Question

The lower percolation rate refers that the soil
A. Can hold water for less time
B. Can hold water for more time
C. Cannot hold water
D. None of the above

Answer 1

Hint: Soil is composed of minerals, gases, liquids and organic matter and some quantity of microorganisms and humus to support plant and animal life.
Percolation is defined as the movement of water to and from the soil, and percolation rate is the time period in which movement of water occurs through soil. The sandy soil has the highest percolation rate and it allows rainwater not to reach at the greatest depth and hold the water for a short period of time. Sandy soil retains the least rainwater in it.
Lower will be the percolation rate the soil will hold the water for a long time.
The combination of soil factors such as organic matter present in soil that is humus ,microorganism, slits determines the texture ,porosity and goodness of soil.

Complete answer:

> Percolation rate is the rate at which movement of water occurs. When soil has a high percolation rate it will hold water for a very short period of time . So this option is incorrect.
> When the percolation rate is low, soil holds water for more time. Hence, this option is correct.
> Soil always holds some amount of water . So , this option is incorrect.
> Lower percolation rate favours high water holding capacity. Hence, this option is also wrong.

Our correct option is b that it can hold water for more time.

Note:
Soil Types
> Sandy soil: It is acidic soil and is low in nutrients. It is dry soil and is light and warm.
> Clay Soil: This soil has a high nutritive value and is heavy soil.
> Silt Soil: This soil shows high fertility content in it. This soil retains moisture and is light soil.
> Peat Soil: It is a great soil for wildlife. It has a high nutritive value. It has a large amount of carbon deposits
> Chalk Soil: It is mainly composed of calcium carbonate but this soil is not good for wildlife .
> Loam Soil: Loam is soil composed mostly of sand, silt, and a smaller amount of clay.
