow best in
- (a) Alluvial soil
- (b) Sandy soil
- (c) Black soil
- (d) Laterite soil
Show Answer
Solution: (b)
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.
Q7. The most extensive soil cover of India comprises.
- (a) laterite soils
- (b) black soils
- (c) alluvial soils
- (d) marshy soils
Show Answer
Solution: (c)
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.

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.
Q9. In which one of the following States is laterite soil found?
(a) Kerala
(b) Uttar Pradesh
(c) Rajasthan
(d) Maharashtra
Show Answer
Solution: (d)
Laterite soil is a type of soil that is formed from the weathering of rocks in tropical and subtropical regions. It is characterized by its red, brown, or purple color and is rich in iron and aluminum.
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.

(a) Eastern Region only
(b) Southern Region only
(c) Eastern & Southern part of the Deccan Plateau
(d) None of these
Show Answer
Solution: (C)
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.
Q11. The soil of Kerala is rich in which of the following soils?
(a) Alluvial Soil
(b) Laterite Soil
(c) Sandy Soil

Show Answer
Solution: (B)
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.

18 .The best suitable soil for plant growth is
A)Sandy
B)Loamy
C)Clay
D)None of the above
Show Answer
Correct Answer(b) : Loamy
The ideal blend of soil for plant growth is called loam. Often referred to as topsoil or black dirt by landscape companies, loam is a mixture of sand, clay, and silt. The estimated mixture is 40% sand – 40% silt – 20% clay.
- The silt soil is more fertile compared to the other three types of soil.
- Clay is the densest and heaviest type of soil which does not drain well or provide space for plant roots to flourish.
- Loam is the equilibrium type of soil. It is a combination of sand, silt and clay such that the beneficial properties of each are included. For instance, it has the ability to retain moisture and nutrients; hence, it is more suitable for farming. This soil is also referred to as agricultural soil as it includes an equilibrium of all three types of soil materials, being sandy, clay, and silt, and it also happens to have humus.

B)Black soil is the ideal soil for the production and growing of Cotton.
C)Both A and B
D)None of the above
Show Answer
Correct Answer : Both A and B
The ideal conditions for the production of cotton are:
Climate: Cotton grows well in warm and moist climate where summer is long and where there is salinity in the soil.
Temperature: Cotton grown well in a temperature of 24°C. But cotton bursts out, high temperature is injurious.
Rainfall: 60-100 cm rainfall is essential for the cultivation of cotton.
Soil: Loamy soil mixed with lime and potash is good for cotton. Cotton grows well in Black Cotton Soil which is sticky in nature and has water retentive capacity.
