Which activity would you do to find out presence of moisture in soil sample? Describe it with a diagram
Answers
The soil in natural state contains lots of moisture that helps in the growth of the plants. This theory can be easily proved by taking some soil in a test tube and heat it to a high temperature.
Gradually, the water vapor arises up the test tube and reaches to colder topmost part of the test tube, where the these vapors may condense due to the touch of the colder surface, if the test tube is closed, thus proving the existence of water in the soil.
If the test tube is open, the water vapors escape out in the atmosphere and if the soil is weighed before and after the heating, the difference in weight proves that soil contains water.
HELLO DEAR,
GIVEN:- Which activity would you do to find out presence of moisture in soil sample? Describe it with a diagram.
ANSWER:- By the process of leaching we can find the presence of moisture in soil sample.
Subtracting the weight of dry soil from the weight of the moist soil and then dividing by the weight of the dry soil. By using the above process we can find the about the presenter moist in soil.
ln agriculture field we can say that leaching is the loss of water soluble plant nutrition from the soil due to rain and irrigation.
