Question

3. Try to find out the moisture content of a soil sample. One method is
given here.
Activity: Take 100g soil. (Take help from any shopkeepers to weigh
the soil.) Place it on a newspaper in the sun and allow it to dry for two
hours. This activity is best done in the afternoon. Take care that the
soil does not spill outside the newspaper. After drying it, weigh the soil
again. The difference in the weight of the soil before and after drying
gives you the amount of moisture contained in 100 g of soil. This is
called the percentage moisture content.
Suppose your sample of soil loses 10 g on drying. Then
Per cent of moisture in soil =
wt. of moisture (g)
x100
Original wt. of soil sample (g)
In this example
Per cent of moisture insoil
10x100
100
10%​
