Question

Which is the best for plant growth?
A. Loamy soil
B. Silt
C. Sandy soil
D. Clay soil

Answer 1

Hint: Soil is very important for the proper growth of plants. An ideal soil must have all the components- silt, sand, and clay in proper amounts with appropriate minerals for efficient growth. But most importantly it must have a proper retention and drainage property, which is the most important factor for choosing a soil for plant growth.

Complete answer:
Loamy soil is an ideal consideration for the growth of plants during gardening and agriculture because it has a high retention capacity. It retains water and nutrients to a considerable extent shedding off the excess. Also, they have the right percentages of silt, clay, and sand thereby increasing the aeration property. Therefore, it is the most preferred candidate for plant growth.
Therefore, option (a) is the correct option.

Silt is made up of granular sized soil particles whose size ranges between sand and clay with minerals like quartz and feldspar. Therefore, the water retention capacity is very less and so the growth of plants is not possible. So, option (b) is not the correct option.

Sandy soil is granular and the granules are quite big with some rocks and minerals particles as well. This will not let the roots of the plants to anchor itself. Therefore, this is also not the correct option.

Clay is very fine particles of rocks and soil particles which are clayey. They can retain a high amount of moisture along with minerals and traces of organic matter. But this soil is unsuitable because of its no drainage property. Therefore option (d) is also not correct.

Hence, the correct answer is option (A).

Note: Loamy soil is found in the regions of Punjab, Haryana, Bihar, and Uttar Pradesh, especially in the Indo-Gangetic region. It contains the appropriate amount of silt, clay, and sand by weight, that is forty , twenty and forty percent .It contains three layers of the soil-the dark brown layer on the top, the pale brown subsurface layer, and the red layer under the soil. Loamy soil is used as a component along with mud, sand, water, and binding substances for the construction of bricks.
