What are properties of Soil?

In this article, we will discuss ‘Properties of Soil’ from chapter ‘Soil’ out for Class 7 Science.

 Percolation rate of water in the soil

• Percolation is the property of absorption of water by soil.
• If we pour a bottle of water on the floor and another bottle of water in the soil, the water on the floor will flow down but water in the soil will be absorbed.
• The percolation rate is the amount of water absorbed by any soil at any given time.
• Formula for calculating percolation rate is,

       Percolation rate (ml/min) = amount of water (ml) / percolation time (min).

• For example, If 200 ml of water is percolated through the soil sample in 40 min. Calculate the rate of percolation.

Solution – Rate of percolation is = amount of water (ml)/ percolation time (min)

= 200 ml/ 40 min

= 5 ml/ min

Ans- The rate of percolation is 5 ml/ min.

Moisture in soil

• Moisture is the amount of water present in the soil.
• During summer, the water content in the soil evaporates and moves up which reflect the sunlight, thus the air above soil seems to shimmer.
